Human Pancrease

2012-04-12T20:40:00.001-07:00

The human pancrease is situated near the curve of the duodenum, in the abdonimal cavity.It has a broad head, a body and a narrow tail.
It functions both as endocrine and exocrine glands.The exocrine part is made up of lobules ,each lobules consits of small alveoli like secreting cells.(acini cells) that secrete pancreatic juice.
Amylose, lipase, nucleases, tripsinogen and chymotripsinogen are the enzymes found in the pancreatic juice along with water and mineral salts.
Lobules drained by small ducts join together to form the pancreatic duct.

Istlets of Langerhans are the endocrine part, that consists of alpha and beta cells .Aplha cells secrete glucagon and beta cells secrete insulin.

How To Get your Google Adsense Account Turned Back On.

So, let me guess... you received a little email from the Google Adsense Team about fradulent clicks... and bla bla bal.. to make a long story short they banned your account. Right? oh and to make matters worse i'm sure they said... uh also we are going to k eep all of the money you have made because we are going to... uh... give it back to uh... uh... give it back to the..... people who paid for those clicks.. yeah.. that's what we are going to do!
Of course the letter was a bit more professional than that.. in fact it was so professional that every thing I have ever read on this subject pointed to one thing... EVERY ONE gets that letter! well not Every one. but its the same letter! then you can appeal your account. and you get another letter... and by the way.. everyone gets the same thing once you appeal. I'm sure it's just some person some place copying and pasting pre written text into an email after they.. psudo read what you had to say. Well, here's the deal. You are here to figure out HOW to get your Adsense Account back on.. reinstated... reactivated.. whatever you want to call it.. you just want to start getting money again. Right? of course. Well here is how it's done!

Article Continued Below

We all know how to make money with Google Adsense, but the question is.. what happens when you get hit with the good ol' fraudlent clicks deal and your ads get turned off? First you Appeal.

Step 1. Appeal

Here's the deal. YOU ARE GUILTY! there is no question about it. I know what you are thinking.. " well not really i'm not guilty... or I'm not THAT guilty" that's not how the computer see's it... it's kinda how God views sin... every one wants to say.. well i'm not THAT bad... well in God's Standard.. you are GUILTY... and Google's Standard..... YOU ARE GUILTY!!!! they computer says so... plain and simple..... so you have to write something.. to make the PEOPLE running those computers believe otherwise..
What to put in your appeal to Google:

So... you want to appeal your little problem and now want to know what to put. Here is your answer. BE HONEST! This is what happened to me.
I was enjoying my October day until I opened my email and found a nice letter from google ... banning my Adsense account! I was pissed I had saved about 350 dollars in there and now.. it's gone! So I appealed... the first thing i wrote.. was just a bunch of WHAT HAPPENED.. PLEASE TELL ME PLEASE TELL ME... I DIDN"T CLICK ON MY ADS!!! Which is true. I didn't click on my ads nor did I know HOW it happend.. I was just writing in a Panic. DON'T DO THIS!!! it's just a waste of time. Take some time and think. Where could these click come from. Then explain.
In my case. I had told my Dad all about google and how the ads were great and I get all this money when people click the ads.... bla bla So my dad decided to "Help me out" by clicking on my ads for me. Of course I noticed a spike of money every once in a while. But I just chalked it up to a good day!
DO NOT LIE

Like God, Google will know when you are lying.... unless it's a really good lie.. then of course only God will know. I was going to tell google that it was a competitor clicking on my ads to get even with me or to hinder my money intake. But I had decided to do the RIGHT THING and just tell the truth. So I told them.. and BAM I was back on. Just do a search and you will see... tell the truth to them.. they will understand.
DO NOT BE A JERK

Take your time.. and cool down.. don't spout off at the fingers to Google about how EVIL they are for taking away your lunch money every day. Remember you get more flies with honey than you do with vinegar... or ....you get.. more beez with honey than with..... uh..poop.... er. something like that. I don' t know... just BE NICE.
APPEAL AGAIN

Appeal Again... and Again... Google will tell you they don't have to read your emails anymore.. but appeal again.. and again.. use words like.. Sorry... and Will you forgive me. Basically stuff you would say to your wife after forgetting her birthday...

The one Secret to getting your Adsense Account Turned Back On is This:
BE HONEST if you are honest the first time around and explain everything and how it won't happen again. YouWILL get your account turned back on.

4. Which of the following conduction sequences is in correct order:a. AV node->internodal pathways->bundle of His->Purkinje fibers->SA node-bundle branchesb. SA node->AV node->Purkinje fibers->bundle of His->bundle branches->internodalpathwaysc. bundle of His->bundle branches->Purkinje fibers->AV node->inter-nodal pathways->SAnoded. SA node->internodal pathways->AV node->bundle or His->bundle branches->Purkinjefiberse. Purkinje fibers->bundle of His->bundle branches->internodal pathways->SA node->AVnode

5. In discussing the conducting fibers of the sino-atrial node, atrio-ventricular node, bundle of His,bundle branches and Purkinje fibers, the following may be stated (regarding one, or all ofthem):a. composed of modified cardiac muscleb. spontaneous rhythmicity and conductivity more highly developed than the rest of the heartc. initiates and transmits a depolarization wave with a rapid rate which passes through allparts of the myocardiumd. can be regulated by the autonomic (visceral) nervous systeme. all of the above

6. If the conducted depolarizations from the sino-atrial node are blocked, the ventriculardepolarizations are initiated in the:a. atrio-ventricular node, which will exhibit rhythmic depolarizations, but at a lower rateb. heart stops functioning because no depolarizations reach the ventriclesc. cardiac muscle of the atrial walls itself begin spontaneous contraction and conductiond. interatrial septume. none of the above

7. What is the effect of a heart block:a. prevents the atria from contractingb. blocks the atrio-ventricular conducting system, thus abolishing the synchronization of atriaand ventriclesc. plugs up the coronary arteries, depriving the heart muscle of oxygen and nutrients, causinglocal cell deathd. would only operate in stress conditionse. causes the ventricles to become the overall heart "pacemaker"

8. A heart block is due to:a. failure of the atrio-ventricular node to receive and/or to transmit depolarizationsb. failure of the sino-atrial node to receive stimulic. failure of the atrio-ventricular node to stimulate atrial muscled. lack of blood supply to the livere. permanent closure of a heart valve

9. The atrio-ventricular node's primary function is:a. conduction of a depolarization wave through the atriab. conduction of a depolarization wave through the ventriclesc. delay conduction from the atria to the ventricles, to allow atrial conduction to be completedd. to act as the heart's overall pacemakere. unknown

11. The fastest conduction speed is within the:a. sino-atrial nodeb. internodal pathwaysc. atrio-ventricular noded. ventricular conducting systeme. moderator band

12. Why is the ventricular conduction system's speed so fast:a. there is much more myocardium to stimulate to contractb. depolarization is less effectivec. gravity has more effect, since this is beneath the atriad. simply because the atrial conduction is firste. it is not faster [trick question]

13. Why does ventricular depolarization and resulting contraction begin in the apex and thenprogress towards the base:a. the heart is positioned more to the left of the body's midlineb. the ventricular conducting system is more extensive than the atrial systemc. this prolongs its action, to prevent overlap with atrial systoled. this produces a milking action which squeezes the maximum amount of blood into the aortaand pulmonary trunke. there is no particular logic

14. Sequential contraction throughout the heart, from cell-to-cell conduction of depolarization, isfrom which feature:a. all-or-none responseb. myogenicityc. syncytial fibersd. independent tonee. autorhythmicity

16. What is the function of the atrio-ventricular node:a. produces a strategic delay from atria to ventricles, permitting ventricular filling to becompletedb. allows one-way conduction from atria to ventriclesc. permits communication between atria and ventricular conducting systemd. can act as a secondary pacemaker if a blockage occurs with the internodal pathwayse. all of the above

17. A strategic delay in conduction from the atria to the ventricles is accomplished by:a. internodal pathwaysb. junctional fibers of the A-V nodec. bundle of Hisd. trabeculae carneaee. S-A node

18. The heart can not be tetanized because:a. it is myogenicb. it is autorhythmicc. of the long refractory period of cardiac muscle cellsd. its tone is independent of the nervous systeme. all of the above

19. The cardiac cycle is:a. the conduction phenomenab. shown by the EKGc. that the more the heart is stretched the more forceful will be its contractionsd. the alternate contraction and relaxation of the atria and the ventriclese. none of the above

20. Of the following, the longest should be:a. atrial systoleb. ventricular systolec. atrial diastoled. ventricular diastolee. none of the above, since they are all of the same duration

21. Which of the following do not occur simultaneously:a. atrial systole and ventricular systoleb. atrial diastole and ventricular diastolec. atrial diastole and ventricular systoled. atrial systole and ventricular diastolee. left ventricular systole and right ventricular systole

22. Cardiac muscle cells form an interconnected mass, permitting cell-to-cell conduction; thissituation if termed:a. syncytiumb. all-or-nonec. toned. myogenicitye. autorhythmicity

How to study biology?

2011-12-05T07:27:00.001-08:00

FORWARD ñ THE WINNING EDGE IN BIOLOGY

Biology must follow the laws of chemistry and physics. However, much of biology cannot be

reduced to or predicted from chemistry and physics. It cannot be understood by a few

fundamental laws like those of physics and it cannot be understood primarily through the

organization and interaction of atoms like chemistry. Biology not only integrates the principles of

chemistry and physics, it has its own unique organization, principles, laws, and theories. Biology

is the ultimate multi-disciplinary science. Learning biology will be different from learning other

subjects.

Learning biology requires both understanding and memorization. Memorization alone will not

serve you well. If you try to memorize everything in biology as if it was just a list of key words, you

will be confused and certainly bored to distraction. Biology is properly viewed as a series of

solutions to the problems faced by living organisms in their environments. If you can identify the

problem, you are more likely to understand the biological solution. Remember, biology is a who,

what, where, when, how, and why kind of science.

Despite its complexity, do not be intimidated. In reality, you donít need to spend more study time

in biology than other subjects if you adopt a smart study system. Understanding the ìbig pictureî

is the key to success. The details, often confusing in their complexity or overwhelming in their

numbers will make sense if you can first understand the problem to which the details are the

solution. The key to effective learning in biology is to memorize the least and to apply this

knowledge to the fullest.

Many of you apply the same study methods from non-science subjects to science classes - and

have difficulty in these classes. Even within the science disciplines, you might get in trouble by

studying the same way in biology as in chemistry or physics. Biology is more information

intensive than chemistry or physics and it has its own logic. It cannot be reduced to a few

concepts and principles from which you can derive the answers to all questions. But if you master

the logic of biology, you will survive and prosper.

If you are looking for an effective, high-yield way to study biology, this Guide is for you. Forget

about plowing through many weighty textbooks and overwhelming yourself with unnecessary

information. Our goal here is to spend minimum effort to achieve maximum results. Bring your

biology learning into focus ñ youíll learn what you need to learn.

As most of you have experienced, biology is not so easy at first, yet it is very learnable if you

know how. The very issue of how to study biology is the focus of this Guide. The survival skills

you learn will accelerate your mastery of biology and improve your grade quickly. Ignoring them

will guarantee that you stay stuck in a rut of inefficiency, which might lead to failure. If you follow

the 5-stage systematic method outlined in this Guide, you will improve your learning significantly,

with a better grade in less study time.- 12 -

Letís get cracking! Get the winning edge today.

ìPerhaps the most valuable result of education is the ability to make yourself do the thing you

have to do, when it ought to be done, whether you want to or not. It is the first lesson that must be

learned.î

--Thomas Huxley

The light microscope

2011-12-05T02:23:00.002-08:00

This was was of he first discovered micoscope in the human history.The disadvantage is that it has a small reslution power and hence is not sufficient to view small organelles. Its resolution power is not small and limited to certain range.
This occurs as a result because the wavelenght of light is limited .To overcome this problem the electron microscope was invented which uses electron beams and hence the resolution power of em is highly increased because the wavelength corresponding to the electron beam is very small.
