Histology of the Adenohypophysis

christoff — Tue, 06 Mar 2012 23:50:49 +0000

This is a quick summary of the histology of the anterior pituitary.

It goes over the different cell types found in the AP, including Acidophils, Basophils and chromophils including the specific secretory cells such as somatotrophs and thyrotrophs.

It looks like this site would be great for a quick USMLE review.

Great and creative video illustrating cardiac dysrhythmias using a few classic pop songs and some talented folks!

How Malaria Works (life cycle)

glimlag — Thu, 09 Feb 2012 21:59:36 +0000

malaria life cycle in man and mosquito.......

Very good images and a good explanation of how malaria infects both human and mosquito systems. Good watch!

Plasmodium life cycle terms::

Sporozoites - what is injected into the next host

Trophozoite - what is growing the the hepatocytes *exoerythrocytic cycle

Merozoites - what leaves the liver and enters the RBCs --> ring stage --> kill RBC --> infect more RBCs or become gametocytes to be taken up by another mosquito --> gametes in mosquito

paroxysms - the symptoms of malaria from toxins released with RBC lysis

Interesting and very informative video about the drug discovery and approval process.

Good ETC Animation.

A video describing the classical complement system

christoff — Mon, 21 Nov 2011 00:06:31 +0000

This is an excellent representation of the classical complement system. I think this is one of the more complete videos I have seen. The classical complement system is the last to be activated and starts with C1 being activated by IgM or IgG (needs two molecules of IgG within close proximity.)

Animation Quiz 1 - Activation of Complement

christoff — Sun, 20 Nov 2011 20:51:57 +0000

A very nice basic animation about complement activation. This will do well for a quick review of complement activation. Additionally this has a 5 question quiz to test yourself afterwards.

A story to help remember the alternate pathway of the immune complement

christoff — Thu, 17 Nov 2011 06:41:43 +0000

It helps me to memorize rogue non-descript terms such as found in complement by tying it to a story.

Chapter 1 - The alternative pathway

Clone3 (C3) was out for a swim(in solution) when his stiches holding his arm together started dissolving due to the water. A beach guard(B) noticed the trouble and started pulling the injured C3(iC3) towards the shore (iC3B). Soon a duck(D) came and started pecking at the beach guard's arm which eventually came off(Ba), leaving the rest of the beach guard(Bb) with injured C3(iC3Bb). A second Clone3(different C3) noticed the trouble and came to the rescue, but in the process of saving the two he rips iC3's arm(C3a anaphylotoxin) off. They swim together(C3b2Bb a C5 convertase) and eventually gets to the beach(cell surface) where C3bBb gets anchored. It now becomes a C3 convertase converting other clone3's into C3b's and anchoring them to the beach.

Chapter 1b -Controlling the C3 convertase

Some beaches(non-self) believe it is proper for C3bBb to convert other clone3's. So mayor properdin encourages them to continue and keeps those who wants to stop the converting away from the convertase(C3bBb).

Other beaches(non-self) do not like the conversions and send in their two swedish goons Hans(H) and Ignus(I) to take care of this fool. Hans holds C3b while Ignus cuts his head off.

The last land mass(self) does not want the conversion and it sends Daffy duck(DAF) and MCP(can't think of something here) to disable this convertase. (lost creative will power)

Telomere replication

christoff — Tue, 15 Nov 2011 04:42:21 +0000

The ends of linear chromosomes pose unique problems during DNA replication. This video shows how molecular mechanisms solve these problems. This video will demonstrate how the lagging strand is elongated by telomerase(using an RNA template) followed by replication by using polymerase alpha.

This is a great video for a quick review on telomeres and telomerases.

Static Elastic Properties of the Lung and Chest Wall

christoff — Thu, 10 Nov 2011 00:49:03 +0000

This is a pretty nice step by step tutorial on the static elastic properties of the lung and chest wall. They are basically explaining the theory of recoil pressure and how it is measured. There are some quiz questions to help you understand.

Embryology - Cardiac Development

christoff — Wed, 02 Nov 2011 00:36:25 +0000

This application describes stages of embryonic heart development. It is a fantastic aid to help visualize the folding of the heart during embryonic development. This application also contains a fair amount of descriptive text.

Pterygopalatine fossa

christoff — Wed, 26 Oct 2011 02:16:57 +0000

This is a neat interactive animation of the pterygopalatine fossa. It will show the different arteries(greater and lesser palatine arteries, posterior inferior alveolar a and more) and nerves (like the opthalmic, lacrimal, and nasopalatine nerve). To me this was a difficult space to visualize and this animation really helps.

Mechanism for blood clotting animation

christoff — Wed, 26 Oct 2011 01:43:05 +0000

This video describes hemostasis mechanism. It is accurate, and fairly complete in its description. It goes over the roles of platelets, Von Willebrand Factor, the intrinsic and extrinsic pathways to clotting and fibrin cross-linking. Really well done for a quick review.

Implantation of the blastocyst

christoff — Tue, 25 Oct 2011 03:46:59 +0000

This is a great video of implantation which starts at approximately week 2. This video will show implantation of the blastocyst into the endometrial wall. It shows the changes of the trophoblast, embryoblast, and the amnionitic and yolk sack.

This animation really helps one to visualize implantation.

Blood cells, Dr.Jastrow's electron microscopic atlas

christoff — Thu, 20 Oct 2011 14:46:48 +0000

This is a good reference site if you are studying the electron micrograph of blood cells. By clicking on each picture you can obtain more information with labels. They have pictures of erythrocyte, monocyte, lymphocyte, granulocyte, eosinophil, basophilthrombocyte, erythrocytes, monocytes, lymphocytes, granulocytes,eosinophil, basophilthrombocytes.

It is a foreign site, so if you do not have a built in translator like on chrome, it might be a bit tricky to read some of the text.

Animations on embryonic development (Week 6 to week 12)

christoff — Tue, 18 Oct 2011 05:43:17 +0000

These are nice sagital and transverse views of lateral infolding that occurs during weeks 6-12. It shows mostly the basics but helps with the visualizaiton of a complex idea.

Aclands Video Atlas of Human Anatomy

christoff — Tue, 18 Oct 2011 05:05:16 +0000

Probably the holy grail for anatomy students. These are excellent videos that describes anatomy.

Great video on bone formation and resorption by AMGEN

christoff — Tue, 18 Oct 2011 04:53:44 +0000

This second film in the bone biology series illustrates how bone forms (modeling) and reforms (remodeling) over time. This video gives an overview of the workings of osteoblasts(bone formation) and osteoclasts(bone resorption). This video is actually pretty accurate even in the details. Showing that Osteoblasts tend to stain blue(because of its alkaline phosphatase) while osteoclasts tend to stain red(because of its tartarate-resistant acid phosphatase). It is a great animation and a fantastic place to start learning about the wonderful world of bones.

Dentalwisdom.com - Animation Studio

glimlag — Fri, 14 Oct 2011 07:13:59 +0000

I used this website to better understand what the TMJ looks like and how it functions and thought the animation was helpful. I haven't really watched the others but they should be fairly helpful for more visual learning.

Cardio vascular Vessel, Pressure, and Flow Questions

A nice little question bank on the cardiovascular system. It is mainly physiology but also has some histology.
