Synapse neuromusculaire #2 – eduMedia

Cette animation présente la structure et l’ultrastructure de la jonction neuromusculaire. Des clichés histologiques permettent de mettre en relation la représentation schématisée et la réalité.

The bacteria appear pink. The macrophage (appearing blue) is stretching out and engulfing (eating) them. Macrophages are a type of white blood cell which acts as a 'Pacman' in our bodies - it eats foreign bodies (like bacteria) and digests them. This is part of your body's front line defense against invaders.

Martin Oeggerli  Fibrin is a protein created by the body that works with platelets in the blood to clot a wound. As they reach the wound site, they attach themselves to fibers, and create a mesh. Working with the platelets, they make a scab that covers the wound until it heals. Though, with the naked eye you would never guess that the process looks like this.
