endomysin aroudnskeletal muscle

27
Q
A

endocardium

The lumen (L)
 of the ventricle is lined by a thin endocardium
28
Q
A

epineureum in red

perinerum in blue

29
Q

how can you tell this is myelinated?

A

staining removes lipid so you just see the “container” of the myelin aroundt eh cells

35
Q
A

satellite cells around skeletal muscle

Myosatellite cells or satellite cells are small mononuclear progenitor cells with virtually no cytoplasm found in mature muscle. Satellite cells are precursors to skeletal muscle cells, able to give rise to satellite cells or differentiated skeletal muscle cells.
