What is epimysium and what type of tissue is it composed of?? |
outermost tissue surrounding the outside of a muscle..composed of dense, irregular collagenous connective tissue |
|
|
Perimesium and what is it composed of?? |
Less dense collagenous CT that surrounds bundles/fascicles of muscle |
|
|
Endomysium |
Composed of reticular fibers and a basal lamina, and it surrounds each individual muscle cell |
|
|
Multiunit smooth muscle |
contains cells that can act independently of each other because each cell has its own nerve supply |
|
|
Unitary smooth muscle |
Contains cells that all contract together because they contain gap junctions allowing for communication between the cells |
