- Muscles.

-Types :-
There are 3 types of muscles each type of muscles has its specific structural and functional unit which is called muscle fiber ( cell):-
1- skeletal muscle has skeletal muscle fiber.
2- cardiac muscle has cardiac muscle fiber.
3- smooth muscle has smooth muscle fiber.


- Innervation of the muscles:-
*skeletal muscle fiber has somatic innervation.
* both cardiac muscle fiber and  smooth muscle fibers have autonomic innervation.
so
-skeletal muscle fiber is under voluntary control
- both cardiac muscle fiber and smooth muscle fibers are under involuntary control.
