Muscle belly
Fleshy, contractile part of named muscle composed of skeletal muscle tissue
Muscle tendon
Non- contractile part of named muscle; connects muscle belly to the bone composed of dense regular connective tissues.
Epimysium
Layer of tissue upon surface of named muscle, surrounds largest structural organization of muscle
Perimysium
Layer of tissue around a fascicle surrounds middle - level of structural organization of muscle.
Ex.
Endomysium
Layer of tissue on each muscle cell/fiber “witin” muscle; surrounds the my o fibrils contained within the deepest structural organization of muscle
