Thick filament

• myofibril

• sarcomere

• actin

• myosin

A sheath of connective tissue surrounding a whole muscle.

• sarcolemma

• sarcoplasmic reticulum

• epimysium

• endomysium

Either actin or myosin; generate the force during a contraction.

• contractile proteins / myofilaments

• actin

• cardiac muscle

• sarcoplasmic reticulum

Voluntary muscle that is attached to the bones and provides the force that moves the bones. It is multinucleate and has striations:

• skeletal muscle

• muscle functions

• cardiac muscle

• smooth muscle

Involuntary muscle tissue found only in the heart. It is uninucleate and has striations.

• cross-bridges

• smooth muscle

• skeletal muscle

• cardiac muscle

Cell membrane of a muscle fiber
