Anatomy
Origin:
The origin of a muscle is the point at which it attaches to a bone (usually) or another muscle. The structure that the origin is attached to is not moved by the contraction of the muscle.
Insertion
The muscle insertion is the point at which a muscle attaches to the skin, a bone, or another muscle. The insertion attaches to the structure that will be moved by the contraction of the muscle. Insertions are usually connections of muscle via tendon to bone.
Major Artery:
Each muscle's blood supply is carried to by a major artery.
Neural Innervation:
Which nerves innervate each muscle.
Trigger Points:
Hyperirritable spots in skeletal muscle that are associated with palpable nodules in taut bands of muscle fibers.
Physiology
Concentric Functions:
The function of a specific muscle while it is in its shortening phase.
Eccentric Functions:
The function of a specific muscle while it is in its lengthening phase
Isometric Function:
The function of a specific muscle while it is neither lengthening nor shortening.
Related Muscles:
Muscles which have similar structure or perform similar functions.
Antagonist:
Muscles which directly oppose the action of the listed muscle.
Exercises:
Exercises which recruit the muscle in question.
