A tough band of fibrous connective tissue that usually connects muscle to bone.
The fixed, non-moveable end of a skeletal muscle
The fixed, moveable end of a skeletal muscle.
An area where two or more bones come together.
When an opposing muscle on the opposite side of a joint contracts to create an opposing movement to its muscle counterpart (example flexion vs. extension).
When a group of muscles work together to create the same movement; an example would be your bicep brachii and brachialis muscle contraction simultaneously to create flexion (bending) of your elbow.
The nervous system controlling muscle groups that oppose and work against one another; allows for a variety of movements and protection of joints.
