Explanation / Answer

Ans: All the fill in the blanks is in capital letters.

One end of a skeletal muscle attaches to a relatively immovable point called it's ORIGIN and the other end attaches to a more movable point called the INSERTION.

The location of these attachment points determine the type of movement that occurs at a JOINT.

Consider the elbow joint. Muscles such as the BICEPS BRACHII have their origin and insertion on the anterior of the arm.Thus contraction of this muscle causes FLEXION of the elbow joint.

In contrast contraction of the TRICEPS BRACHII located on the Posterior aspect of the arm will cause EXTENSION of the elbow joint.
