The "middle" part of a muscle is the muscle belly. For instance, the peak of the biceps is the belly of that muscle - it is the part of the biceps musculotendinous unit that can be contracted, as in "make a muscle" when flexing the biceps. Musculotendinous unit: A muscle is anchored at both ends, usually by tendons, so that when a muscle is flexed or shortened concentrically, the muscle fibers pull closer together and the tendons pull on the bones that they are attached to, closing the joint angle that the muscle affects - in this case, bringing the forearm closer to the upper arm, decreasing the joint angle at the elbow.

What is the difference between muscle flexing and and muscle extension?
when u flex it, it tightens, when u extend it, it stretches Flexion is when a muscle action decreases the angle at a joint, extension is when the angle increases. A simple example is bicep curl, flexion is when the hand is brought up towards the shoulder, decreasing the angle at the elbow joint. Just because a muscle is performing flexion or extension does not not mean it is contracting or stretching, that is eccentric and concentric movement. A muscle can still be tight when performing extension.
