Answer 1

1.

Biceps. The muscles at the front of your upper arm. You use these when you bend your arm or pick things up.

The moveable end of the muscle that attaches to the bone being pulled is called the muscle’s insertion, and the end of the muscle attached to a fixed (stabilized) bone is called the origin.

Although a number of muscles may be involved in an action, the principal muscle involved is called the prime mover, or agonist. During forearm flexion, for example lifting a cup, a muscle called the biceps brachii is the prime mover. Because it can be assisted by the brachialis, the brachialis is called a synergist in this action. A synergist can also be a fixator that stabilizes the muscle’s origin.

A muscle with the opposite action of the prime mover is called an antagonist. Antagonists play two important roles in muscle function: (1) they maintain body or limb position, such as holding the arm out or standing erect; and (2) they control rapid movement, as in shadow boxing without landing a punch or the ability to check the motion of a limb.

The medial half (acts on the little and ring fingers) is innervated by the ulnar nerve. The lateral half (acts on the middle and index fingers) is innervated by the anterior interosseous branch of the median nerve.

2.

deltoid anterior (DA) and gastrocnemius medialis (GM)

The three main elbow flexors, i.e. the brachialis, biceps brachii and brachioradialis muscles, and the triceps brachii muscle show some activity during driving, but without any meaningful correlation between the periods of activity and the deviation of the steering wheel.

Agonist - deltoid anterior

Anatgonist- gastrocnemius medialis

The medial half (acts on the little and ring fingers) is innervated by the ulnar nerve. The lateral half (acts on the middle and index fingers) is innervated by the anterior interosseous branch of the median nerve.
