brachialis, brachioradialis, biceps brachii
Bicep brachii, especially in supination, brachioradialis( when the forearm is in neutral-thumb facing up), and brachialis, especially when the arm is pronated.
brachii and brachioradialis
The bicep
The bicep
brachialis
Elbow flexion, shoulder flexion and supination of the forearm.
The antagonist for the brachioradialis muscle is the pronator teres. It helps to produce opposite movements at the elbow joint, with the brachioradialis mainly responsible for elbow flexion and the pronator teres for elbow extension.
Which of these muscles is not responsible for flexion or extension of the arm?
Flexion (same as bending) at the elbow joint (between the humerus and the radius and ulna) is mainly achieved by the Brachialis Muscle. This is not the answer most would expect as everyone knows the Biceps Brachii (Biceps of the arm) are what flexes this joint. In fact the biceps does both supination and flexion of the elbow because its insertion is on the radius. Only when the forearm is supinated, the biceps is able to assist the deeper and more powerful brachialis muscle with the flexion of the elbow.
Thie brachialis is a muscle in the arm of the upper limb and it is the primary flexor of the elbow joint.
The muscle has to have origin and insertion below the elbow. There is only one such muscle. It is called as pronator quadtatus.
Triceps brachiiElbow flexion is due to the contraction of the biceps brachii, the prime mover. The triceps brachii extends as the biceps brachii contracts and therefore is the antagonist muscle.
shoulder
It does flexion of the elbow, in neutral, and also does pronation and supination, in order to return the arm to neutral
In hyper flexion of elbow, I hope you are refering to biceps brachii
