What else can I help you with?
What muscle is only responsible for elbow flexion?
The biceps brachii muscle is primarily responsible for elbow flexion. It crosses both the shoulder and elbow joints and is a strong supinator of the forearm.
What muscle is the primary mover for elbow flexion?
brachialis
What are 3 actions of the biceps muscle?
Elbow flexion, shoulder flexion and supination of the forearm.
What is the Antagonist for the Brachioradialis?
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.
Prime mover for shoulder flexion?
Prime mover is the bicep and the antagonist is the tricep.
What kind of muscle not responsible for flexion or extension of the arm?
The supinator muscle is a muscle in the forearm that is not directly responsible for flexion or extension of the arm. Its primary function is to rotate the forearm in a movement called supination, where the palm faces up.
What is the term for the muscle that bends and flexes the elbow joint?
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.
What is the muscles that rotate the radius without producing either flexion or extension of the elbow?
The muscle has to have origin and insertion below the elbow. There is only one such muscle. It is called as pronator quadtatus.
Term for the triceps brachii during elbow flexion?
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.
Which muscle does NOT flex the elbow?
The triceps brachii muscle does not flex the elbow; it is responsible for extending the elbow joint when it contracts.
What does the bachioradialis muscle do?
It does flexion of the elbow, in neutral, and also does pronation and supination, in order to return the arm to neutral
When does the bicep muscle make a prominent bulge?
In hyper flexion of elbow, I hope you are refering to biceps brachii
