to flex the forearm at the elbow, you use the biceps brachii, brachialis, and brachioradial (to a lesser extent).
to supinate the forearm, you use the biceps brachii and the supinator muscles.
the biceps brachii does both motions.

What is the action of the biceps brachii?
-Flexion of the Arm -Flexion of the Forearm-Supination of the Forearm-Stabilization of the glenohumeral joint
Which muscles contract when forearm is flexed at the elbow?
Both the tricep and the bicep are muscles which control rotational movement at the elbow. The bicep contracts when the forearm is flexed, and the tricep contracts when the forearm is extended.
Is brachialis a muscle in the arm?
The brachialis is a muscle in the upper arm that flexes the elbow joint.
What is an anconeus?
An anconeus is a muscle of the elbow and forearm.
What is anconeus?
An anconeus is a muscle of the elbow and forearm.
What muscle flexes the elbow but neither originates nor inserts on the humerus?
The biceps brachii muscle.
What happens to the biceps when muscle contracts?
When a bicep contracts it pulls on tendons causing the arm to bend at the elbow.
What muscle extends the forearm?
Triceps Brachii extends the forearm at the elbow joint.
What muscle flexes the elbow and attaches the the ulna?
The triceps and the brachialis both attach to the ulna.
Name the prime mover that flexes the forearm at the elbow?
It's bicep muscle.Actually its the Brachialis muscle that is the prime mover to flex the upper limb at the elbow. The biceps brachi (leymen: biceps) is only a helper and only when the arm is suppinated, suppination being the biceps primary function. Technically the arm is only the region of the upper limb between the shoulder and the elbo and thus flexion of the arm actually means lifting the humerus up and forwards. The muscles that contribute to this movement are the Clavicular part of the deltoid, clavicular head of pectoralis major, and there is a slight input from coracobrachialisNO the biceps muscle flexes the forearm (the elbow joint). The Pectoralis major is the prime mover of arm flexion. I am getting this right out of my lab book.
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 definition of brachioradialis?
The brachioradialis is a muscle found in the forearm that helps flex the forearm at the elbow. It is capable of pronation and supination.
