Question

The biceps brachii is responsible for which of the following movements?

A. Flexes the arm at the elbow joint
B. Supinates the forearm at the elbow joint
C. Supinates the hand at the elbow joint
D. All of the above

Answer 1

D, because it basically moves everything in your arm if you think about it

Answer 2

The brachial biceps is responsible for supination of the forearm at the elbow joint (option B).

Step-by-step explanation:

Brachial biceps muscle consisting of two parts and is located in the anterior region of the arm, accompanied by the anterior brachial and coracoides muscles.

Biceps is the main flexor of the elbow joint, bringing the forearm closer to the arm. In addition, with the elbow fixed, it is responsible for the supination of the forearm. Other movements it performs are the anterior flexion of the shoulder joint and the abduction of the upper limb.

The other options are not correct because:

A. The biceps flexes the elbow joint, not the arm.

C. The supination of the hand depends on the supination of the forearm.
