Anatomy And Physiology 141 Lab ARM Muscle Review Quiz

The question asks for a name, and the correct answer is "biceps brachii." The other options listed are extensor carpi ulnaris, extensor digitorum, triceps brachii, and palmaris longus, which are all different muscles. Therefore, the correct answer is the only one that matches the given criteria.

The pronator teres is a muscle located in the forearm that plays a role in pronating the forearm and hand. It originates from the medial epicondyle of the humerus and inserts onto the radius bone. When it contracts, it rotates the forearm inward, causing the palm to face downward. This muscle is important for activities such as turning a doorknob or using a screwdriver.

The correct answer is flexor carpi radialis because it is the only muscle listed that is responsible for flexing the wrist. The other muscles listed are involved in different actions such as flexing the elbow (biceps brachii, brachialis), extending the fingers (extensor digitorum), and pronating the forearm (pronator teres).

The correct answer is extensor digitorum. This muscle is responsible for extending (straightening) the fingers. The other muscles listed are involved in different movements of the forearm and wrist, but not specifically in extending the fingers.

The palmaris longus is a muscle located in the forearm. It is responsible for flexing the hand at the wrist joint. It runs from the elbow to the palm of the hand and helps with gripping and grasping objects. The other muscles listed are also located in the forearm, but they have different functions. The extensor carpi ulnaris extends the hand at the wrist, the brachioradialis flexes the forearm at the elbow, the pronator teres pronates the forearm, and the brachialis flexes the forearm at the elbow.

The given list consists of names of forearm muscles. Out of the given options, "brachioradialis" is the correct answer. The brachioradialis muscle is located in the forearm and is responsible for flexing the forearm at the elbow joint. It is a superficial muscle that runs along the radial side of the forearm. The other options listed are also forearm muscles, but they do not match the name "brachioradialis".

The brachialis is a muscle located in the upper arm, specifically in the anterior compartment. It lies deep to the biceps brachii muscle and is responsible for flexing the forearm at the elbow joint. The other muscles listed, such as biceps brachii, palmaris longus, pronator teres, and flexor carpi radialis, are also muscles in the upper arm and forearm, but they have different functions and locations compared to the brachialis muscle.

The given list consists of names of muscles in the forearm. The correct answer, extensor carpi ulnaris, is a muscle located on the posterior side of the forearm. It is responsible for extending and adducting the wrist. The other muscles listed in the question also exist in the forearm, but they have different functions and locations.

The given list consists of different muscles in the forearm. The palmaris longus, brachioradialis, extensor carpi ulnaris, pronator teres, and flexor carpi ulnaris are all muscles in the forearm. Out of these options, the flexor carpi ulnaris is the correct answer. It is a muscle located on the inner side of the forearm and is responsible for flexing the wrist and adducting the hand.
