Question: 1 / 400

Which muscle turns the palm of the hand upwards?

Flexor Ulnaris

Abductor

Supinator

The other options are incorrect because

A: Flexor Ulnaris is a muscle located in the forearm responsible for flexing the wrist and adducting the hand. It does not affect the rotation of the palm.

B: Abductor is a muscle that moves a body part away from the midline of the body, not relevant to the rotation of the palm.

D: Opponens is a muscle located near the thumb and is responsible for opposing the thumb to the other fingers, not involved in palm rotation.

Supinator, however, is a muscle located in the upper arm and forearm responsible for turning the palm of the hand upwards (or supination). This muscle works in conjunction with the pronator teres, a muscle that rotates the palm downwards.
