Question

The important muscles ( APB, opponens pollis bravis, and flexor pollis brevis) innvervated by the median nerve in the hand and collectively are called the ________ muscles

Answer 1

The abductor pollicis brevis, opponens pollicis brevis, and flexor pollicis brevis are innervated by the median nerve and collectively known as the thenar muscles.

Step-by-step explanation:

The important muscles innervated by the median nerve in the hand are the abductor pollicis brevis (APB), opponens pollicis brevis, and flexor pollicis brevis, and collectively, these are called the thenar muscles. The thenar muscles are located on the lateral part of the palm and are responsible for the thumb's movement, forming the thenar eminence - the rounded contour of the base of the thumb. These muscles are essential for precise movements such as typing and writing, as they allow complex maneuvers of the thumb essential for grip and dexterity.
