Question

While watching the Cubs lose again, Jacob decided to punch a hole through a sliding glass door in his kitchen. In doing so, he tore through some of the muscles on his anterior hand.

What muscles might he have injured?

Answer 1

Jacob may have injured the anterior compartment muscles of his hand, such as the thenar muscles, lumbrical muscles, and the adductor pollicis, which can result in the need for medical intervention.

Step-by-step explanation:

When someone punches a hole through a glass door and injures their hand, they may have damaged the muscles on the anterior (palmar) aspect of their hand. The anterior compartment of the hand contains quite a few muscles that could be affected, such as:

• Thenar muscles, which are responsible for the movement of the thumb and include the opponens pollicis, the abductor pollicis brevis, and the flexor pollicis brevis.
• The lumbrical muscles that flex the metacarpophalangeal joints and extend the interphalangeal joints.
• The adductor pollicis, which is used to adduct the thumb.
• Other superficial muscles, including the palmaris brevis that help in skin movement and grip.

Severe injuries might also affect the deeper structures such as the flexor digitorum superficialis and flexor digitorum profundus, which flex the fingers. A hand injury involving these muscles may require medical attention, including surgery, physical therapy, and a period of recovery to regain full functionality.
