Which of the following muscles is innervated by the median nerve?

• A. Flexor carpi ulnaris
• B. Deep digital flexor
• C. Triceps
• D. Superficial gluteal

Answer: (B)

The muscle that is innervated by the median nerve among the options is the deep digital flexor. This muscle plays a significant role in flexing the digits and is crucial for fine motor control of the paw. The median nerve is primarily responsible for innervating muscles of the forearm that are involved in flexion and pronation.

In contrast, the flexor carpi ulnaris is innervated by the ulnar nerve, highlighting its distinction from muscles that the median nerve controls. The triceps muscle, responsible for extending the elbow, is innervated by the radial nerve, and the superficial gluteal muscle, associated with hip extension and abduction, receives its nerve supply from the gluteal nerves. Understanding the specific innervations of these muscles is important for grasping the overall function of the nervous system in relation to muscle action.
