Question

true or false question

neck muscles are innervated by spinal nerves.

true
false

Explanation:

Analyze the statement

Using the Muscle Innervation knowledge point

The statement asserts that neck muscles are innervated by spinal nerves.

Evaluate the anatomical innervation of neck muscles

Using the Muscle Innervation knowledge point

Most neck muscles (such as the infrahyoid muscles, scalenes, and splenius muscles) are innervated by cervical spinal nerves (C1–C8) via the cervical plexus and posterior rami. While some neck muscles like the sternocleidomastoid and trapezius receive motor innervation from cranial nerve XI (accessory nerve), the statement that neck muscles are innervated by spinal nerves is fundamentally true because the vast majority of the neck musculature relies on spinal nerve branches for motor and sensory function.

Answer:
