Question

multiple choice question
what areas of the body do the cervical plexuses innervate?
○ skin and muscles in the trunk
○ skin and muscles of the lower limb
○ skin and muscles of the neck
○ skin and muscles of the upper limb

Explanation:

The cervical plexuses are a network of nerves originating from the cervical spinal nerves. Their primary function is to innervate the skin and muscles of the neck region. The trunk is innervated by other nerve plexuses (like the thoracic nerves), the lower limb by the lumbosacral plexus, and the upper limb by the brachial plexus. So the correct option is the one related to the neck.

Answer:

C. Skin and muscles of the neck
