Identify a true statement about the peripheral nervous system (PNS).

A. It consists of cranial and spinal nerves that spread throughout the body.

B. It constitutes the upper and lower extremities of the body along with the shoulder and pelvic girdles.

C. It supports, protects, and allows bodily movement.

D. It provides the shape and form of the human body.

Answer: A. It consists of cranial and spinal nerves that spread throughout the body.

Explanation:

The peripheral nervous system (PNS) is made up of all nerves outside the central nervous system (CNS); includes all the cranial nerves that carry impulses to and from the brain and all the spinal nerves that carry messages to and from the spinal cord. This includes long nerve fibers as well as ganglia made of neural cell bodies. The peripheral nervous system connects the central nervous system (CNS) to various parts of the body.

The part of the body that constitutes the upper and lower extremities of the body along with the shoulder and pelvic girdles is the appendicular skeleton.

The part of the body that supports, protects, and allows bodily movement is the skeleton. The skeleton also provides the shape and form of the human body.
