What is the primary function of the perineurium?
Understand the Problem
The question is asking for the primary function of the perineurium, which is a specific protective layer surrounding nerve fibers. It presents multiple-choice options to select the correct answer regarding its role.
Answer
The perineurium protects peripheral nerves and maintains structural and functional integrity.
The primary function of the perineurium is to maintain the structure and function of the peripheral nervous system by acting as a protective connective tissue sheath that surrounds peripheral nerves and to function as a barrier to maintain homeostasis of the endoneurium.

The primary function of the perineurium is to maintain the structure and function of the peripheral nervous system by acting as a protective connective tissue sheath that surrounds peripheral nerves and to function as a barrier to maintain homeostasis of the endoneurium.
More Information
The perineurium not only provides protection and structural integrity to nerve fibers but also serves as a diffusion barrier, helping to control the environment around the nerve cells and maintaining internal pressure within the nerve.
