Final answer:
In the peripheral nervous system, the connective tissue amount surrounding nerves is greater than that around the nerve roots, with three types of connective tissue layers protecting and nurturing the nerves: epineurium, perineurium, and endoneurium.
Step-by-step explanation:
The amount of connective tissue surrounding the nerves in the periphery is comparatively greater than the amount surrounding the nerve roots. In the peripheral nervous system (PNS), nerves consist of several types of connective tissue. The outermost layer is the epineurium, which is a fibrous connective tissue. Each fascicle within the nerve is surrounded by its own fibrous connective tissue, known as the perineurium, and individual axons within these fascicles are in turn enveloped by a loose connective tissue called the endoneurium. These layers provide protection and nourishment to the nerves and differ from the connective tissue found in the central nervous system (CNS).
