Peripheral Nervous System (PNS)
–Consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves.
– Serves as a critical link between the body and the central nervous system.
– peripheral nerves contain an outermost layer of fibrous connective tissue called epineurium which surrounds a thinner layer of fibrous connective tissue called perineurium (surrounds the bundles of nerve or fascicles). Individual nerve fibers within the nerve are surrounded by loose connective tissue called endoneurium.
