What is the function of the connective tissue wrappings in a nerve?

Answer 1

Peripheral nerve axons and their supporting Schwann cells are held together by connective tissue forming nerve fibers. The connective tissue of nerves has three distinct components - endoneurium, perineurium, and epineurium. Endoneurium is a thin layer of connective tissue associated with individual axons. Perineurium surrounds small groups of axons (each wrapped in endoneurium) called fascicles that conduct similar types of information or arise from a specific anatomic region of the body. The epineurium is a layer of dense connective tissue that surrounds and binds together many nerve fascicles into a common bundle.

Central nervous system - The brain and spinal cord are enclosed within three sequential connective tissue membranes called meninges. The innermost layer resting directly on the surface of the brain and spinal cord is called the pia mater. The outermost layer is a relatively thick sheet of dense connective tissue called the dura mater. The delicate arachnoid mater is attached to the inner surface of the dura and extends to the pia mater on the surface of the brain and spinal cord. The loose organization of the arachnoid produces a space containing cerebrospinal fluid called the subarachnoid space. Cerebral vessels course through the subarachnoid space.

Answer 2

The myilen sheath helps conduct the nerve impulse kind of like water and electricity.

Answer 3

Mostly support and protection, as well as insulation against temperature extremes.

Answer 4

Endoneurium....

Answer 5

Epineurium
