The Spinal Cord is the thick column of nerve tissue that links the brain to most of the nerves.

The thick bundle of nerve fibers through which the brain communicates with the body is the spinal cord.
The epineurium is the outermost layer of connective tissue surrounding a nerve. In the case of the fibrous sheath, the epineurium refers to the thick layer of dense connective tissue that surrounds and protects the entire nerve bundle, providing structural support and protection.
The human scalp is about 5-6 millimeters thick on average. It is the thickest skin on the body and consists of several layers, including the epidermis, dermis, and subcutaneous tissue.
Collagenous fibers are the tough fibers of connective tissue.
Yes, but it is very different from the humans brain because it does not feel pain.
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.
Nerves vary in size. Nerves like the sciatic nerve are large while other are small. There are three types of nerves in the human body. Afferent, efferent, and mixed.
