Nervous tissue, also called neural tissue, is the main tissue component of the nervous system.The nervous system regulates and controls body functions and activity. It consists of two parts: the central nervous system (CNS) comprising the brain and spinal cord, and the peripheral nervous system (PNS) comprising the branching peripheral nerves.

A nerve transmits electrical impulses and is the basic unit of the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses called action potentials that are transmitted along each of the axons to peripheral organs or, in the case of sensory nerves, from the periphery back to the central nervous system.
A nerve is an enclosed, cable-like bundle of nerve fibers (called axons) in the peripheral nervous system. Nerves have historically been considered the basic units of the peripheral nervous system. Nerves have historically been considered the basic units of the peripheral nervous system.
The nervous system consists of nervous tissue which, at a cellular level, is defined by the presence of a special type of cell, called the neuron. Neurons have special structures that allow them to send signals rapidly and precisely to other cells.

Neuropathology is the study of disease of nervous system tissue, usually in the form of either small surgical biopsies or whole-body autopsies. Neuropathologists usually work in a department of anatomic pathology , but work closely with the clinical disciplines of neurology , and neurosurgery , which often depend on neuropathology for a diagnosis.
This nerve movement also applies to the spinal nerves, which can stretch and slacken with movement of the spine. [4] This nerve gliding happens at intraneurial and extraneurial tissue planes. Outside the nerve, a thin layer of tissue similar to adventitia surrounds the nerve upon which the epineurial surface glides. Inside the nerve, fascicles ...
