Fabric Nervous

Nervous tissue (Latin Fabrica nervosa) is a Latin neologism meaning “factory of nerve cells.” Literally, nervous tissue means “nerve tissue.”

Translated into Russian, the word nervous means “containing nerve cells.” Nerves are specialized endings of the peripheral nervous system. Nerve fibers carry impulses between the central nervous system and all tissues of the body. Therefore, nervous tissue is part of both the central and peripheral nervous systems.

Nervous tissue within organs forms: central (brain and spinal cord), peripheral (cranial, spinal, sympathetic, parasympathetic) and autonomic nerves. The nerves leaving the brain and spine are called central (we will not include the very thin vagus and connecting nerves). Peripheral nerves consist of an axial trunk and peripheral fibers (myelinated and unmyelinated nerve fibers). Nerves have myelinated or unmyelinated sheaths, as well as fibers that unite
