GENERAL HISTOLOGY

Detailed explanation-1: -The spinal nerves emanate from the spinal cord as pairs of nerves composed of both sensory and motor fibers that function as the intermediary between the central nervous system (CNS) and the periphery.

Detailed explanation-2: -1 Spinal nerves. The spinal nerves consist of 31 symmetrical pairs of nerves that connect the spinal cord to the periphery. There are 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal nerves.

Detailed explanation-3: -At the base of the brain, the brain stem connects to the spinal cord and is made up of the midbrain, pons, and medulla oblongata.

Detailed explanation-4: -The brachial plexus begins in the spinal cord at the cervical and upper thoracic region (from C5-T1) and is a system of nerves that relays messages to and from the central nervous system to your shoulder, arm and hand. If this web of nerves is damaged, it can have potentially severe consequences.
