GENERAL HISTOLOGY

Detailed explanation-1: -Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.

Detailed explanation-2: -Relay neurons are found in the brain and spinal cord and allow sensory and motor neurons to communicate. Motor neurons are found in the central nervous system (CNS) and control muscle movements.

Detailed explanation-3: -The spinal nerves contain the fibers of the sensory and motor neurons. A nerve does not contain cell bodies. They are located in the ganglion (sensory) or in the gray matter (motor).

Detailed explanation-4: -The purpose of the spinal cord is to send motor commands from the brain to the peripheral body as well as to relay sensory information from the sensory organs to the brain.
