PATHOLOGY

Detailed explanation-1: -Ganglia are collections, or small knots, of nerve cell bodies outside the CNS. The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division. The afferent or sensory division transmits impulses from peripheral organs to the CNS.

Detailed explanation-2: -The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS. There are three layers of meninges around the brain and spinal cord.

Detailed explanation-3: -Your somatic nervous system is a subdivision of your peripheral nervous system that stretches throughout nearly every part of your body. The nerves in this system deliver information from your senses to your brain. They also carry commands from your brain to your muscles so you can move around.

Detailed explanation-4: -The motor division of the PNS carries nerve impulses from the central nervous system to muscles and glands throughout the body.
