ANATOMY

Detailed explanation-1: -The nervous system uses electrical and chemical means to help all parts of the body to communicate with each other. The brain and spinal cord make up the central nervous system. Nerves everywhere else in the body are part of the peripheral nervous system.

Detailed explanation-2: -The peripheral nervous system (PNS), which consists of the neurons and parts of neurons found outside of the CNS, includes sensory neurons and motor neurons. Sensory neurons bring signals into the CNS, and motor neurons carry signals out of the CNS.

Detailed explanation-3: -Nervous tissue, present in both the CNS and PNS, contains two basic types of cells: neurons and glial cells.

Detailed explanation-4: -The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

Detailed explanation-5: -Neuronal cell body of a sensory afferent is not part of the central nervous system. Sensory afferent nerves are located in the peripheral nervous system. They work to perceive stimuli and convert those perceptions to impulses that are sent towards the spinal cord where they are then sent towards the brain for analysis.
