The nervous system

BBB 1.2-1.3b

inter-neurons

Neurons within the brain and spinal cord; they communicate internally and process information between the sensory inputs and motor outputs.

Motor (efferent) neurons

Neurons that carry outgoing information from the brain and spinal cord to the muscles and glands

sensory (afferent) neurons

neurons that carry incoming information from the body’s tissues and sensory receptors to the brain and spinal cord

nerves

bundled axons that form neural cables connecting the central nervous system with muscles, glands and sensory organs

PNS (peripheral nervous system)

the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body

CNS centeral nervous system

the brain and spinal cord

Nervous system

the body’s speedy, electro-chemical communication network, consisting of all the nerve cells of the peripheral and centeral nervous system
