consists of the brain and spinal cord

• autonomic nervous system (ANS)
• Central Nervous System (CNS)
• Peripheral Nervous System (PNS)
• Somatic Nervous System (SNS)

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

• Somatic Nervous System (SNS)
• Central Nervous System (CNS)
• Peripheral Nervous System (PNS)
• autonomic nervous system (ANS)

Individual cells in the nervous system that receive, integrate, and transmit information.

• Axon
• Myelin
• Dendrites
• Neurons
