Module 1 Terminology

Question 1

Central Nervous System (CNS)

Answer 1

Consists of the brain and spinal cord (brainstem and cerebellum included)

Question 2

Peripheral Nervous System (PNS)

Answer 2

All neurons outside of or peripheral to the central nervous system divided into the somatic and autonomic systems

Question 3

Somatic Nervous System

Answer 3

Part of the peripheral nervous system associated with the innervation of sensory organs and the voluntary control of body movements via skeletal muscles

Question 4

Autonomic system

Answer 4

The part of the peripheral nervous system associated with the innervation of viscera that operates largely below the level of consciousness

Question 5

Sensory neurons

Answer 5

Receive stimulation from the periphery and transmit the information to the CNS

Question 6

Interneurons

Answer 6

Receive either sensory or motor info and pass that info to other neurons: only in CNS

Question 7

Motor neurons

Answer 7

Receive stimulation from the CNS and then project to a muscle or gland

Question 8

Afferent neurons

Answer 8

Sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system

Question 9

Efferent neurons

Answer 9

Motor neurons that carry neural impulses away from the central nervous system and towards muscles to cause movement
