Central nervous system(CNS)

The brain and spinal cord

15

Peripheral nervous system(PNS)

All neural tissue outside the central nervous system

16

Somatic nervous system(SNS)

Division of the PNS that controls skeletal muscle contractions

17

Automatic nervous system(ANS)

Division of the PNS that is controlled subconsciously

18

Sympathetic nervous system(TNS)

Division of the ANS involved in the "fight-or-flight" response
(Thoracolumbar nervous system)

19

Parasympathetic nervous system

Division of the ANS involved in the "rest-and-digest" response
(Craniosacral nervous system)

Sensory function

Using receptors to detect changes and respond in order to maintain homeostasis

21

Special senses

The five senses of olfaction gustation, vision equilibrium, and hearing

22

Neurons

Nerve cells that send and receive nerve impulses

23

Cell body

The main part of a neuron

24

Axon

Nerve cell extension that carries impulses away from the cell body

25

Dentrities

Branched nerve extensions that carry impulses towards the cell body

26

Myelin

White, fatty substance that forms an insulating sheath around axons

27

Synapses

Sites when adjacent neurons communicate

28

Neurotransmitters

Chemical messengers between neurons or between neurons and muscles

29

Neuroglia

Supporting cells of the CNS and PNS

30

White matter

Regions in the CNS dominated by the myelinated axons
