18

central nervous system made up by

brain and spinal cord

19

autonomic nervous system

receive signals and controls actions that are not consciously perceived or controlled

20

somatic nervous system

receive signals and controls actions which are consciously perceived or controlled

21

neurons

are excitable cells that transmit electrical signals

22

neuroglia

supporting cells that help neurons to function and thrive

23

Soma

cell body that contains the nucleus-interprets message

24

dendrites

bring messages to the neuron

Axon

carries messages away

26

synaptic knobs

parts of the axon that secrete neurotransmitters

27

ependymal cells

line the fluid-filled cavities and produce transport and circulate fluid surrounding brain and spinal cord

28

microglia cells

are phagocytic they defend against pathogens

29

astrocytes

regulate the transport of nutrients and waste to and from neurons

30

oligodendrocytes

cells that produce the myelin sheath in the central nervous system
