10

Motor Cortex

Precentral Gyrus

11

Somatic Sensory Cortex

Postcentral Gyrus

12

Wernicke's area

Language processing

13

Broca's area

Produces speach

14

Aphasia

Language disorder that affects a persons ability to communicate

15

Unipolar Nerve Cell

Cell body at one end
Axon and dentrites on the other

16

Bipolar Nerve Cell

Dendrites then cell body then axon

17

Pseudounipolar Nerve Cell

Dendrites then uninterrupted axon with cell body sprout

18

Oligodendrocyte

Support cell of the CNS myelinates multiple nerve cells

19

Schwann Cell

Support cell of the PNS myelites by wrapping nerve

20

Protoplasmic Astrocyte

Found in gray matter
Sheet like appendages

21

Fibrous Astrocyte

Found in white matter
Long, fine processes that contain intermediate filaments

22

Microglia

Immune system cells of the NS

23

Macroglia

Oligodendrocytes
Schwann Cells
Astrocytes

24

Regions of a nerve cell

Input Region
Integrative Region
Conductive Region
Output Region

25

Feed Forward Inhibition

Enhances effect of pathway by suppressing opposite affect

26

Feedback Inhibition

Self Regulation effect that turns off effect at the same time as causing it

27

Plasticity

Short term physiological changes can change the effectiveness of a synapse
