Flashcards in nerve Deck (35):
1

includes brain and nervous system

central nervous system

2

all nerves that branch off spinal cord and brain

peripheral nervous system

3

shallow grooves separating gyri

sulcus

4

mostly for memory

Hippocampus

5

separates temporal lobe from frontal lobe

lateral sulcus

6

3 parts (medulla, pons, mid brain)

brain stem

7

folds in brain

gyrus

8

emotions

lymbic system

9

cuts brain into left and right hemispheres

longitudinal fissure

10

controls eyes response to light and movement

mid brain

11

understanding language( formulating thoughts and feelings into words)

wernickes area

12

precise motor control; little part on end of brain

cerebellum

13

whole brain

cerebrum

14

emotions, fear is a big one, emotions associate with memory

amyglada

15

PNS glial cells

Schwann and satellite cells

16

inhibits pain and enhances pleasure

endorphin

17

produce cerebrospinal fluid

ependymal cells

18

activates muscles , REM sleep , and parasympathetic division

acetylcholine

19

do not transmit impulses, but assist neurons

glial cells

20

wrap around an axon and create myeline sheath; speeds up impulse

oligodendrocytes

21

form blood brain barrier , regulate brain fluid , replace damaged neurons

astrocyte

22

help creat mylenin sheath around axons

Schwann cells

23

lipid protein complex that supports, protects and insulates axon

myelin

24

transmitter responsible for mood and emotions (can lead to depression)

serotonin

25

gives high feeling ;blocks neuron from firing

dopamine

26

lobe responsible for sensory functions (shape/texture)

parietal lobe

27

lobe responsible for hearing, interpreting speech and language, and smell

temporal lobe

28

lobe responsible for personality, voluntary motor functions, communications , and concentration

frontal lobe

29

lobe associated with visual information and visual memories

occipital lobe

30

somatic sensory

info from skin muscles, joints and etc

31

transmits information from PNS to CNS

afferent

32

Info from internal organs

visceral sensory

33

fight or flight

sympathetic

34

transmits information from CNS to rest of body

efferent

35

rest and digest

parasympathetic
