Flashcards in Parts and Functions of the Brain Deck (38):
1

Cerebral Cortex function

complex perceptual, cognitive, and behavioral process

2

Basal Ganglia function

movement

3

Limbic System function

emotion(aggression, fear, pleasure, and pain) and memory

4

Thalamus function

sensory relay system - Except for

5

Hypothalamus function

hunger and thirst, emotion

6

Inferior colliculus function

sensorimotor reflexes; receives sensory information from the auditory system
role in reflexive reactions to sudden loud noises

7

Superior Colliculus function

sensorimotor reflexes; receives visual sensory input

8

Cerebellum function

refined motor movements

9

Medulla Oblongata function

vital functioning (breathing, digestion)

10

Reticular Formation function

arousal and alertness

11

Principle structures of the Forebrain

Cerebral cortex
Basal ganglia
limbic system
thalamus
hypothalamus

12

Principle structures of the midbrain

inferior and superior colliculi

13

Principle structure of the Hindbrain

cerebellum
medulla oblongata
reticular formation

14

Brainstem is

hindbrain and midbrain

15

limbic system is what

a group of neural structures primarily associated with emotion and memory

16

cerebral cortex is what

outer covering of the cerebral hemispheres

17

brain develops from

neural tube

18

3 swellings of neural tube

prosencephalon-forebrain
mesencephalon-midbrain
rhombencephalon-hindbrain

19

5 swelling of neural tube

telencephalon
diencephalon
mesencephalon-midbrain
metencephalon
myelencephalon

20

hindbrain functions

controls balance
motor coordination
breathing
digestion
general arousal-sleeping and waking
vital functions for survival

21

medulla oblongata from

myelencephalon from rhombencephalon

22

pons and cerebellum from

metencephalon from rhombencephalon

23

medulla oblongata function

regulating vital functions -
breathing
heart rate
blood pressure

24

pons location

above the medulla

25

pons function

sensory and motor pathways between the cortex and the medulla

26

cerebellum location

top of hindbrain mushrooming out of the back of the pons

27

cerebellum function

maintain posture and balance
coordinates body movements

28

damage to cerebellum would cause

clumsiness
slurred speech
loss of balance

29

midbrain is from

mesencephalon

30

midbrain function

receives sensory and motor information from the rest of the body
associated with involuntary reflex responses triggered by visual or auditory stimuli

31

prominent features of the midbrain

nuclei

32

prominent nuclei of the midbrain

superior colliculus
inferior collicullus

33

forebrain is from

prosencephalon

34

telencephalon forms what parts

cerebral cortex
basal ganglia
limbic system

35

diencephalon forms what parts

thalamus
hypothalamus
posterior pituitary gland
pineal gland

36

forebrain associated with what processes

complex perceptual
cognitive
behavioral
emotion and memory

37

what part has the greatest influence on human behavior

forebrain

38

forebrain functions necessary for survival?

not absolutely necessary for survival
