Flashcards in Ch 15 Lec 3 - Human Brain Deck (45):
1

part of the mesencephalon that has the superior and inferior colliculi

corpora quadrigemina

2

receives visual input from thalamus in corpora quadrigemina

superior colliculi

3

receives auditory input from medulla in the corpora quadrigemina

inferior colliculi

4

rounded bulge on the underside of the brain stem

pons

5

pons separates blank from blank

midbrain, medulla

6

the pons is made of masses of blank matter and blank fibers

gray, nerve

7

pons blank impulses to and from blank and blank

relays, medulla, cerebrum

8

pons regulates blank

depth of breathing

9

this has two hemispheres and is below the cerebrum

cerebellum

10

two hemispheres of cerebellum are separated by blank and connected by blank

falx cerebelli, vermis

11

the cerebellum is mainly blank matter and is controlled by the blank

white, arbor vitae

12

cerebellum integrates blank information about the blank of body parts

sensory, position

13

cerebellum coordinates blank activities

muscle

14

cerebellum fine tunes blank and blank movements

voluntary, involuntary

15

this is a point of connection for several cranial nerves and goes from the foramen magnum to the pons

medulla oblongata

16

oval swellings of medulla oblongata

olivary nucleus

17

two reflex centers of the medulla oblongata

cardiovascular center, respiratory rhythmicity center

18

reflex center of medulla that adjusts blood flow and heart rate

cardiovascular center

19

reflex center for basic pace of respiratory movements in medulla

respiratory rhythmicity center

20

network of nerve fibers associated with islands of gray matter

reticular formation

21

reticular formation blank areas with fibers in all major tracts

interconnects

22

reticular formation regulates these motor activities

sleep, wakefullness

23

inc activity means

wakefulnesss

24

dec activity means

sleep

25

nuclei and tracts along the border of cerebrum and diencephalon

limbic system

26

three parts of cerebrum are part of the limbic system

limbic lobe, hippocampus, amygdaloid body

27

deep to all other lobes and is part of limbic system

limbic lobe

28

nucleus within limbic lobe

hippocampus

29

the limbic system establishes blank states and related blank drives

emotional, behavioral

30

limbic system links intellectual functions of blank to unconscious functions of blank brain

cortex, lower

31

the limbic system facilitates blank storage

memory

32

there are 12 blank nerves

cranial

33

all cranial nerves originate from the blank except the first pair

brain stem

34

cranial nerve for smell and passes through the blank

olfactory, cribriform plate

35

cranial nerve for vision and passes through the optic blank

vision, foramina

36

cranial nerve that moves the majority of eye muscles

oculomotor

37

cranial nerve that is the smallest pair and controls superior oblique muscles of eye only

trochlear

38

cranial nerve that is the largest and has three branches that controls face, pallet, eye, teeth

trigeminal

39

cranial nerve that controls the lateral rectus eye muscles only and comes from pons

abducens

40

cranial nerve that comes from pons and has taste receptors on tongue and has muscles for facial expression

facial

41

cranial nerve that comes from the auditory nerve from the medulla and has two parts that is sensitive to position of head and is interpreted as hearing

vestibulocochlear

42

cranial nerve that helps swallowing

glossopharyngeal

43

cranial nerve that is from medulla to chest and abdomen and is for speech and swallowing and controls the heart, lungs, esophagus (viscerals)

vagus

44

cranial nerve with two branches that controls musculature of throat

accessory

45

cranial nerve that also controls tongue and neck musculature and near chin

hypoglossal
