Flashcards in Ch 15 Lec 1 - Human Brain Deck (61):
1

regions of the brain

cerebrum, diencephalon, mesencephalon, cerebellum, pons, medulla oblongata

2

unconscious coordination of the brain

cerebellum

3

region of brain that controls rhythms and sleep patterns

pons

4

region of the brain that regulates cardio function, respiratory function, digestive function

medulla oblongata

5

the brain has blank similar to spinal cord

meninges

6

outer most layer of the brain and forms the internal blank of the skull

dura mater, periosteum

7

there is no blank in the meninges of the brain

epidura

8

partitions of the dura mater in the brain

falx cerebelli, falx cerebri, tentorium cerebelli

9

dura mater partition that separates right and left cerebellar hemispheres

falx cerebelli

10

dura mater partition that separates right and left cerebral hemispheres

falx cerebri

11

dura mater partition that separates lobes of cerebrum from cerebellum

tentorium cerebelli

12

has a blank and blank mater like spinal cord

pia, arachnoid

13

ventricles of the brain are spaces filled with blank

csf

14

there are two blank ventricles of the brain

lateral

15

2 lateral ventricles of brain are connected to the third ventricle by blank

interventricular foramen

16

the blank ventricle of the brain is connected to the fourth ventricle by the blank

third, central canal

17

the blank ventricle connected to central canal of the blank

fourth, spinal cord

18

three functions of cerebrospinal fluid

cushions, transport nutrients, transport wastes, supports brain

19

csf comes from blank

the brain

20

csf is formed in blank in the brain

choroid plexus

21

lobes located in the ventricles of the brain that consist of ependymal cells and permeable capillaries

choroid plexus

22

csf is taken from the blank by blank cells and pooled in the ventricles

blood, ependymal

23

csf moves throughout the entire blank

central nervous system

24

csf moves through blank in the fourth ventricles to blank space

apertures, subarachnoid space

25

csf is around the blank

subarachnoid space

26

csf is reabsorbed in the blank

sagittal sinus

27

large venous tube within the dura mater

sagittal sinus

28

sagittal sinus extends along the midline of the blank

cerebral hemispheres

29

arachnoid extends into sagittal sinus through blank

arachnoid granulation

30

in the sagittal sinus, csf goes back to blank

the blood

31

three functions of cerebrum

interpret sensory impulses, voluntary muscle movements, memory, reasoning process, intelligence, personality

32

cerebrum has two blank

hemispheres

33

two hemispheres of cerebrum are connected by blank

corpus callosum

34

two hemispheres of brain are separated by blank

longitudinal fissure

35

two hemispheres possess ridges (blank) and grooves (blank)

gyri, sulci

36

hemispheres of cerebrum receives blank and generates blank information to the blank side of the body

sensory, motor, opposite

37

hemispheres of cerebrum communicate by the blank

corpus callosum

38

cell somas of the cerebrum are located at outer regions of cerebral blank

lobes

39

cell somas of cerebrum are centralized in masses called blank

basal nuclei

40

cell somas are blank matter

gray

41

myelinated axons are blank matter

white

42

three types of cerebral white matter

commissural fibers, association fibers, projection fibers

43

cerebral white matter that connect corresponding gray areas on different hemispheres

commissural fibers

44

cerebral white matter that connect different parts of same hemisphere

association fibers

45

cerebral white matter that connect cerebrum to lower brain areas

projection fibers

46

these are named after the bone they are found under

cerebral lobes

47

four lobes of cerebrum

parietal, frontal, temporal, occipital

48

one cerebral lobe is blank

deep

49

the deep cerebral lobe

insula

50

cerebral lobes are separated by special blank

sulci

51

three sulci of cerebrum

central, lateral, parieto-occipital

52

cerebral sulcus that separates the frontal lobe from the parietal lobe

central sulcus

53

cerebral sulcus that separates the parietal lobe from the temporal and is the most obvious

lateral sulcus

54

cerebral sulcus that separates the parietal lobe from the occipital

parieto-occipital sulcus

55

region of the cerebrum that deals with conscious motor control of skeletal muscle

primary motor cortex

56

primary motor cortex is blank to central sulcus in the frontal lobe

anterior

57

speech, eye movements, and learned motor skills are driven by this cerebral region

primary motor cortex

58

primary motor cortex is in the blank lobe

frontal

59

this cerebral region is posterior to central sulcus and is in the parietal lobe

primary sensory cortex

60

primary sensory cortex deals with somatic blank information of touch, pain, pressure

sensory

61

this cerebral allows you to monitor the environment consciously

primary sensory cortex
