Perineurium

A

surrounds fasicle

24
Q

Endoneurium

A

surrounds axon and myelin sheath

25
Q

Function of the brain

A

Controls heart rate, respiration, and blood pressure, maintains homeostasis, and controls high level functions

26
Q

Four parts of the brain

A

Cerebrum,diencephalon, cerebellum, and brainstem

27
Q

What is found in the diencephalon

A

3rd ventricle- trains csf

28
Q

Where is the Dienecephalon

A

in the middle of the brain, surrounded by cerebral hemispheres

29
Q

Functions of the Hypothalamus

A

controls ANS, regulates body temp, regulates hunger/thirst, sleep/wake cycles, controls endocrine system, emotional responses, and formation of memory

30
Q

Functions of Thalamus

A

filters somatosensory, visual, and auditory info

31
Q

Functions of the Epithalamus

A

forms roof of 3rd ventricle and holds pineal gland

32
Q

Gyri

A

ridges of brain tissue that help increase surface area

33
Q

Sulci

A

grooves between gyri

34
Q

Functions of the cerebrum

A

intelligence, complex thinking,

35
Q

Function and location of the Primary Motor Cortex

A

F- control voluntary skeletal muscle activity
L- precentral gyrus

36
Q

Function and location of the Primary Somatosensory Cortex

A

F- recieves info from somatic senses and enables concious awareness of senses
L- post central gyrus

37
Q

Function and location of the Auditory Cortex

A

F- recieves and process auditory info from inner ear
L- Temporal lobe

38
Q

Function and location of Visual Cortex

A

F- recieves visual info from retina
L- posterior/medial occipital lobe

39
Q

White matter of the Cerebrum

A

corpus callosum

40
Q

what connects left and right hemispheres

A

corpus callosum

41
Q

Cerebral Nuclei function

A

start, stop, and regulate the intensity of voluntary movements

42
Q

names of cerebral nuclei

A

caudate nucleus, putamen, amygdala, globus pallidus

43
Q

functions of the Brainstem

A

connects cerebrum and spinal cord, start of cranial nerves for innervation of the face and head, autonomic and reflex centers needed for survival

44
Q

Three parts of the Brainstem

A

midbrain
pons
medulla oblongata

45
Q

cerebellum function

A

fine tunes body movements, coordinates body movements, maintain posture and equilibrium

46
Q

limbic system

A

involved with emotion and motivation, and creating, storing, and retrieving memories

47
Q

structures of the limbic system

A

cingulate gyrus- emotional response
hippocampus- stores memory
amygdala- processes fear

48
Q

layers of meninges

A

dura mater-
arachnoid mater-
pia mater-

49
