Q

function of brain stem

A

reflex center for respiration, blood pressure, HR, coughing, swallowing;

damage to brainstem can lead to immediate cessation of breathing (immobilize head)

16
Q

cerebellum

A

provides smooth and coordinated movement; controls fine movement, balance and position and postural sense

17
Q

cerebrospinal fluid (CSF)

A

clear, colorless fluid produced in the choroid plexus of the ventricles; importance in immune and metabolic functions of the brain

18
Q

sample of CSF is obtained through

A

lumbar puncture or lumbar tap (spinal tap)

19
Q

Brain cannot store ____

A

glucose

so it needs constant supply of glucose and oxygen

20
Q

cerebral circulation

A

brain receives about 15% of cardiac output, neurons/brain does NOT need insulin to absorb glucose unlike our skeletal muscle cells

21
Q

cerebral circulation (anterior brain)

A

arterial blood supplying anterior brain originates from common carotid artery

22
Q

cerebral circulation (posterior brain)

A

posterior circulation of the brain is supplied by vertebral arteries branching from subclavian arteries

23
Q

Blood brain barrier

A

prevents many substances that circulate in the blood from reaching CNS; this can altered by trauma, cerebral edema, or cerebral hypoxemia

24
Q

spinal cord

A

serves as a connection between brain the periphery; protected by vertebral column

25
Q

vertebral column

A

7 cervical vertebrae
12 thoracic vertebrae
5 lumbar vertebrae
sacrum (fused mass of 5 vertebrae)

26
Q

peripheral nervous system

A

cranial nerves, spinal nerves, autonomic nervous system

27
Q

cranial nerves

A

some say money matters but my brother says big brains matter more
(S= sensory, B= both, M= motor)
(ooo to touch and feel a girls vag a H)

28
Q

olfactory

A

sense of smell

29
Q

optic

A

visual acuity

30
Q

oculomotor

A

muscle that moves the eye and lid, pupillary constriction

31
Q

trochlear

A

muscle that moves the eye

32
Q

trigeminal

A

facial sensation; corneal reflex; mastication

33
Q

abducens

A

muscles that moves the eye

34
Q

facial

A

symmetry of facial expression; muscle movement upper/lower face; salivation; taste; tearing; sensation in the ear

35
Q

acoustic

A

hearing and equilibrium

36
Q

glossopharyngeal

A

taste; sensation in pharynx and tongue, pharyngeal muscles, swallowing

37
Q

vagus

A

muscles of the pharynx, larynx, soft palate, sensation of the external ear, thoracic viscera

38
Q

(spinal) accessory

A

sternocleidomastoid and trapezius muscles

39
Q

hypoglossal

A

movement of the tongue
