1

What is the primary function of CSF

cushion the brain and protect brain tissue from injury

2

Cerebrum

-largest portion of brain
-cerebral cortex
-responsible for all conscious behavior, enables individual to perceive, remember, communicate, and initiate voluntary movements
-frontal, parietal, occipital, and temporal loves

3

Frontal Lobe of cerebrum

-controls voluntary skeletal movement, speech, emotions, and intellectual activity
-prefrontral cortex controls intellect, complex learning abilities, judgement, reasoning, concern for others, abstract thoughts
-located at front of head
-Alcohol affects area of brain and takes away 'filter' and morals

4

Parietal Lobe of Cerebrum

-responsible for conscious awareness of sensation, somatosensory stimuli including temperature, pain, shapes, and 2 point discrimination, touch, pressure, vibration, sharp vs dull
-located in middle of head between frontal and occipital lobes
-Proprioception (do you know where your body parts are right now)

5

Occipital lobe of Cerebrum

-located at back of skull
-visual cortex recieves stimuli from retina and interprets visual stimuli in relation to past expierences

6

Temporal Lobe of Cerebrum

-Located by each ear
-responsible for interpreting auditory stimuli
-olfactory cortex is in this love and transmits impulses r/t smell
-Superior temporal gyrus
-Wernikes Area: reception of speech
-CN8 (acoustic nerve) hears for you and superior temporal gyrus interprets sound

7

Diencephalon

-contains thalamus, hypothalamus, and epithalamus

8

Hypothalamus of Diencephalon

-autonomic control center, influences bp, pulse, force of heart contraction, digestive motility, respirations, pain perception, pleasure and fear
-temperature,food intake, water balance and sleep cycles

9

Epithalamus of Diencephalon

-helps control moods andsleep cycles
-choroid plexus where CSF is formed

10

Cerebellum

-located below cerebrum, behind brainstem
-skeletal muscle coordination and smooth movements
-maintains equilibrium and muscle tone

11

Brainstem

-contains midbrain, pons, and medulla oblongata
-autonomic control center, influences BP by vasocontricton, respiratory rate, depth, vomitting, hicupping, swallowing, coughing and sneezing
-cardiorespiratory center

12

_________ is key to neuro

Symetry

13

Right precentral gyrus of Frontal Lobe controls:

Left precentral gyrus of Frontal Lobe controls:

Left Side

Right Side

14

Upper Motor Neurons (UMN)

-neurons located in precentral gyrus
-contralateral control

15

Wernicke's Aphasia

-Talk normal grammar, rate and intonation but cannot properly express self using language
-usually unaware of how they are speaking and not realize it doesn't make sense.
-Caused by injury to that area of brain on Left side

16

Jargon Aphasia

-incomprehensible, make sense to the individual.
-Has problems selecting right words, may use similar work with similar sound or just a sound to replace words

17

Auditory Agnosia

-inability to recognize or differentiate between sounds. It -neurological inability of the brain to interpret sound correctly
-Car motor starting, patient may describe it as lion roaring. Unable to make the connection that its a car engine.
-caused by damage to auditory cortex in temporal lobe

18

Cranial Nerve 0

-Nervus Terminalis
-connects to hypothalamic region of sexual function
-pheromones

19

Cranial Nerve 1

-Olfactory
-sense of smell located in temporal lobe

20

Cranial Nerve 2

-Optic
-Vision

21

Cranial Nerve 3

-Oculomotor
-Pupillary reflex
-muslce movement of eye

22

Cranial Nerve 4

-Trochlear
-eye muscle movement

23

Craninal Nerve 5

-Tigeminal
-3 branches: ophthalmic branch, maxillary branch and mandibular branch

24

Cranial nerve 6

-Abducens
-mucles movement of eye

25

Cranial Nerve 7

-Facial
-taste
-facial movement such as smiling, frowning
-tear and saliva production

26

Cranial nerve 8

-Vestibulocochlear
-balance and equilibrium
-hearing

27

Cranial Nerve 9

-Glossopharyngeal
-gag and swolloing reflex
-taste from back of tongue

28

Cranial Nerve 10

-Vagus
-muscles for throat, mouth, swolloing and talking

29

Cranial Nerve 11

-Accessory
-movement of sternocleiodmastoid and trapezius muscles
-movement of soft palate and pharynx

30

Cranial Nerve 12

-hypoglossal
-movement of tongue for swallowing and movement of food
