|
|
|
Role of Medial Vestibule Spinal tract =
|

7 Motor (innervates orbital Myo & blinking) |
|
|
|
2ct
1) mechanical trauma of branches of 7th N = 2) bells palsey of Peripheral 7th N |
1a) central leision = decusates on mouth droop-paralysis
1b) peripheral Leision (same side) facial paralysis (Answ) 2) Damage is of CN7 thru styloid mastoid foreman |
|
|
|
Which Nucleus do the fibers for pupilary reflex
|
N2 afferent Sensory
& N3 constriction-bilat Motor nucleus of 3rd N (WESTPHAL/EttINGER nucleus) Parasympathetic N |
|
|
|
Pt has Leision on 1 side of 12th N
where is the tongue to protrued on which side |
Same side (peripheral Leision)
|
|
|
|
Which Nucleus are the fibers for the pupillary reflex
|
Ettinger Westphal
N2 optic afferent Sensory & N3 pretectal nuclei constriction-bilat Motor nucleus of 3rd N (WESTPHAL/EttINGER nucleus) Parasympathetic N |
|
|
|
Cerebellum:
what fibers are the input for purkinge fibers |
Climbing fibers (Indirect)
Mossey (direct) |
Which cells are negative in the cerebellum = granular cells (inhibitory)
|
|
|
what is Dismetria =
What is Dysoli |
Over shoot the target while trying to catch it.
(Dysmetria (English: difficult to measure) refers to a lack of coordination of movement typified by the undershoot or overshoot of intended position with the hand, arm, leg, or eye. It is a type of ataxia. It is sometimes described as an inability to judge distance or scale) What is Dysdiadochokinesia = fast alternative movements have leison in cerebellum and they can not due to the leision |
dys "bad", diadocho "receive", kinesia "movement"),
often abbreviated as DDK, is the medical term for impaired ability to perform rapid, alternating movements |
|
|
What part of cerebellum is damaged in cerebellar leision =
|
Vermis
Vermis damage = action of patient is Ataxic /ataxia |
|
|
|
cerebellar leision you can expect
|
Tremor
Ataxia last S/S: Positive Rhomberg (Proprioception .... medial lemniscus pathway Leison) |
|
|
|
What is the course of the cortical pons cerebellar fibers
|
starts in
cortex to Pons decustaes to medial cerabellar peduncle ends in cerebellum (answ) |
Mid barain
Pons Medulla |
|
|
leision damages
(53 minutes) |
dorsal medial -
dorsal anterior - ...... related to Limbic motor nuclei Emotion long term behavior ventral anterior - ventral lateral.... input motor output is prefrontal & premotor |
medial thalamic nucliei
input is reticular output = prefrontal aurora for arousal attention memory lateral reticular nucliei is NOT associated with reticular formation. |
|
|
2Q
ventral anterior Nucleus what is the input & output |
(motor-input / / / prefrontal
& premotor cortex -output |
|
|
|
medial thalamic nuclieic topic
role is 3 Q |
(assoc-Reticular formation)
-Arousal -attention -Memory Input is: = Output: = |
Input is: reticular system
Output: prefrontal cortex |
|
|
Hypothalamus
leison of lat-hypo thalamus ...what can you expect: |
aphagia (Not Hungry)
|
|
|
|
What is suprachiasmatic Nucleus =
inputs for Darkness which triggers = |
Circadian Rhythm
Seratonin in pineal gland to produce melationin |
|
|
|
Hypothalamus Slide #42
Arcuate Nucleus What is the role = |
-Feeding centers
-release hormones for stimulating anti-pituitary gland to release dopa & stops prolactin What starts prolactin = When Breast feeding it inhibits the Arcuate Nucleus |
Pt has tumor in 3rd ventricle = compresses arcuate nucleus & will stop the hormone & galactarhea
|
|
|
Hypothalamus Slide #29
which nucleus makes you have the sense of fullness (satiety) = |
ventral Medial nucleus of hypothalamus
|
|
|
|
Hypothalamus Slide #10
what can mod the autonomic nervous system |
Hypothalamus
amygdila (part of the Lymbic System) can modualate the ANS. They will send impulses to the solitary nucleus |
|
|
|
Cranial N slide # 47
Pt has px after swallow & cough |
Leison is of 9 CN
|
|
|
|
Cranial N slide # 47

motor componant = nucleus ambiguous
Sensory Componant = |
superior ganglion
|
|
|
7th cranial Nerve
3Q -loss of taste but no Damx of taste receptors = sensory N..Solitary Nucleus CN 7, 9,10 |
