-
innervation of the scalp
- V1(ophthalmic)--> supratrochlear and supraorbital
- V2(maxillary)--> zygomaticotemporal
- V3(mandibular)--> auriculotemporal (innervates the parotid gland)
-
cervical enlargement
- same as brachial plexus- C5-T1
-
lumbar enlargement
same as lumbar plexus- L1-S3
-
Innervation of the face
- -CN V
- - V1 triangle to the tip of the nose
- -V2- triangel to the upper lip
- -V3 triangle to the chin
-
where to perform and emergency tracheotomy
- - technically it is a cricothyroidotomy
- -cricothyroid membrane- the membrane between the thyroid and cricoid cartilage.
- - palpate for the adams apple, below that you should be able to palpate the cricoid cartilage. In between the two the is a small indentation, this is where the incision should be made
-
most common site of pharyngeal diverticula
- Killians Dehiscence
- - b/t thyropharyngeus and cricopharyngeus (inferior constrictor)
-
Br 4
- - primary motor area
- - precentral gyrus
- - lesion- contralateral flaccid/spastic paralysis
-
Br 6
- - premotor area
- - lesion- hypokinesia
-
Br 8
- - cortical center for eye movements
- - normally controls contraleteral congugate gaze (R side cortex moves eyes to the left
- - lesion- "right way eyes"- eyes look toward lesion (R lesion-> eye gaze right)
-
Br 3,1,2
- - primary somatosensory area
- - postcentral gyrus
- - VPL and VPM p/w terminate here
- - lesion- contralateral sensory deficits
-
Br 41
- - primary auditory cortex
- - superior temporal gyrus
-
Br 17
- - primary visual cortex
- - around calcarine fissure (cuneate and lingual gyri)
- - optic radiation ends here
-
prefrontal lobe
- - higher cortical function
- - drive, motivation, emotion, judgement, personality etc
- -lesion- variable- personality change, intellectual performance
- -L- more typical depression
- -R- manic behavior, impulsivity, agression
-
Br 44 and 45
- - Brocas motor speech area
- - L inferior frontal gyrus (pars triangularis and pars opercularis)
- - lesion- Broca apahsia- comprehension intact, broc-uh-uh-uhs
-
Br 22, 39, 40
- - Sensory speech center
- -L superior termporal, angular and supramargianl gyri
- - connected to Brocas area via arcuate fascicle- lesion- Word salad
-
kisselbachs area
- Anastomosis of arteries of nose in anterior of nose
- - anterior and posterior ethmoidal arteries (opthalmic a)
- - sphenopalatine artery (maxillary a)
- - greater palatine
- - superior labial (facial)
- - descending palatine (maxillary a)
