Q

Mental foramen vs mandibular foramen

A

The mental foramen is on the anterior mandible and allows for the inferior alveolar vessels and nerve to exit renamed “mental ____” The mandibular foramen is on the inside of the angle of the rammus and is where the inferior alveolar nerve and vessels enter the mandible

Q

Part of the brain that maintains autonomic fxn such as blood pressure, heart rate, breathing, vomiting…

A

Medulla oblongata

21
Q

Internal Carotid artery branches- OPAM

A

Ophthalmic Posterior communicating Anterior cerebral Middle cerebral

22
Q

Where does the carotid bifurcate into ICA and ECA?

A

Superior border of thyroid cartilage

23
Q

Contents of cavernous sinus

A

3, 4, 6, V1, V2

Same as superior orbital fissure+ Ro2ndum

V3 and 7 do not go through

ICA and 6 travel through middle

24
Q

Layers of scalp

A

First 3 fused

Skin

CT- vascular

Aponeurosis Epicranialis

Loose areolar Tissue

Paricranium

25
Q

Which cranial nerve crosses over?

A

Trochlear-contralateral innervation

all others ipsi

26
Q

Whne you gag CN_ controls the sensory and CN_ controls the motor

A

Senosry-9

Motor-10

27
Q

Path of bright light being seen then constricting pupils

A

Light seen with CN 2 optic nerve.

Nerve fibers go to Pretectal where they synapse and tell Edenger Westfall to constrict.

Fibers from E.W. go to the ciliary ganglion which then synapse with the eye (miosis/accomidation)

28
Q

What muscle supplies intorsion of the eye?

A

Superior oblique-trochlear CN4

29
Q

TMJ is innervated by which nerve

A

auriculotemporal of mandibular V3

30
Q

Divisions of V1

A

NFL

Nasocilliary

Frontal-Sup orbit, trochlear

Lacrimal

31
Q

Auriculotemporal N, Lingual, and Inferior alveolar N all are from

A

V3

32
Q

Upper vs lower motor lesion/problem on CN7

A

Upper lesion(supranuclear) is a stroke which causes ipilateral paralysis of lower face

Lower lesion(stylomastoid foramen) will cause ipsilateral paralysis of upper and lower face(worse)

33
Q

A lesion at the petrotympanic fissure would sever what and cause what

A

Sever sensory of chorda tympani and cause taste loss (aguesia)

34
Q

only motor action of CN9

A

stylopharyngeus mm

35
Q

This nerve loops areound the subclavian on the right side and the aorta on the left

A

Recurrent laryngeal nerve of CNX

36
Q

CNX inervates all mm of the pharynx and soft palate except…

A

stylopharyngeus(CN9) and Tensor Veli Palatini(V3)

37
Q

The hypoglossal nerve inervates all mm of the tongue except…

A

palatoglossus(vagus)

38
Q

Thoracolumbar vs craniosacral

A

Thoracolumbar is the sympathetic outflow of CNS

Craniosacral is parasympathetic outflow of CNS

39
Q

Lesion at the pterygopalatine foramen would sever what and cause what

A

sever CN7 greater petrosal and prevent lacrimal/nasal secretions

40
Q

Nerve that travels between the otic ganglion and inferior salvitory nucleus

A

lesser petrosal of CN9

after otic, hitch hikes on auriculotemporal of V3 and innervates parotid

41
Q

The atlantoa-occipital joint allows for what motion

A

yes

42
Q

tlanta axial joint allows for what motion

A

no

43
Q

Bones on Roof of orbit

Bones of Medial wall

Lateral

Floor

A

Roof- Front-Less(er wing of sphenoid)

Medial: SMEL: Sphenoid, maxillary, ethmoid, lacrimal

Lateral- Great-Z (greater wing and zygomatic)

My Pal gets his Zzss on the Floor (Max, Pal, zygo)

44
Q

All superior mm (of eye)…

All obliques…

All inferiors…

A

Intort

Superior rectus & Superior oblique

All obliques abduct

All inferior extort

45
Q

The semi-circular canals detect _______ acceleration while the

vestibule detects _______

A

Semi-circular-angular acceleration

vestibule-linear acceleration

46
Q

All superior mm (of eye)…

All obliques…

All inferiors…

A

Intort

Superior rectus & Superior oblique

All obliques abduct

All inferior extort

47
Q

Cranial nerve effects the malleus

Stapes?

A

Malleus- tensor tympani- CN5 V3

Stapes-stapedius CN7

48
Q

Branches of the subclavian artery

A

VIT CD

Vertebral

Internal thoracic

Thyrocervical

Costocervical

Dorsal scapular artery
