CN?
Fossa?
Cell bodies?

A

CN:2 Optic
Fossa: Optic Canal
Horizontal cells receive impulse with synapse w/ Retinal Ganglion cells which converge to form optic nerve

79
Q

What is a cranial meninge?

A

coverings of the brain that are immediately internal to the cranium, create fluid filled cavity aka subarachnoid space.

80

A 
general sensation (pain, temp touch) to ant. 2/3 of tongue
V3- mandibular
81
Q

Layers in cranium below the skull bone

A
  • Dura mater
    • periosteal layer
    • meningeal layer
  • Arachnoid mater
    • subarachnoid space
  • Pia mater
  • brain
82
Q

Lesion along R optic nerve will lead to what type of blindness and visual field?

A

Complete loss of R eye aka blindness of ipsilateral eye aka monocular vision loss

83
Q

CN 10 Motor muscles

A

Palatoglossus
Palatopharyngeus
Sup. Middle. Infer. constrictor
circothyroid

84
Q

What vessel is deep to platysma?

A

external jugular vein

85
Q

The smooth muscles near the insertion on the tarsal plate are innervated by?

Clinical significance?

A

innervated by the sympathetic nervous system!!
in a state of fight or flight the eyes are open wider. with Horner’s syndrome (loss of sympathetic innervation to the face) the patient presents with ptosis as one symptom (drooped eyelid.)

86
Q

Sympathetic innervation to cranium and face via ?
At what vertebra is this located?
Travels along?

A
  • sympathetic chain ganglia
  • superior cervical ganglia @ C1 behind carotid artery
  • Carotid artery
87
Q

Nerves w/i cavernous sinus

A

-3, 4, 6, V1, V2

NOT V3!!!!!

88
Q

Ciliary ganglia can be found on what nerve?

A

Nasociliary N (V1)

89
Q

Lateral venous lucunae

A

how the superior cerebral veins communicate with superior sagittal sinus

these are slit like openings on the lateral aspects of the cerebral veins… aka lateral venous (gap) lacunae

90
Q

Motor Innervation of CN 7 that are not the main 5 terminal branches

A
  • stylohyoid
  • post. belly of digastric
  • stapedius
  • Auricularis muscles (ant. sup. post) and occipitofrontalis
91
Q

Parasympathetic and sympathitics to eye

which CN?

A

parasym: constrict pupils
symp: dilate pupils
CN 3- oculormotor

92
Q

Fibers that feed anterior 2/3 of tongue travel in what nerve? Where are these cell bodies located?

A

Chorda Tympani

ganiculate ganglion

93
Q

medical names for upper and lower eyelids?

A

superior and inferior palpebrae

94
Q

clinical significance of emissary veins?

A

connects superficial veins with diploic veins to dural venous sinuses– these veins are VALVELESS so infections of scalp can gain access to cranial cavity.

This is why scalp wounds are taken so seriously at hospital.

95
Q

Every sympathetic axon in the head is pre or post ganglionic?

A

POSTGANGLIONIC. NO EXCEPTIONS.

96
Q

Innervation of SCM?

A 
#11: motor
C2/C3--pain and proprecooception
97
Q

Main reflections of Dura mater?

A
  • falx cerebri (longitudinal cerebral fissure)
  • think, 2 halfs of brain do not connect other than the corpus cavernousum soooo the dura will go down these halfs and create a reflection*
  • tentorium cerebelli (tent over the cerebellum
  • Falx cerebelli (longitudinal that runs between cerebellums** think falx cerebri but for cerebellums**
  • diaphragma sellae: cicular extension that forms a roof over the hypophysial fossa (aka where pituitary is) this is what allows the cavernous sinus to communicate with one another
98
Q

Sympathetic path to Partoid Gland?

What do these fibers do there?

Size of fibers (aka long or short pre/post gang)

A

Spinal nerves-> SCG-> ride external carotid plexus to superficial temporal art & Maxillary Art -> partoid gland

decrease/inhibit sections

short preganglionic, long postganglionic

99
Q

Branches of Ptyergoid Division of Maxillary Art (in order w/ orientation)

A 
S- DTp: Deep temporal post 
I- PTm: Medial Ptyergoid 
S-PTl: Lateral Ptyergoid
I: MA: Massesteric 
S: DTa: Deep temporal ant
I: BA: Buccal Art
100
Q

Where are cell bodies of CN 7 that are responsible for sensory information located?

A

Both- Geniculate ganglion

  • Special sensory: taste from ant. 2/3rd of tongue and soft palate
  • Somatic Sensory: skin of external acoustic meatus
101
Q

Innervation of geniohyoid

A

C1- cervical plexus

102
Q

the ptergoidpalatine artery goes through what to get to the sphenopalatine fossa?

A

the pterygoid maxillary fissure –> pterygoid palatine fossa –> sphenopalatine fossa

103
Q

V2 exits cranium through what fossa?
Ganglia?
Function?

A
