Cranial Nerves Flashcards
Nuclei and function of CN III
Oculomotor- somatomotor
WE- GVM (parasympathetic)
Branches and innervation of III
Superior branch- levator palpabrae, superior rectus
Inferior branch- inferior rectus, inferior oblique, medial rectus
Nuclei and function of CN V
Principle sensory- GSS (epicritic)
Spinal- GSS (protopathic)
Mesensephalic- GSS (proprioceptive)
Motor- BM (brachiomotor)
Skull exit of CN V
V1- superior orbital fissure
V2- foramen rotundum
V3- foramen ovale
V1 branches
- Lacrimal
- Frontal (supra trochlear, supraorbital)
- Nasociliary (communicating, long ciliary, post ethmoidal, ant ethmoidal, infratrochlear)
Long ciliary nerve innervates
Dilator papillae muscle
V2 main branches
- Pterygopalatine
- Zygomatic
- Infraorbital
V2, pterygopalatine branches
- nasal branches (post sup lateral, nasopalatine, post sup medial)
- greater palatine (post inf nasal)
- lesser palatine
- pharyngeal
V2, zygomatic branches
- zygomaticotemporal
- zygomaticofascial
V2, infraorbital branches
- ant sup alveolar
- mid sup alveolar
- post sup alveolar
V3 main branches
- Main trunk
- Ant devision
- Post division
V3, main trunk branches
(Main Trunk= 2xM, 2xT)
- meningeal
- medial pterygoid
- tensor tympani
- tensor vali palatini
V3, ant division branches
- masseteric
- deep temporal
- lateral pterygoid
- buccal
V3, post division branches
- auriculotemporal
- lingual
- inf alveolar (mylohyoid, inf dental plexus, mental)
CN VII nuclei and function
- facial nerve (BM)
- sup. Salivary (GVM)
- solitary tract (taste!)
- Spinal trigeminal (GSS)
CN VII main branches
- Intra-cranial
2. Extra cranial
VII, Intra-cranial branches
(In the house there are Great People= greater petrosal. They eat food= chorda tympani. They sense aura= sensory auricular. And they talk very loud so your stapedial works hard)
- greater petrosal
- sensory auricular
- chorda tympani
- stapedial
VII, Extra-cranial branches
- post auricular
- post belly digastric and stylohyiod
- partid plexus
VII, Intra-cranial branches Of the parotid plexus
- temporal
- zygomatic
- buccal
- marginal mandibular
- cervical
Which nerve innervates the lacrimal glands, nasal glands and soft/hard palate glands?
CN VII ->
Intra-cranial branch ->
Greater petrosal nerve
CN IX nuclei and function
- Ambigus (BM)
- Inf. Salivery (GVM)
- Solitary Truct (SVS, taste!)
- Lateral Ala Cinerea (GVS)
- Spinal Trigeminal (GSS)
CN IX main branches
- Tympanic nerve
- Communicating branch to auricular branch of vagus
- Carotid branch
- Pharyngeal plexus
CN IX, pharyngeal plexus branches
(Pam, Tami, Lili, Moran יש להן שם דל בנות שחופרות ביחד וגם גלוסופרינג׳אל זה שם ממש ארוך וחופר)
- pharyngeal
- tonsilar
- lingual
- motor
CN XI nuclei and function
- Ambigus (BM)
- Spinal Accessory (SM)
