Summary of Mixed cranial nerves

Summary of Mixed cranial nerves: (V, VII, IX, X)

·         Trigeminal nerve,

·         Facial,

·         Glossopharyngeal,

·         Vagus 

Trigeminal nerve (V)

It has three parts

		Foramen	Function	Nucleus of trigeminal nerve
Ophthalmic nerve	sensory nerve	Superior orbital fissure	Carry sensation from Upper part of face	Motor nucleus of trigeminal nerve Spinal nucleus of trigeminal nerve Main sensory nucleus of trigeminal nerve and  mesencephalic nucleus of trigeminal nerve
Maxillary nerve	sensory nerve	Foramen Rotundum	Carry sensation from Middle part of face
mandibular nerve	Mixed : both sensory and motor	Foramen ovale	Sensory : Lower part of face & general sensation from the ant 2/3 of tongue Motor : muscles of mastication, tensor tympani, tensor veli palatine

 

Facial nerve (VII) Functions (in short):

Sensory function: carry taste sensation from ant 2/3 of tongue

Motor function: motor innervation of muscles of facial expression

Secretomotor function: innervate lacrimal gland through pterygopalatine ganglion 

Glossopharyngeal nerve functions(IX) (in short):

Sensory function: carry taste sensation and general sensation from pos 1/3 of tongue 

Motor function: innervate stylopharyngeus muscle

Secretomotor function: innervations of parotid gland through otic ganglion

Vagus nerve(x) function in short :

Sensory function: carry taste sensation from post most part of tongue, carry sensation from larynx, external ear

Motor innervations: muscles of larynx
