MindMap Gallery system anatomy cranial nerves
Cranial nerves, one smelling, two seeing, three moving eyes, four gliding, five forks and six abducting, listening in all directions and nine glossary and pharynx, vagus and sublingual nerves, let’s take a look at the sensory cranial nerves, mixed cranial nerves, and motor brain nerves. Neurological knowledge.

cranial nerve
general somatosensory fibers
Skin, muscles, tendons, mouth and nose
Special somatosensory fibers
general visceral sensory fibers
Special visceral sensory fibers
General somatic motor fibers
Sarcomeric evolved extraocular muscles, tongue muscles
Special visceral motor fiber (parasympathetic nerve)
General visceromotor fibers (parasympathetic nerves)
trigeminal ganglion
Ocular nerve (general somatosensory)
frontal nerve
Supraorbital nerve → skin above eye fissure
supratrochlear nerve
lacrimal gland nerve
nasociliary nerve
Maxillary nerve (general somatosensory)
infraorbital nerve
Zygomatic nerve
superior alveolar nerve
pterygopalatine nerve
Mandibular nerve (mixed)
Auriculotemporal nerve: conducts the parasympathetic fibers of the glossopharyngeal nerve into the parotid gland
Lingual nerve: the anterior 2/3 mucosa of the tongue, joined by the chorda tympani of the facial nerve
Inferior alveolar nerve → mandibular teeth, the terminal branch is the mental nerve → skin below the oral cleft
Masticatory muscle nerves: motor, innervating four masticatory muscles
cranial nerve
One smell, two looks, three eye movements Four slides, five forks and six abductions Listening on all sides and swallowing with nine tongues Vagus sublingual whole
sensory cranial nerve
I olfactory nerve
II optic nerve
ⅧVestibulocochlear nerve (conducts balance sense)
mixed cranial nerve
V trigeminal nerve
somatosensory
Head and face skin and mucous membranes
somatic mobility
Masticatory muscles
VII facial nerve
Clinical manifestations of facial nerve injury
branches within facial nerve canal
Chordrum tympani: Course: Facial nerve exits in front of the stylomastoid foramen → tympanum → joins the lingual nerve → taste sensation in the front 2/3 of the tongue
Join the lingual nerve → submandibular ganglion → submandibular gland, sublingual gland
Greater petrosal nerve (parasympathetic nerve) → pterygopalatine ganglion → lacrimal gland
stapedius nerve → stapedius muscle
Extracranial branches
temporal branch
Zygomatic branch
buccal branch
marginal mandibular branch
cervical branch
IX glossopharyngeal nerve
Xvagus nerve
Contains visceromotor components, which are parasympathetic nerves
motor cranial nerve
III oculomotor nerve
oculomotor nucleus
accessory nucleus of oculomotor nerve
Superior branch → superior rectus, levator palpebrae superioris
Inferior branch → inferior rectus, medial rectus, inferior oblique muscle
IV trochlear nerve
VI abducens nerve
XI accessory nerve (manages sternocleidomastoid and trapezius muscles)
XII hypoglossal nerve
