Oculomotor Nerve Modalities: GSM: From: Oculomotor complex. To: 4 of 6 extrinsic muscles of the eye. Levator palpebrae superioris.
Oculomotor Nerve Modalities: GVM: Preganglionics: From: Edinger-Westphal nucleus. To: Ciliary ganglion. Postganglionics: To: Sphincter pupillae.
Trigeminal Nerve Three branches: Ophthalmic. Maxillary. Mandibular. Major sensory nerve to face. (Also supplies tongue, but this is general sensory, not special sensory for taste.) Motor to muscles of mastication: Muscles derived from first pharyngeal arch (mandibular arch).
Trigeminal Nerve Not parasympathetic. Modalities: SVM: From: Masticator nucleus. To: Muscles of mastication. Tensor veli palatini. Tensor tympani. Mylohyoid. Anterior belly of digastric.
Trigeminal Nerve Modalities: GSS: Cell bodies of sensory neurons in trigeminal (semilunar) ganglion. Sensory to: Face and anterior scalp. Conjunctiva and eyeball. Paranasal sinuses. Nasal and oral cavities. Anterior 2/3 of tongue. External surface of ear drum. Dura of middle and anterior cranial fossae.
Facial Nerve Primary motor nerve to muscles of facial expression. Supplies muscles derived from second pharyngeal arch (hyoid arch). Branches: Temporal. Zygomatic. Buccal. Mandibular. Cervical.
Facial Nerve Carries taste from anterior 2/3 of tongue. Carries motor to submandibular and sublingual salivary glands. Carries motor to lacrimal gland and mucous glands in nose.
Facial Nerve Modalities: GVM: Preganglionics: From: Superior salivatory and lacrimal nuclei. To: Submandibular/sublingual ganglia.
Facial Nerve Modalities: GVM: Postganglionics: To: Lacrimal gland. Submandibular gland. Sublingual gland. Mucous glands of mouth and nose.
Facial Nerve Modalities: GSS: Cell bodies of sensory neurons in geniculate ganglion. Supplies sensory to part of external ear.
Facial Nerve Modalities: SVS: Cell bodies of sensory neurons in geniculate ganglion. Carries taste from anterior 2/3 of tongue. Carries taste from hard and soft palates.
Glossopharyngeal Nerve Motor to parotid gland. Carries taste from posterior 1/3 of tongue. Supplies general sensation to posterior 1/3 of tongue. Supplies muscles derived from third pharyngeal arch.
Glossopharyngeal Nerve Modalities: SVM: From: Nucleus ambiguous. To: Stylopharyngeus.
Vagus Nerve Motor to muscles of larynx: Muscles of fourth and fifth pharyngeal arches. Important in swallowing and speaking. Major parasympathetic nerve to thoracic and abdominal organs: Parasympathetic supply distally to left colic (splenic) flexure.
Vagus Nerve Modalities: SVM: From: Nucleus ambiguous. To: Almost all muscles of pharynx and larynx.
Vagus Nerve Modalities: GVS: From: Larynx and pharynx. Thoracic and abdominal viscera. GSS: From external ear and pharynx.
Vagus Nerve Modalities: GVM: Preganglionics: From: Dorsal motor nucleus. To: Myenteric plexus of wall of gut tube.
Vagus Nerve Modalities: GVM: Postganglionics: Smooth muscle of pharynx and larynx. Smooth muscle of most of wall of gut tube.
