Study Notes
Cranial Nerves and Associated Structures
- The oculomotor nerve (CN III) innervates the superior oblique, lateral rectus, inferior rectus, and orbicularis oculi muscles, as well as the procerus muscle.
- The ophthalmic artery, a branch of the external carotid artery, enters the orbit through the superior orbital fissure and supplies the lacrimal gland. It also passes by the inferior orbital fissure.
- The inferior ophthalmic vein exits the orbit via the inferior orbital fissure.
- The levator palpebrae muscle is innervated by the oculomotor nerve (CN III).
Cranial nerves and the skull
- The abducens nerve exits the skull through the superior orbital fissure.
- The ophthalmic artery is a branch of the internal carotid artery.
- The posterior ethmoidal artery is a branch of the ophthalmic artery.
- The piriform recess of the pharynx contains internal branch of the superior laryngeal nerve, located in the nasopharynx.
- The lymphoid Waldeyer's ring does not include parotid lymph nodes.
Muscles of the Pharynx and Tongue
- The salpingopharyngeus muscle is a levator of the pharynx.
- The glossopharyngeal nerve innervates the parotid gland, via parasympathetic fibers.
- The vagus nerve exits the skull through the lateral part of the jugular foramen.
- The hypoglossal nerve innervates all the muscles of the tongue except the palatoglossus muscle and travels through the lateral part of the jugular foramen.
Facial Nerve and Associated Structures
- The infraorbital nerve passes through the inferior orbital fissure.
- The pterygopalatine ganglion lies laterally to the optic nerve and receives parasympathetic fibers from the greater petrosal nerve. It receives sympathetic fibers from the external carotid artery plexus and a sensory branch from the mandibular nerve.
- The correct secretory pathway for the lacrimal gland is superior salivatory nucleus - greater petrosal nerve - pterygopalatine ganglion - zygomatic nerve - lacrimal nerve.
- The mandibular nerve has branches including the lingual nerve.
Teeth and Tongue
- The incisors have two roots in the maxilla; premolars have three roots in the maxilla; and molars in the mandible have three roots. The third molar is frequently absent in the deciduous dentition.
- The vallate papillae form a V-shaped row in front of the sulcus terminalis of the tongue.
- The mylohyoid muscle does not belong to the muscles of the tongue
- The orbicularis oris muscle is not a muscle of mastication.
Eye Structures
- The posterior chamber of the eye is part of the fibrous coat.
- The iris is part of the vascular coat.
- The macula lutea is the point of best vision.
Nasal and Ear Structures
- Structures that drain into the middle nasal meatus include the nasolacrimal duct and the maxillary sinuses; frontal, maxillary, and anterior ethmoidal sinuses.
- The facial nerve does not include a nerve for the stapedius muscle, nor does it include the chordae tympani; the chordae tympani are a branch of the facial nerve
- The auditory tube connects the tympanic cavity to the nasopharynx.
Internal Ear Anatomy
- The internal ear contains the incus, concha, sacculus, tragus, stapes, and other ossicles.
