Study Notes
Cranial Nerves and Vessels
- The oculomotor nerve supplies the superior oblique muscle, lateral rectus muscle, inferior rectus muscle, orbicularis oculi muscle, and procerus muscles.
- The ophthalmic artery branches from the external carotid artery. It enters the orbit through the superior orbital fissure and supplies the lacrimal gland. The artery also passes through the inferior orbital fissure.
- The inferior ophthalmic vein leaves the orbit via the inferior orbital fissure.
- The levator palpebrae muscle is innervated by the oculomotor nerve (CN III).
Additional Information
- The abducens nerve exits the skull through the superior orbital fissure.
- The ophthalmic artery has branches, including the posterior ethmoidal artery, angular artery, infraorbital artery, and the carotico-tympanic artery. A superior alveolar artery is also a branch of the ophthalmic artery. The posterior ethmoidal artery is a branch of ophthalmic artery.
- The piriform recess of the pharynx contains the internal branch of the superior laryngeal nerve, which is located in the nasopharynx. This region also contains a fold of the glossopharyngeal nerve.
- The lymphoid Waldeyer's ring does not include the parotid lymph nodes.
- Salpingopharyngeus muscle is a levator of the pharynx.
- The glossopharyngeal nerve innervates the parotid gland via parasympathetic fibers. It does not innervate the parotid gland via sympathetic fibers.
- The submandibular gland and lacrimal gland receive parasympathetic innervation.
- The vagus nerve exits the skull through the lateral part of the jugular foramen.
- The hypoglossal nerve innervates almost all tongue muscles except the palatoglossus muscle. It emerges through the lateral aspect of the jugular foramen.
- The infraorbital nerve passes through the inferior orbital fissure. It supplies the superior lip.
- The pterygopalatine ganglion lies on the lateral side of the optic nerve. It receives parasympathetic fibers from the greater petrosal nerve and sympathetic fibers from the external carotid artery plexus. It also receives a sensory branch from the mandibular nerve.
- The lacrimal gland is innervated by the greater petrosal nerve which connects with the pterygopalatine ganglion.
- The lingual nerve is a branch of the mandibular nerve.
- Incisors have two roots in the maxilla. Premolars and molars generally have three roots in the maxilla.
- The filiform, fungiform, foliate, and vallate papillae are on the tongue. Vallate papillae form a V-shaped row in front of the terminal sulcus.
- The muscles that do not belong to the tongue include the mylohyoid muscles. The mylohyoid line is on the mandible.
- Orbicularis oris is not a muscle involved in mastication, but rather facial expression. Other mastication muscles include masseter, medial and lateral pterygoid muscles, and temporalis.
- The posterior chamber of the eye is a part of the vascular coat.
- The iris is part of the vascular coat.
- The macula lutea is the point of best vision in the eye and is part of the retina.
- The nasal cavity is not supplied by the superior labial, dorsal nasal, anterior ethmoidal, or sphenopalatine arteries.
- The nasolacrimal duct drains into the middle nasal meatus, along with the maxillary sinus, frontal sinus and anterior ethmodial sinus.
- The facial nerve does not contain the nerve for the stapedius muscle as a branch.. It is supplied by the stapedial nerve.
- The facial nerve's motor nucleus is in the pons, not the midbrain.
- The corrugator supercilii muscle is involved in eyebrow wrinkles.
- The muscles of facial expression are innervated by the facial nerve (CN VII), not the branches of the carotid arteries.
- The auditory tube connects the tympanic cavity with the nasopharynx.
- The internal ear contains the incus, concha, sacculus, and stapes.
