Front Back
  • Stylopharyngeus muscle dives btw the superior and middle constrictor mm and also runs along with the glossopharyngeal nerve and stylohyoid ligament
  • At the top of the superficial face, you can see the superficial temporal artery going high as the terminal br. The next lowest br is the transverse facial a if it is not cut (differentiate this from the maxillary artery)
  • Greater and lesser palatine nn – greater goes forward in nasal cavity and lesser goes backwards
  • Submandibular duct which attaches sublingual gland to the submandibular gland crisscrosses with the lingual nerve
  • From a lateral view, you can see the lingual artery going under the hypoglossal nerve.  Other relation is in reference to the hyoglossus muscle:  the lingual artery goes under the hyoglossus m and the hypoglossal nerve goes over top of the hyoglossus muscle.
  • Pharygeal raphe is the common attachment of the sup, middle, and inf constrictor mm
  • Underthe middle concha is the semilunar hiatus (to the frontal sinus by way of the frontal nasal duct), the ethmoid bulla, and the maxillary sinus
  • The taste bud we can see is the vallate papilla
  • Parotid duct and buccal br of facial nerve go into the buccal fat pad
  • Zygomatic br of facial nerve goes into zygomaticus major m
  • Brs off of the facial artery:  inferior and superior labial aa go below and above the lip.  The angular a is the terminal br up the side of the nose
  • Depressor anguli oris runs on the angle of the mouth downwards
  • Inferior alveolar n and a run together into the mandibular foramen….the mylohyoid nerve branches off before the foramen ot innervate the anterior belly of the digastric m and the mylohyoid muscle
  • Off the maxillary artery:  middle meningeal artery goes up btw the two roots of the auriculotemporal nerve; the deep temporal artery goes to the temporalis muscle
  • From inferior to superior runs the anterior belly of digastric, the mylohyoid, the geniohyoid and genioglossus; differentiate the geniohyoid from the mylohyoid by the fiber direction
  • Ascending pharnyngeal artery goes up btw the bifurcation of the internal and external carotid aa
  • The descending palatine artery runs with the greater and lesser palatine nerves
  • Through the thyrohyoid membrane is the internal layngeal nerve and the superior laryngeal artery
  • Know the bony features of the hyoid bone:  greater horn is lateral and lesser horn is medial; also know the body
  • Superior ane inferior horn of the thyroid cartilage
  • Know the median glossoepiglottic and lateral glossoepiglottic folds that attach epiglottis to the tongue and show the valleculae
  • Looking at the lateral view of the cheek deep to the masseter will be the inferior alveolar (with mylohyoid n coming off), the lingual more anteriorly and the buccal nerve even more anteriorly
  • The chorda tympani is very small and connects facial to the lingual
  • The hypoglossal nerve runs beneath the posterior belly of the digastric muscle and pierces the mylohyoid muscle; lingual a runs with it
  • Submandibular gland is split by mylohyoid muscle
  • Stylohyoid starts more anteriorly than the posterior belly of the digastric but ends more inferiorly – to see this look for the common tendon of the digastric muscle and follow it up
  • In a cross section, superior to the cricoid cartilage is the transverse arytenoid muscle that looks circular in cross section
  • Make sure to orientate yourself when differentiating btw the posterior cricoarytenoid and lateral cricoarytenoid mm
  • External carotid a brs : SALFOPSM (some anatomists like fucking, others prefer S and M):  key:  superior thyroid first br (look for sup laryngeal going to thyrohyoid membrane), ascending pharyngeal goes btw bifurcation upwards, lingual goes with hypoglossal nerve, facial goes to jaw, occipital goes back, posterior auricular goes back behind ear, maxillary, and superficial temporal is terminal br (don’t forget transverse facial too)
  • Palatine tonsil lies in lateral to the tongue; the palatine gland lies in the soft palate
  • ORBIT RELATIONSHIPS:
  • Frontal nerve splits into the supraorbital and supratrochlear (trochear is more medial)
  • Frontal nerve sits on top of the levator palpebrae superioris muscle which sits on top of the superior rectus muscle
  • Trochlear nerve goes into superior oblique and runs on top of it
  • Nasociliary nerve is under superior oblique and gives off anterior ethmoidal nerve, and infratrochlear nerve
  • Lateral rectus is lateral and abducens nerve is under lateral rectus muscle
  • OPTIC NERVE IS DADDY NERVE
  • Lacrimal nerve is on top of the lateral rectus muscle
  • Superior oblique muscle is on top of the medial rectus muscle
  • Inferior rectus is on the bottom of the eye
  • Opthalmic artery is tubular structure lateral to the optic nerve (usually)
  • Ciliary ganglion is more lateral and in the back and has a bunch of nerves coming off of it….(hard to see)
