⑴ Mouth (upper group of muscles around the lips, lower group of muscles around the lips, orbicularis oris muscle)

⑵ Nose (nasal muscle, depressor septum muscle, rhizome muscle)

⑶ Orbital (orbicularis oculi, corrugator supercilii)

⑷ Ear (preauricular muscle, supraauricular muscle, postauricular muscle)

common carotid artery

subclavian artery

a. Communicates with the intracranial cavernous sinus b. Some lack venous valves c.Danger triangle

Large sense (eyes, upper and lower jaw) small movements chewing

⑴ Ocular nerve (general somatosensory fibers)

⑵Maxillary nerve (general somatosensory fibers)

(3) Mandibular nerve mixed

⑴ Temporal branch ⑵ Zygomatic branch ⑶ Buccal branch ⑷ Mandibular marginal branch ⑸ Cervical branch

The parotid duct is located in the anterior and lower part of the external auditory canal and the posterior mandibular fossa, opening at the papilla of the parotid duct, facing the buccal mucosa of the crown of the maxillary second molar.

——Opening at the sublingual caruncle ——Opens into the sublingual caruncle and sublingual fold (large tube) (small tube

remember

Divided into two parts by the boundary ditch: Tongue body, tongue base

contoured nipples foliate papillae Filamentous papillae (no taste buds) fungiform papillae

Intrinsic tongue muscles – change the shape of the tongue External tongue muscles – change the position of the tongue

Mainly the lingual artery and its branches The posterior 1/3 of the tongue is joined by the ascending pharyngeal artery

General sensation (pain, warmth, touch, pressure) Trident Anterior 2/3, lingual nerve; posterior 1/3, glossopharyngeal nerve Special sense (taste) The anterior 2/3, facial nerve chorda tympani; the posterior 1/3, glossopharyngeal nerve; the middle part of the posterior 1/3 is conducted by the vagus nerve

Movement: Mostly the hypoglossal nerve, the palatoglossal muscles are innervated by the vagus nerve

Cardia—left side of the 11th thoracic vertebra Pylorus—right side of 1st lumbar vertebra

Subtopic The septal omentum sac of the posterior wall of the stomach is adjacent to the pancreas, left adrenal gland, left kidney, spleen, transverse colon and its mesentery, and these organs together form
