Gut & Renal Flashcards
the membrane-lined cavity behind the nose and mouth, connecting them to the esophagus.
pharynx
a conic projection from the back edge of the middle of the soft palate, close off the nasopharynx, and prevent food from entering the nasal cavity.
uvula
located on the left and right sides at the back of the throat, which can often be seen as flesh-colored, pinkish lumps. lymphoid tissue
palatine tonsils
a mass of lymphatic tissue situated posterior to the nasal cavity, in the roof of the nasopharynx.
pharyngeal tonsil
two small mounds of lymphatic tissue located in the lamina propria of the root of the tongue.
lingual tonsil
secretes serous saliva through the parotid duct into the mouth
parotid salivary glands
a pair of major salivary glands located beneath the lower jaws, superior to the digastric muscles. the secretion produced is a mixture of both serous fluid and mucus, and enters the oral cavity via the submandibular duct
submandibular salivary glands
are the smallest, most diffuse, and the only unencapsulated major salivary glands. anterior and superior to the submandibular gland and inferior and lateral to the tongue, as well as beneath the mucous membrane of the floor of the mouth.
sublingual salivary glands
the small, nipple-like structures on the upper surface of the tongue that give it its characteristic rough texture. four types: circumvallate (or vallate), fungiform, filiform, and foliate.
papillae
a small fold of mucous membrane extending from the floor of the mouth to the midline of the underside of the tongue.
lingual frenulum

cuspids
a tooth situated between the canine and the molar teeth. an adult human normally has eight, two in each jaw on each side. transitional teeth during chewing, or mastication. have properties of both the canines, that lay anterior and molars that lay posterior, and so food can be transferred from the canines to them and finally to the molars for grinding, instead of directly from the canines to the molars.
