bone; alveolar process forms the bone that supports the maxillary and
mandibular teeth.

- alveolar process - -the bone that supports the teeth in both the arches.

- angle of the mandible - -where the ramus meets the body of the mandible
on the outside border.

- anterior alveolar nerve - -one of the two nerves that comes from the
infraorbital nerve before it exits through the infraorbital foramen.

- anterior superior alveolar artery - -supplies blood to the anterior teeth.

- anterior tonsillar pillars - -folds of tissue that extend horizontally from the
uvula to the base of the tongue.

- articular disc - -also known as meniscus, it is dense, fibrous connective
tissue that is thicker at the ends attached to the condyle.

- buccal nerve branch - -nerves that pass through the buccinator muscles to
the cheek where it innervates the buccal mucosa, buccal gingiva, and the
buccal of the mandibular molars.

- buccal mucosa - -The inner surface of the cheeks.

- buccinator - -a muscle of facial expression.

- circumvallate papilla - -The largest papilla, mushroom shaped, are anterior
to the sulcus terminalis in a row of eight to ten.

- common carotid - -artery supplying blood to most of the head and neck,
divided into the internal and external branches.

- condyle - -The posterior projection at the top of the rami

- condyloid process - -The posterior projection at the top of the
rami;condyle.

, - coronoid process - -The anterior projection at the top of the rami.

- deep facial vein - -a tributary of the facial vein which connects the facial
vein to the pterygoid plexus of veins.

- dental arteries - -supplies blood to the roots and periodontal ligaments of
the molars and premolars.

- digastric - -one of the muscles of the floor of the mouth that lifts the hyoid
bone and assists in the opening of the mouth.

- ducts of bartholin - -route to the sublingual caruncles of saliva from the
sublingual glands.

- ethmoid sinuses - -contained within the thin, spongy ethmoid bone.

- external auditory meatus - -opening of the ear.

- external carotid artery - -supplies blood to the face and oral cavity and has
many branches.

- external jugular vein - -vein that drains the superficial veins of the face
and neck into the subclavian vein.

- external oblique ridge - -extending from the mental foramen, follows the
length of the body of the mandible past the last tooth and up to the ramus.

- external pterygoid muscles - -one of the muscles of mastication, opens
jaw by depressing the mandible.

- extrinsic muscle - -assist in the movement and functioning of the tongue,
includes genioglossus, hyoglossus, styloglossus, and palatoglossus.

- facial nerve - -mixed nerve that controls muscles of the scalp and face.
provides sensations over the face and receives taste information from the
tongue.

- facial artery - -contains six branches that supply blood to the pharynx
muscles, soft palate, tonsils, the posterior of the tongue, submandibular
gland, muscles of the face, nasal septum, the nose and eyelids.

- facial vein - -drains the facial structures, beginning near the eye and
descending toward the mandible.
