- The space between the teeth and the cheeks
- Oral Vestibule
-
a. the space between the dental arches
b. the hard and soft palates form the roof
c. Principally the tongue forms the floor, and it communicates with the pharynx. - Oral cavity
-
a. Vertical band or fold of mucous membrane
b. restricts posterior movement of the free anterior part of the tongue.
c. Located on underside of tongue - Frenulum
-
a. substance secreted by mucuos membranes.
b. contains an organic compound
(1) Mucopolysaccharide
(2) main constituent of Mucus - Mucin
- saccular dilation protuding from the wall of a tubular organ.
- Diverticulum
- abnormal narrowing of a tubular structure
- Stricture
- List the pair of salivary glands located in the mouth from largest to smallest.
-
1. parotid Gland (largest)
2. Submandibular or Submaxillary Gland
3. Sublingual gland (Smallest) - List the 2 types of secretory cells and the consistency of the fluid they secrete.
-
1. Serous Cells - Produces a watery fluid that contains a digestive enzyme called amylase
2. Mucous Cells - Secrete a thick liquid called Mucus.
(a) Binds food particles
(b) acts as lubricant during swallowing
*** Both has SYMPATHETIC and PARASYMPATHETIC nerve -
Largest of the major salivary glands.
Each consist of a flattened superficial portion and wedge-shaped deep portion
Located between the skin of the cheek and the masseter muscle
Secretes a clear watery fluid that is rich - Parotid Gland
-
Runs anteriorly and medially to open into the oral vestibule oppoiste the second upper molar.
Also called the Parotid duct - Stenson's Duct
-
-Fairly large
-Irregularly shaped
-Located in the floor of the mouth on the inside surface of the lower jaw.
-Secretory cells of these glands are predominantly serous, with a few mucuos cells.
-Secretes a more viscoud fluid than the - Submaxillary Gland
-
Extends anteriorly and superiorly to open into the mouth ona small papilla at the side of the frenulum of the tongue
also called the submandibular duct or submaxillary duct - Wharton's Duct
-
-Narrow and elongated
-Located in the floor of the mouth beneath the sublingual fold.
-Each is in contact with the mandible laterally and extends posteriorly from the side fo the frenulum of the tongue to the submandibular gland
-cells are - Sublingual gland
-
Also known as sublingual ducts.
Some of these ducts open into the floor of the mouth along the crest of the sublingual fold.
some open into or near the submandibular duct. - Ducts of Ravinus
- An occasional anterior sublingual duct that open with or into the submaxillary duct.
- Duct of Bartholin
