Rap3 Lesson 10.6 Anatomy & Radiography Of Salivary Glands

Front 1

The space between the teeth and the cheeks

Back 1

Oral Vestibule

Front 2

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.

Back 2

Oral cavity

Front 3

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

Back 3

Frenulum

Front 4

a. substance secreted by mucuos membranes.
b. contains an organic compound
(1) Mucopolysaccharide
(2) main constituent of Mucus

Back 4

Mucin

Front 5

saccular dilation protuding from the wall of a tubular organ.

Back 5

Diverticulum

Front 6

abnormal narrowing of a tubular structure

Back 6

Stricture

Front 7

List the pair of salivary glands located in the mouth from largest to smallest.

Back 7

1. parotid Gland (largest)

2. Submandibular or Submaxillary Gland

3. Sublingual gland (Smallest)

Front 8

List the 2 types of secretory cells and the consistency of the fluid they secrete.

Back 8

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

Front 9

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 in AMYLASE

Back 9

Parotid Gland

Front 10

Runs anteriorly and medially to open into the oral vestibule oppoiste the second upper molar.

Also called the Parotid duct

Back 10

Stenson's Duct

Front 11

-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 parotid glands.
-Also known as the submandibular gland

Back 11

Submaxillary Gland

Front 12

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

Back 12

Wharton's Duct

Front 13

-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 primarily the mucuos type
-smallest of the salivary glands

Back 13

Sublingual gland

Front 14

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.

Back 14

Ducts of Ravinus

Front 15

An occasional anterior sublingual duct that open with or into the submaxillary duct.

Back 15

Duct of Bartholin
