What cells are in the salivary glands?
The salivary gland epithelium is composed of two types of saliva-producing cell types, serous acinar cells and mucous acinar cells.
What are the two main structures of the salivary glands?
Each gland’s major duct (Stensen’s duct) opens in the rear of the mouth cavity near the second upper molar. The second pair, the submaxillary glands, also called submandibular glands, are located along the side of the lower jawbone.
What are the major salivary glands made of?
Salivary glands are made up of secretory acini (acini – means a rounded secretory unit) and ducts. There are two types of secretions – serous and mucous. The acini can either be serous, mucous, or a mixture of serous and mucous. A serous acinus secretes proteins in an isotonic watery fluid.
What are the two types of saliva?
Saliva consists of two fluids, mucous and serous.
- Mucous.
- Serous Fluid.
- Types of salivary gland.
- Structure of salivary glands.
What are the 3 types of salivary glands?
There are three pairs of major salivary glands: the parotid glands, the submandibular glands, and the sublingual glands.
- Parotid Glands. The parotid glands are the largest salivary glands.
- Submandibular Glands. About the size of a walnut, the submandibular glands are located below the jaw.
- Sublingual Glands.
What are the three main pairs of salivary glands?
The three main pairs of salivary glands are the parotid glands, the sublingual glands, and the submandibular glands.
What are the two main cell types found in salivary glands and what are their secretions?
Two basic types of acinar epithelial cells exist: serous cells, which secrete a watery fluid, essentially devoid of mucus. mucous cells, which produce a very mucus-rich secretion.
Where is your main salivary gland?
The major salivary glands, three pairs in total, are found in and around your mouth and throat. The major salivary glands are the parotid, submandibular, and sublingual glands. The parotid glands are located in front and beneath the ear.
What are the 3 salivary glands?
Are there different types of saliva?
parotid glands produce a serous, watery secretion. submaxillary (mandibular) glands produce a mixed serous and mucous secretion. sublingual glands secrete a saliva that is predominantly mucous in character.
Where are the 3 salivary glands located?
There are three pairs of large salivary glands. Parotid glands are found in front of and just below each ear. Submandibular glands are below the jaw. Sublingual glands are under the tongue.
What are the two types of movements within the alimentary canal?
The motor functions of the alimentary canal are of two types–mixing movements and propelling movements. 2. Mixing movements occur when smooth muscles contract rhythmically in small sections of the tube.
What kind of cells are in the salivary glands?
Salivary glands contain three major cell types: acinar cells, ductal cells, and myoepithelial cells. Despite their different locations, each of these glands shares the same fundamental structure, branched ducts that open into the oral cavity and glandular secretory end pieces, called acini, that produce saliva.
What kind of saliva does the sublingual gland secrete?
sublingual glands secrete a saliva that is predominantly mucous in character The basis for different glands secreting saliva of differing composition can be seen by examining salivary glands histologically. Two basic types of acinar epithelial cells exist: serous cells, which secrete a watery fluid,…
Which is part of the parotid glands secrete mucus?
serous cells, which secrete a watery fluid, essentially devoid of mucus mucous cells, which produce a very mucus-rich secretion Acini in the parotid glands are almost exclusively of the serous type, while those in the sublingual glands are predominantly mucus cells.
What kind of secretion does the serous gland produce?
Serous cells produce a watery secretion containing ions, enzymes, and a small amount of mucin. Mucous cells produce mucus. The submandibular and parotid glands contain a large percentage of serous cells. The sublingual glands contain mostly mucous cells.
