What is the Origin of Salivary Gland?

The term is anatomical, derived from the Latin saliva (spit) and glandula (a small acorn, referring to the organ's shape). The use of saliva for hormone testing is a modern clinical application that capitalizes on the passive diffusion of lipophilic steroid hormones.

What is the Mechanism of Salivary Gland?

Steroid hormones, being lipophilic (fat-soluble), readily diffuse from the blood, through the cell membranes of the salivary gland, and into the saliva. Crucially, only the unbound, biologically active fraction of the hormone is able to pass this barrier. This contrasts with serum testing, which primarily measures the total hormone, including the protein-bound, inactive fraction. Therefore, salivary hormone testing offers a precise measure of the fraction of cortisol, DHEA, and sex steroids that is actually available to target tissues.

Salivary Gland

Meaning

The salivary gland is an exocrine gland in the oral cavity responsible for producing and secreting saliva, which is vital for digestion, lubrication, and oral health. In the context of hormonal health, the salivary glands are clinically significant because they provide a non-invasive medium for measuring the biologically active, free fraction of steroid hormones. The concentration of hormones in saliva reflects the tissue availability, offering a valuable assessment tool in endocrinology.

How Do Exogenous Hormones Influence Salivary Test Results?

Exogenous hormones influence salivary tests by altering the bioavailable hormone levels that diffuse into saliva, a process highly dependent on the administration route.
