Temporomandibular dysfunction or TMD for short, is a condition that may lead to excruciating pain in the jaw joint area. Further more, related symptoms such as such as TMJ clicking, painful jaw muscles, facial neuralgia (trigeminal neuralgia), tinnitus, headaches, migraines are a few worth mentioning (D’Urso et al., 2016; Attanasio et al., 2015; Romero-Reyes & Uyanik, 2014; Franco et al., 2010).

Salivary Glands Numerous glands secrete the watery, somewhat viscous fluid known as saliva into the oral cavity. Small salivary glands are widely scattered under the lining of the oral cavity and are named, according to their location, labial, buccal, palatine, and lingual glands. The three chief, large, paired salivary glands are the parotid, submandibular, and sublingual. The parotid gland, the largest of the salivary glands, is roughly shaped as a three-sided wedge, which is fitted in anterior and inferior to the external ear. The triangular superficial surface of the wedge is practically subcutaneous, with one side of the triangle almost as high as the zygomatic arch and the opposing angle at the level of the angle of the mandible. The anteromedial side of the wedge abuts against and overlaps the ramus of the mandible and the related masseter and medial pterygoid muscles. The posteromedial side of the wedge turns toward the external auditory canal, mastoid process, sternocleidomastoid, and digastric (posterior belly) muscles. The parotid (Stensen) duct leaves the anterior border of the gland and passes superficial to the masseter muscle, at the anterior border of which it turns medially to pierce the buccinator muscle and then the mucous membrane of the cheek near the second maxillary molar. The submandibular gland lies in the submandibular triangle but overlaps all three sides of the triangle, extending superficial to the anterior and posterior bellies of the digastric muscle and deep to the mandible, in the submandibular fossa. Most of the gland is inferior to the mylohyoid muscle, but a deep process extends superior to the muscle. The submandibular (Wharton) duct at first runs anteriorly with the deep process and then in close relation to the sublingual gland (first inferior and then medial to it) to reach the sublingual caruncle at the summit of which it opens, next to the lingual frenulum. The sublingual gland, the smallest of the three paired salivary glands, is located deep to the mucous membrane of the floor of the mouth, where it produces the sublingual fold. It lies superior to the mylohyoid muscle in relation with the sublingual fossa on the mandible. In contrast to the parotid and submandibular glands, which have quite definite fibrous capsules, the lobules of the sublingual gland are loosely held together by connective tissue. About 12 sublingual ducts leave the superior aspect of the gland and open individually through the mucous membrane of the sublingual fold. Some of the ducts from the anterior part of the gland may combine and empty into the submandibular duct. This is apparently prone to considerable variation. The nerve supply of the large salivary glands is dis- cussed in a later segment on the innervation of the mouth and pharynx and the autonomic nervous system. Microscopically, the large salivary glands appear as compound tubular-alveolar glands. The secretions of these glands are serous and mucous and mucous with serous demilunes, with different proportions of these in different glands. The parotid gland is almost entirely serous, the submandibular gland is predominantly serous but with some mucous alveoli containing serous demilunes, and the sublingual gland varies to quite an extent in composition in different parts of the gland but, for the most part, is predominantly mucous with serous demilunes. In the parotid and submandibular glands, the alveoli are joined by intercalated ducts with low epithelium to portions of the duct system, which are thought to contribute water and salts to the secretion and, hence, are called secretory ducts. The epithelium of the ducts is at first cuboidal, then columnar, and may finally be stratified cuboidal near the opening of the duct. It should be noted that the appearance of serous demilunes is an artifact of specimen preparation and that during life, the serous-secreting cells of each acinus sit side by side with the mucous-secreting cells.

The inflammatory response occurs with injuries and chronic illnesses. Some foods are known to increase inflammation in the body, and other foods will decrease inflammation and pain.
Connective Tissue Connective tissue is found everywhere in the body. Each epithelium is given two names. First name indicates the number of cell layers present, and the second describes the shape of its cells. There could be; simple epithelia (single cell layer) typically found where absorption and filtration occur, stratified epithelia (two or more cell layers stacked on top of one another) commonly found in high-abrasion areas where protection is important like the skin surface and the lining of the mouth. Epithelial cells have six irregular sides that looks like a honeycomb. There are three common shapes of epithelial cells; squamous cells are flattened and scalelike their nucleus are flattened disc, cuboidal cells are boxlike approximately as tall as they are wide with a nucleus that is spherical, and columnar cells are tall and column shaped their nucleus is elongated from top to bottom and located towards the cell base. Simple Squamous Epithelium Function: allows passage of materials by diffusion and filtration in sites where protection is not important Location: air sacs of lungs. lining of heart, blood vessels, lymphatic vessels Two simple squamous epithelia in the body have special names that reflect their location. Endothelium "inner covering" and the Mesothelium "middle covering." Simple Cuboidal Epithelium Function: secretion and absorption Location: kidney tubules, ducts and secretory portions of small glands, ovary surface Simple Columnar Epithelium Function: absorption, secretion of mucus, enzymes, and other substances Location: nonciliated type lines most of the digestive track (stomach to anal canal), gallbladder, and some regions of the uterus Stratified Squamous Epithelium Function: protects underlying tissue in areas subjected to abrasion Location: epidermis of the skin, lining of the esophagus, mouth, and vagina. Stratified Cuboidal Epithelium Location: quite rare in the body, mostly found in the ducts of some of the larger glands like the sweat and mammary glands with typically two layers of cuboidal cells Stratified Columnar Epithelium Location: rare in the body but small amounts found in the pharynx, the male urethra, and the lining some glandular ducts Pseudostratified Columnar Epithelium Function: secretion, particularly of mucus, propulsion of mucus by ciliary action. Location: nonciliated type in males sperm-carrying ducts and ducts of large glands, lines the trachea, and most of the upper respiratory tract. The cell nuclei lie at different levels above the basement membrane, but only the tallest reach the free surface of the epithelium. Transitional Epithelium Function: stretches readily and permits distension of urinary organ by contained urine. Location: lines the ureters, bladder, and part of the urethra The ability of transitional cells to change their shape or undergo "transitions" allows a greater volume of urine to flow through. Muscle Tissue Muscle tissues are highly cellular, well-vascularized tissues that are responsible for most types of body movement. Skeletal Muscle Function: voluntary movement, locomotion, manipulation of the environment, facial expression, voluntary control. Location: in skeletal muscles attached to bones or occasionally to skin Cardiac Muscle Function: as it contracts, it propels blood into the circulation, involuntary control Location: the walls of the heart Smooth Muscle Function: propels substances or objects (foodstuffs, urine, a baby) along internal passageways, involuntary control Location: mostly in the walls of hollow organs Nervous Tissue Function: transmit electrical signals form sensory receptors and to effectors (muscles and glands) with control their activity Location: brain, spinal cord, and nerves The main component of the nervous system the brain, spinal cord, and nerves which regulates and controls body functions. Containing two major cell types.
