Gnathology
Gnathology is the study of the masticatory system, including its physiology Physiology (; ) is the science, scientific study of function (biology), functions and mechanism (biology), mechanisms in a life, living system. As a branches of science, subdiscipline of biology, physiology focuses on how organisms, organ syst ..., functional disturbances, and treatment. Dr Beverly McCollum established the Gnathologic Society in 1926. Chairman of the Board of Directors, David W. McLean DDS represented the So. Cal. Gnathology Society in 1929 in Mexico City, furthering the Society's work. “The study of the relationship of the mandibular border movements and occlusal morphology, and how this relationship affects the anatomy, histology, physiology, pathology, and therapeutics of the oral organ, as well as how this relationship affects the rest of the body, including, but not limited to, the TMJ.” Dr. Jack Hockel, editor of Orthopedic Gnathology by Quintessence, 1983.

Mastication
Chewing or mastication is the process by which food is comminution, crushed and ground by the teeth. It is the first step in the process of digestion, allowing a greater surface area for digestive enzymes to break down the foods. During the mastication process, the food is positioned by the cheek and tongue between the teeth for grinding. The muscles of mastication move the jaws to bring the teeth into intermittent contact, repeatedly occlusion (dentistry), occluding and opening. As chewing continues, the food is made softer and warmer, and the enzymes in saliva begin to break down carbohydrates in the food. After chewing, the food (now called a Bolus (digestion), bolus) is swallowed. It enters the esophagus and via peristalsis continues on to the stomach, where the next step of digestion occurs. Increasing the number of chews per bite stimulates the production of digestive enzymes and peptides and has been shown to increase diet-induced thermogenesis (DIT) by activating the sympa ...

Physiology
Physiology (; ) is the science, scientific study of function (biology), functions and mechanism (biology), mechanisms in a life, living system. As a branches of science, subdiscipline of biology, physiology focuses on how organisms, organ systems, individual organ (biology), organs, cell (biology), cells, and biomolecules carry out chemistry, chemical and physics, physical functions in a living system. According to the classes of organisms, the field can be divided into clinical physiology, medical physiology, Zoology#Physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysics, biophysical and biochemical processes, homeostasis, homeostatic control mechanisms, and cell signaling, communication between cells. ''Physiological state'' is the condition of normal function. In contrast, ''pathology, pathological state'' refers to abnormality (behavior), abnormal conditions, including human diseases. ...

Therapy
A therapy or medical treatment is the attempted remediation of a health problem, usually following a medical diagnosis. Both words, ''treatment'' and ''therapy'', are often abbreviated tx, Tx, or Tx. As a rule, each therapy has indications and contraindications. There are many different types of therapy. Not all therapies are effective. Many therapies can produce unwanted adverse effects. ''Treatment'' and ''therapy'' are often synonymous, especially in the usage of health professionals. However, in the context of mental health, the term ''therapy'' may refer specifically to psychotherapy. Semantic field The words ''care'', ''therapy'', ''treatment'', and ''intervention'' overlap in a semantic field, and thus they can be synonymous depending on context. Moving rightward through that order, the connotative level of holism decreases and the level of specificity (to concrete instances) increases. Thus, in health-care contexts (where its senses are always nonc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
