An area of skin that overlies a bony prominence and is subject to pressure injury or ulceration.absorbent pointA cone of paper used in drying or in keeping liquid medicines in a root canal of a tooth.active trigger pointA trigger point that is painful without stimulation. Palpation will reproduce the patient’s symptoms. acupuncture pointAny anatomical location used in acupuncture to relieve symptoms or treat disease.ah-shi pointA tender point on the body; a trigger point.auricular pointThe center of the external orifice of the auditory canal.Boas point See: Boas pointboiling pointThe temperature at which a liquid boils. The boiling point of a liquid varies according to the chemicals present in it. Under ordinary conditions water boils at 212°F (100°C) at sea level. To kill most vegetative forms of microorganisms, water should be boiled for 30 min. Broca point See: Broca, Pierre-PaulCapuron point See: Capuron pointcardinal point1. Any of six points determining the direction of light rays emerging from and entering the eye. See: nodal point; principal point2. Capuron point.point of careAny location where patient care is provided, e.g., the bedside, radiology suite, emergency room, clinic, or ambulance.cold rigor pointThe temperature at which cell activity ceases.contact pointThe point on a tooth that touches an opposed tooth.convergence point1.

See: craniometry for illuscritical point of gasesThe temperature at or above which a gas is no longer liquefied by pressure.critical point of liquidsThe temperature above which no pressure may retain a substance in a liquid form.cut pointIn an analysis of data, a specified value used to sort continuous variables into discrete categories. It may be set according to its usefulness in predicting abnormal clinical events or arbitrarily. Blood pressure measurements, for example, are continuous variables: in general, the higher one's pressure, the greater one's risk of congestive heart failure, kidney disease, myocardial infarction, or stroke. The analysis of blood pressure measurements has shown that the risk for these events climbs sharply as systolic blood pressures rise above 139 mm Hg. Therefore hypertension is defined by the cut point of 140 mm Hg, even though lower pressures may be harmful for some patients and higher pressures may be relatively well tolerated by a small number of other patients. deaf point of the earAny of several points or areas close to the external auditory meatus where a vibrating tuning fork is not heard.disparate pointsPoints on the retinas that are unequally paired.end point, endpoint1.

Points of entry are typically in the region of the apices of the teeth. equal pressure pointDuring forced exhalation, the point at an airway where the pressure inside the airway equals the intrapleural pressure. When the pleural pressure is greater than the pressure inside the airway, it tends to cause bronchiolar collapse.

The deep diffuse muscular pain is localized to a number of reproducible (from patient to patient) areas that are tender when palpated.
