Frame of referenceIn physics and astronomy, a frame of reference (or reference frame) is an abstract coordinate system whose origin, orientation, and scale are specified by a set of reference points―geometric points whose position is identified both mathematically (with numerical coordinate values) and physically (signaled by conventional markers). For n dimensions, n + 1 reference points are sufficient to fully define a reference frame.
DimensionIn physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus, a line has a dimension of one (1D) because only one coordinate is needed to specify a point on it - for example, the point at 5 on a number line. A surface, such as the boundary of a cylinder or sphere, has a dimension of two (2D) because two coordinates are needed to specify a point on it - for example, both a latitude and longitude are required to locate a point on the surface of a sphere.
Glossary of medicineThis glossary of medical terms is a list of definitions about medicine, its sub-disciplines, and related fields. Aarskog–Scott syndrome – (AAS) A rare, inherited (X-linked) disease characterized by short stature, facial abnormalities, skeletal and genital anomalies. Abdomen – The part of the body between the chest and pelvis, which contains most of the tubelike organs of the digestive tract, as well as several solid organs. Abdominal external oblique muscle – The largest, and outermost, of the three flat muscles of the lateral anterior abdominal wall.
Clinical clerkshipClinical clerkships encompass a period of medical education in which students – medical, nursing, dental, or otherwise – practice medicine under the supervision of a health practitioner. In medical education, a clerkship, or rotation, refers to the practice of medicine by medical students (M.D., D.O., D.P.M) during their final year(s) of study. Traditionally, the first half of medical school trains students in the classroom setting, and the second half takes place in a teaching hospital.
