# basal

basal (ba´sal)

1. Situated nearer the base of a pyramid-shaped organ in relation to a specific reference point; opposite of apical.basalis [NA]; 2. In dentistry, denoting the floor of a cavity in the grinding surface of a tooth. 3. Denoting a standard or reference state of a function, as a basis for comparison. More specifically, denoting the exact conditions for measurement of basal metabolic rate (q.v.); b. conditions do not always denote a minimum value, e.g., metabolic rate in sleep is usually less than the b. rate, but is inconvenient for standard measurement.
