| basal striations | The vertical infranuclear striation's due to the infolded plasma membrane and mitochondria; they are seen in kidney tubules and certain intralobular salivary ducts. (05 Mar 2000) |

| basal surface | The surface of the denture of which the detail is determined by the impression and which rests upon the basal seat. (05 Mar 2000) |
| basal tentorial branch of internal carotid artery | <anatomy, artery> A small branch from the cavernous part of the internal carotid artery to the base of the tentorium. Synonym: ramus basalis tentorii arteriae carotidis internae. (05 Mar 2000) |
| basal tuberculosis | Tuberculosis of the basilar portions of the lungs. (05 Mar 2000) |
| basal veins | See: basal vein of Rosenthal, common basal vein, inferior basal vein, superior basal vein. (05 Mar 2000) |
| carcinoma, basal cell | A malignant skin neoplasm that seldom metastasizes but has potentialities for local invasion and destruction. Clinically it is divided into types: nodular, cicatricial, morphaic, and erythematoid (pagetoid). More than 95% of these carcinomas occur in patients over 40. They develop on hair-bearing skin, most commonly on sun-exposed areas. Approximately 85% are found on the head and neck area and the remaining 15% on the trunk and limbs. (12 Dec 1998) |
| rate, basal metabolic | A measure of the rate of metabolism. For example, someone with an overly active thyroid will have an elevated basal metabolic rate. (12 Dec 1998) |
| relative basal area | An estimate of basal area for trees, such as produced by the Bitterlich sampling technique. (09 Oct 1997) |
| medial basal branch of pulmonary artery | <anatomy, artery> A branch of the basal part of inferior lobar branches of the left and right pulmonary arteries. Synonym: ramus basalis medialis. (05 Mar 2000) |
| medial basal segment | Cardiac segment; medial basal segment of inferior lobe of right and left lung; can only be seen from medial and inferior surfaces since it does not reach lateral surface of lung. Synonym: segmentum basale mediale, segmentum cardiacum, cardiac segment. (05 Mar 2000) |
| Weil's basal layer | The layer beneath the odontoblasts of the tooth; it contains reticular fibres but few if any cells. Synonym: Weil's basal zone. (05 Mar 2000) |
| Weil's basal zone | The layer beneath the odontoblasts of the tooth; it contains reticular fibres but few if any cells. Synonym: Weil's basal zone. (05 Mar 2000) |

| posterior basal segment | Posterior basal segment of inferior lobe of right and left lungs; lies adjacent to vertebral column below superior segment. Synonym: segmentum basale posterius. (05 Mar 2000) |
| neoplasms, basal cell | Neoplasms composed of cells from the deepest layer of the epidermis. The concept does not refer to neoplasms located in the stratum basale. (12 Dec 1998) |
