| pectoral and abdominal anterior cutaneous branch of intercostal nerves | The ventral primary rami of spinal nerves T7-T11 (seventh to eleventh intercostal nerves), which supply the abdominal as well as the thoracic wall; innervate intercostal, subcostal, serratus posterior inferior, transversus abdominis, external and internal oblique, and rectus abdominis muscles, and provide sensory branches to the periphery of the diaphragm, and parietal pleura and peritoneum. Synonym: rami cutanei anteriores pectoralis et abdominalis nervorum intercostalium, ramus cutaneus anterior (pectoralis et abdominalis) nervorum thoracicorum, anterior cutaneous nerves of abdomen, pectoral and abdominal anterior cutaneous branch of intercostal nerves.

| descending anterior branch | The descending anterior branch of the superior lobar branches of the right and left pulmonry arteries. Synonym: ramus anterior descendens. (05 Mar 2000) |
| anterior part of anterior commissure of brain | The anterior part of the anterior or rostral commissure of the brain. Synonym: pars anterior commissurae rostralis, pars anterior commissurae anterioris cerebri. (05 Mar 2000) |
| basal | Pertaining to or situated near a base. (18 Nov 1997) |
| basal age | The highest mental age level of the Stanford-Binet intelligence scale at which all items are passed. (05 Mar 2000) |
| basal anaesthesia | Parenteral administration of one or more sedatives to produce a state of depressed consciousness short of a general anaesthesia. (05 Mar 2000) |
| basal area | <botany> The cross-sectional area of a tree trunk measured in square inches, square centimetres, etc., basal area is normally measured at 4.5 feet above ground level and is used as a measure of dominance, the most commonly used tool for measuring basal area is a diameter tape or a D-tape (then convert to basal area). (09 Oct 1997) |
| basal body | <cell biology> Structure found at the base of eukaryotic cilia and flagella consisting of a continuation of the nine outer sets of axonemal microtubules but with the addition of a C tubule to form a triplet (like the centriole). May be self replicating and serves as a nucleating centre for axonemal assembly. Anchored in the cytoplasm by rootlets. Synonymous with kinetosome. (18 Nov 1997) |
| basal body temperature | <biology> The temperature taken at its lowest point in the day, usually in the morning before getting out of bed. (09 Oct 1997) |
| basal bone | The osseus tissue of the mandible and maxillae except the alveolar processes. (05 Mar 2000) |
| basal cell | <pathology> General term for relatively undifferentiated cells in an epithelial sheet that give rise to more specialised cells act as stem cells). In the stratified squamous epithelium of mammalian skin the basal cells of the epidermis (stratum basale) give rise by an unequal division to another basal cell and to cells that progress through the spinous, granular and horny layers, becoming progressively more keratinised, the outermost being shed as squames. In olfactory mucosa the basal cells give rise to olfactory and sustentacular cells. In the epithelium of epididymis their function is unclear, but they probably serve as stem cells. (13 Nov 1997) |
| basal cell adenoma | <tumour> A benign tumour of major or minor salivary glands or other organs composed of small cells showing peripheral palisading. (05 Mar 2000) |
| basal cell carcinoma | <oncology, tumour> The most common form of skin cancer. A malignant growth of epidermal tissue, specifically basal cells. most common in the fair-skinned on sun-exposed areas (especially the face). (15 Nov 1997) |
| basal cell epithelioma | <oncology, tumour> The most common form of skin cancer. A malignant growth of epidermal tissue, specifically basal cells. most common in the fair-skinned on sun-exposed areas (especially the face). (15 Nov 1997) |
| basal cell hyperplasia | Increase in the number of cells in an epithelium resembling the basal cells. (05 Mar 2000) |
