| communicating branch of otic ganglion with meningeal branch of mandibular nerve | <anatomy, nerve> A branch of otic ganglion to the meningeal branch of mandibular nerve conveying postsynaptic parasympathetic fibres which run back to the main stem of the mandibular nerve for distribution to the parotid gland via the auriculotemporal nerve. Synonym: ramus communicans ganglii otici cum ramo meningeo nervi mandibularis. (05 Mar 2000) |

| posterior branch of right branch of portal vein | <anatomy, vein> Posterior segmental branch of portal vein; branch to posterior segments of right lobe of liver. Synonym: ramus posterior rami dextri venae portae hepatis. (05 Mar 2000) |
| superior lingular branch of lingular branch of superior lobar left pulmonary artery | <anatomy, artery> Branch (of the lingular branch) of the left pulmonary artery serving the superior lingular segment of the superior lobe of the left lung. Synonym: ramus lingularis superior. (05 Mar 2000) |
| inferior lingular branch of lingular branch of left pulmonary artery | <anatomy, artery> Branch (of the lingular branch) of the left pulmonary artery serving the inferior lingular segment of the superior lobe of the left lung. Synonym: ramus lingularis inferior. (05 Mar 2000) |
| anterior basal segment | Anterior basal segment of inferior lobe of right and left lung; lies between middle lobe and diaphragm. Synonym: segmentum basale anterius. (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) |
