| basal nuclei | Nucleus of the cerebral hemisphere that originally included the caudate and lenticular nuclei, the claustrum and the amygdaloid body (complex); functionally the term basal nuclei now specifies the caudate and lenticular nuclei and adjacent cell groups having important connections therewith (subthalamic nucleus; substantia nigra, partes compacta and reticulata); amygdaloid complex now known to be part of the limbic system. Synonym: nuclei basales. (05 Mar 2000) |
| basal nucleus of Ganser | A large group of large cells in the innominate substance, ventral to the lentiform nucleus. Synonym: nucleus basalis of Ganser. (05 Mar 2000) |
| basal part of occipital bone | The part of the occipital bone that lies anterior to the foramen magnum and joins with the body of the sphenoid bone. Synonym: pars basilaris ossis occipitalis, basal part of occipital bone, basilar apophysis, basilar process of occipital bone, basilar process, basiocciput. (05 Mar 2000) |
| basal plate of neural tube | The ventral division of the lateral walls of the neural tube in the embryo; it contains neuroblasts giving rise to somatic and visceral motor neurons. Synonym: lamina basalis, basal plate of neural tube, lamina ventralis, ventral plate of neural tube. (05 Mar 2000) |
| basal ration | Minimal diet containing only essential components. (05 Mar 2000) |
| basal ridge | That portion of bone in either the maxilla or the mandible which surrounds and supports the teeth. (12 Dec 1998) |
| basal rod | <microbiology> Rod shaped intracellular organelle lying below the undulating membrane of Trichomonas. Generates active bending associated with local loss of birefringence at the bending zone, probably as a result of conformational change in the longitudinal lamellae. Major protein approximately 90 kD. (10 Nov 1998) |
| basal seat | That portion of the basal seat which supports the complete or partial denture base under occlusal load. Synonym: basal seat, denture-bearing area, denture-supporting area, stress-bearing area, supporting area, tissue-bearing area. (05 Mar 2000) |
| basal seat area | That portion of the oral structures which is available to support a denture. (05 Mar 2000) |
| basal skull fracture | <orthopaedics> A fracture involving the base of the cranium. This fracture is often difficult to detect clinically. Findings may include raccoon eyes, Battle's sign, haemotympanum and cerebrospinal fluid rhinorrhoea. Plain skull X-ray will often not reveal the basal skull fracture, making a CT scan or MRI the most reliable diagnostic investigation. (15 Nov 1997) |
| basal sphincter | The thickening of the circular muscular coat at the base of the ileal papilla at the terminal ileum. Synonym: sphincteroid tract of ileum. (05 Mar 2000) |
| basal squamous cell carcinoma | <tumour> A carcinoma of the skin which in structure and behaviour is considered transitional between basal cell and squamous cell carcinoma The term should not be used for the much more common keratotic variety of basal cell carcinoma, in which the tumour cells are of basal type but which contains small foci of abrupt keratinization. Synonym: basal squamous cell carcinoma. (05 Mar 2000) |
| 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) |
