| basal layer of choroid | The transparent, nearly structureless inner layer of the choroid in contact with the pigmented layer of the retina. Synonym: basal lamina of choroid, basal layer of choroid, Bruch's membrane, Henle's membrane, lamina vitrea, vitreous lamella, vitreous membrane. (05 Mar 2000) |
| basal medium | <cell culture> An unsupplemented medium which promotes the growth of many types of microorganisms which do not require any special nutrient supplements. (15 Nov 1997) |
| basal membrane of saemicircular duct | The basal membrane underlying the epithelium of the saemicircular duct. Synonym: membrana basalis ductus saemicircularis, basal lamina of saemicircular duct. (05 Mar 2000) |
| basal metabolic rate | <biochemistry, biology> The metabolic rate as measured under basal conditions: 12 hours after eating, after a restful sleep, no exercise or activity preceding test, elimination of emotional excitement and occurring in a comfortable temperature. Acronym: BMR (15 Nov 1997) |
| basal metabolism | <biochemistry, biology> Heat production, or its measurement, of an organism at the lowest level of cell chemistry in an inactive, awake, fasting state. It may be determined directly by means of a calorimeter or indirectly by calculating the heat production from an analysis of the end products of oxidation within the organism or from the amount of oxygen utilised. (27 Jun 1999) |
| basal-nerved | <botany> Having the nerves radiating from the base; said of leaves. Source: Websters Dictionary (01 Mar 1998) |
| 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 part of pulmonary artery | <anatomy, artery> See: right pulmonary artery, left pulmonary artery. (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) |
