| band 3 protein | A ubiquitous membrane transport protein found in the plasma membrane of diverse cell types and tissues, and in nuclear, mitochondrial, and golgi membranes. It is the major integral transmembrane protein of the erythrocyte membrane, comprising 25% of the total membrane protein and occurring at 1 million copies per cell. It exists as a dimer and provides a channel for the transport of anions across the membrane. (12 Dec 1998) |

| band cell | <pathology> Immature neutrophils released from the bone marrow reserve in response to acute demand. (18 Nov 1997) |
| band centrifugation | <technique> High-speed centrifugation inwhich molecules float at a point wheretheir density equals that in a gradient of cesium chloride or sucrose. (12 Jan 1998) |
| band III protein | <protein> A 90 kD protein embedded in the surface of the human erythrocyte membrane, identified as the major anion transport/exchange protein. When the red blood cell is in the lungs, brings chlorine ion into the cell in exchange for bicarbonate. Analogous proteins exist in other erythrocytes. A dimeric transmembrane glycoprotein, with binding sites for many cytolasmic proteins, including ankyrin, on its cytoplasmic domain. (18 Nov 1997) |
| band neutrophil | <pathology> Immature neutrophils released from the bone marrow reserve in response to acute demand. (18 Nov 1997) |
| band of Giacomini | A slender whitish band, the attenuated anterior continuation of the dentate gyrus (fascia dentata), crossing transversally the surface of the recurved part of the uncus gyri parahippocampalis. Synonym: band of Giacomini, cauda fasciae dentatae, frenulum of Giacomini, tail of dentate gyrus. (05 Mar 2000) |
| band of Kaes-Bechterew | A band of horizontal myelinated fibres in the most superficial part of the third layer of the isocortex. Synonym: Bechterew's band, layer of Bechterew, line of Bechterew, line of Kaes. (05 Mar 2000) |
| band remover | <dentistry> A special plier which the orthodontist uses to remove bands from your teeth (08 Jan 1998) |
| band-shaped keratopathy | A horizontal, gray, interpalpebral opacity of the cornea that begins at the periphery and progresses centrally; occurs in hypercalcaemia, chronic iridocyclitis, and Still's disease. (05 Mar 2000) |
| Bechterew's band | A band of horizontal myelinated fibres in the most superficial part of the third layer of the isocortex. Synonym: Bechterew's band, layer of Bechterew, line of Bechterew, line of Kaes. (05 Mar 2000) |
| Broca's diagonal band | A white fibre bundle descending in the precommissural septum toward the base of the forebrain, immediately rostral to the lamina terminalis; at the base, the bundle turns in the caudolateral direction; traveling through a ventral stratum of the innominate substance alongside the optic tract, it fades before reaching the amygdala. (05 Mar 2000) |
| Mach's band | A relatively bright or dark band perceived in a zone where the luminance increases or decreases rapidly. (05 Mar 2000) |
| Maissiat's band | A fibrous reinforcement of the fascia lata on the lateral surface of the thigh, extending from the crest of the ilium to the lateral condyle of the tibia. Synonym: tractus iliotibialis, iliotibial band, Maissiat's band. (05 Mar 2000) |
| ventricular band of larynx | One of the pair of folds of mucous membrane stretching across the laryngeal cavity from the angle of the thyroid cartilage to the arytenoid cartilage; they enclose a space called the rima vestibuli or false glottis. Synonym: plica vestibularis, false vocal cord, plica ventricularis, ventricular band of larynx, ventricular fold. (05 Mar 2000) |
| marginal band | A bundle of equatorially located microtubules that stabilise the biconvex shape of platelets and avian erythrocytes. They are unusual in that they do not derive from the centrosomal microtubule organising centre. (18 Nov 1997) |
