| 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.

| 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) |
| Gennari's band | A prominent white line appearing in perpendicular sections of the visual cortex (Brodmann's area 17) at about mid-thickness of the cortical gray matter, corresponding to the particularly well developed outer line of Baillarger of that cortical area, and composed largely of tangentially disposed intracortical association fibres. Synonym: Gennari's band, Gennari's stria, stripe of Gennari. (05 Mar 2000) |
| Casparian band | <plant biology> Region of plant cell wall specialised to act as a seal to prevent back leakage of secreted material (analogous to tight junction between epithelial cells). Found particularly where root parenchymal cells secrete solutes into xylem vessels. (18 Nov 1997) |
| matrix band | A metal or plastic band secured around the crown of a tooth to confine restorative material to be adapted into a prepared cavity. (05 Mar 2000) |
| M band | Central region of the A band of the sarcomere in striated muscle. (18 Nov 1997) |
| Reil's band | One of the trabeculae carneae in the right ventricle of the heart; it carries part of the right branch of the A-V bundle from the septum to the anterior papillary muscle on the opposite wall of the ventricle. Synonym: trabecula septomarginalis, moderator band, Reil's band. (05 Mar 2000) |
| Meckel's band | The portion of the anterior ligament of the malleus that extends from the base of the anterior process through the petrotympanic fissure, to attach to the spine of the sphenoid. See: anterior ligament of malleus. Synonym: Meckel's ligament. (05 Mar 2000) |
| pecten band | A fibrous induration of the anal pecten resulting from passive congestion or a chronic form of inflammation in this region. (05 Mar 2000) |
| cervical rib and band syndrome | <syndrome> Very chronic axon loss brachial plexopathy, caused by compromise of the lower trunk fibres by a congenital band extending from a rudimentary cervical rib to the first thoracic rib; rare disorder, found mostly in young to middle-aged women, that presents with unilateral hand wasting and weakness, particularly involving the lateral thenar eminence; sometimes accompanied by intermittent discomfort along the medial forearm and hand. Synonym: cervical rib and band syndrome, classic cervical rib syndrome. (05 Mar 2000) |
| perioplic band | A narrow band of corium and underlying tela subcutanea proximal to the coronary band at the top of the hoof; the periople develops from it. (05 Mar 2000) |
| chromosome band | A region of darker or contrasting staining across the width of a chromosome; the pattern of band's is characteristic for most chromosomes. (05 Mar 2000) |
