| 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) |
| Clado's band | The suspensory ligament of the ovary. (05 Mar 2000) |
| moderator 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) |
| contraction band | A microscopic change in myocardial cells in which excessive contraction, associated with elevated intracellular calcium and serum norepinephrine, causes the formation of transverse amorphous band's in the fibres which are then incapable of contracting again. Synonym: contraction band necrosis. (05 Mar 2000) |
| contraction band necrosis | A microscopic change in myocardial cells in which excessive contraction, associated with elevated intracellular calcium and serum norepinephrine, causes the formation of transverse amorphous band's in the fibres which are then incapable of contracting again. Synonym: contraction band necrosis. (05 Mar 2000) |
| coronary band | A region of the pododerm; a prominent ridge of corium and underlying tela subcutanea at the top of the hoof from which most of the wall of the hoof grows. Synonym: corium coronae. (05 Mar 2000) |
| h band | <cell biology> The H band is an area within muscle tissue which is light when stained and consists only of myosin fibres (and no actin fibres). The H band is at the centre of each muscle sarcomere. (09 Oct 1997) |
| Schilling's band cell | <pathology> Immature neutrophils released from the bone marrow reserve in response to acute demand. (18 Nov 1997) |
| His' band | The bundle of modified cardiac muscle fibres that begins at the atrioventricular node as the trunk of the atrioventricular bundle and passes through the right atrioventricular fibrous ring to the membranous part of the interventricular septum where the trunk divides into two branches, the right crus of the atrioventricular bundle and the left crus of the atrioventricular bundle; the two crura ramify in the subendocardium of their respective ventricles. Synonym: fasciculus atrioventricularis, atrioventricular band, Gaskell's bridge, His' band, His' bundle, bundle of His, Keith's bundle, Kent's bundle, Kent-His bundle, ventriculonector. (05 Mar 2000) |
| silastic band | A small silastic ring placed around each fallopian tube to achieve permanent sterilization. (05 Mar 2000) |
| Soret band | The absorption band of all porphyrins at about 400 nm. (05 Mar 2000) |
| I band | <cell biology> The isotropic band of the sarcomere of striated muscle, where only thin filaments are found. Unlike the A band, the I band can vary in width depending upon the state of contraction of the muscle when fixed. (18 Nov 1997) |
| iliotibial 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) |
