| collateral sulcus | A long, deep sagittal fissure on the undersurface of the temporal lobe, marking the border between the fusiform gyrus laterally and the hippocampal and lingual gyri medially; the great depth of the collateral sulcus results in a bulging of the floor of the occipital and temporal horn of the lateral ventricle, the collateral eminence. Synonym: sulcus collateralis, sulcus occipitotemporalis, collateral fissure, fissura collateralis, occipitotemporal sulcus. (05 Mar 2000) |
|---|---|
| collateral trigone | A triangular prominence of the floor of the lateral ventricle at the transition between occipital and temporal horn, continuous rostrally with the collateral eminence and, like the latter, caused by the deep penetration of the collateral sulcus from the ventral surface of the temporal lobe. Synonym: trigonum collaterale, trigone of lateral ventricle, trigonum ventriculi, ventricular trigone. (05 Mar 2000) |
| collateral vessel | A branch of an artery running parallel with the parent trunk, a vessel that runs in parallel with another vessel, nerve, or other long structure. Synonym: vas collaterale. (05 Mar 2000) |
| collectin | <protein> Family of collagenous lectins believed to play an important part in first line defence by binding to viruses and by opsonising yeasts and bacteria. Contain a collagen like region and a C type lectin domain. Pulmonary surfactant proteins A and D (SP A, SP D), CL 43, serum mannan binding protein (MBP) and conglutinin are all members of the family. Complement C1q is structurally related to the family. Medline, various (18 Nov 1997) |
| collecting tubule | The continuation of the tubulus seminifer contortus which becomes straight just before entering the mediastinum to form the rete testis. Synonym: tubulus renalis rectus, tubulus seminifer rectus, collecting tubule, straight tubule, tubulus rectus, tubulus rectus, vasa recta. (05 Mar 2000) |
| collectins | A family of molecules that recognise and opsonise microbes during the preimmune response of a host. (05 Mar 2000) |
| collective bargaining | The process of negotiation between representatives of an employee organization, association or union, and representatives of the employer. (12 Dec 1998) |
| collective group | <zoology> An aggregate of related species of which the generic position is uncertain. According to the Code, for the sake of taxonomic convenience, may be treated as a genus. Such a collective group does not require a type species. Assignment to a collective group is a temporary, convenient, identifying label. (09 Jan 1998) |
| collective-group name | 1. A name established expressly for a collective group. 2. A name established for a nominal genus or subgenus and later used for a collective group. (09 Jan 1998) |
| college admission test | Test designed to identify students suitable for admission into a graduate or undergraduate curriculum. (12 Dec 1998) |
| collenchyma | <plant biology> Plant tissue in which the primary cell walls are thickened, especially at the cell corners. Acts as a supporting tissue in growing shoots, leaves and petioles. Often arranged in cortical ribs, as seen prominently in celery and rhubarb petioles. Lignin and secondary walls are absent, the cells are living and able to grow. (18 Nov 1997) |
| Colles fracture | <orthopaedics> A common fracture of the distal radius at the wrist joint due to a fall on an outstretched hand. Colles fracture is also referred to as the silver fork deformity, because the distal fracture fragment is usually angulated upwards (dorsal angulation). The resultant bend in the wrist results in the familiar appearance of a fork. If the resultant fracture angulation is in the opposite direction (toward the palm) it is referred to as a Smith's fracture. (27 Sep 1997) |
| Colles' fascia | The membranous layer of the subcutaneous tissue in the urogenital region attaching posteriorly to the border of the urogenital diaphragm, at the sides to the ischiopubic rami, and continuing anteriorly onto the abdominal wall. Synonym: fascia perinei superficialis, Colles' fascia, Cruveilhier's fascia, membranous layer of superficial fascia. (05 Mar 2000) |
| colles' fracture | Fracture of the lower end of the radius in which the lower fragment is displaced posteriorly. (12 Dec 1998) |
| Colles' ligament | <anatomy> A triangular fibrous band extending from the aponeurosis of the external oblique to the pubic tubercle of the opposite side. See: aponeurosis of external abdominal oblique muscle. Synonym: ligamentum reflexum, Colles' ligament, fascia triangularis abdominis, reflex ligament, triangular fascia. (05 Mar 2000) |
