| Det-6 | detroid-6 [human sternal marrow cells] |
|---|---|
| LLSB | left lower scapular border; left lower sternal border |
| LSB | least significant bit; left sternal border; left scapular border; long spike burst |
| LSE | left sternal edge |
| LUSB | left upper scapular border; left upper sternal border |
| sternal part of diaphragm | The small slip on each side that arises from the inner surface of the xiphoid process and inserts on the central tendon. Synonym: pars sternalis diaphragmatis. (05 Mar 2000) |
|---|---|
| sternal plane | A plane indicated by the front surface of the sternum. Synonym: planum sternale. (05 Mar 2000) |
| sternal puncture | Removal of bone marrow from the manubrium by needle. (05 Mar 2000) |
| sternal synchondroses | The cartilaginous junctions between the body of the sternum and the manubrium, and the xiphoid process; in domestic animals, there may be several, e.g., synchondrosis manubriosternalis, synchondrosis intersternebralis, and synchondrosis xiphosternalis. Synonym: synchondroses sternales, sternal joints. (05 Mar 2000) |
| adhering junction | <cell biology> A type of junction between cells forming tissues that are subjected to stretching and pulling, such as the skin. This type of junction provides very tight contact between adjacent cells and allows the cells to fuction as a unit. Belt desmosomes are attachment sites that circle the cell, and spot desmosomes are small points of attachment across the cells surface. (15 Jan 1998) |
| amelodental junction | Amelodentinal junction, rarely used terms for dentinoenamel junction. (05 Mar 2000) |
| amnioembryonic junction | The line of amniotic attachment to the periphery of the embryonic disk. (05 Mar 2000) |
| anorectal junction | Transition from rectum to anal canal; corresponds to the perineal flexure, or the level at which the gut perforates the pelvic diaphragm; here the rectal ampulla narrows abruptly into a narrow slip. (05 Mar 2000) |
| anterior junction line | Radiographic projection of the mediastinal tissue septum between the upper lobes behind the sternum. (05 Mar 2000) |
| A-V junction | Imprecisely defined zone surrounding and including the A-V node and the adjacent atrial and ventricular myocardium. (05 Mar 2000) |
| cardioesophageal junction | The abrupt transition from oesophageal mucosa to that of the cardiac portion of stomach, demarcated internally in the living by the z-line, and approximated externally by the cardiac notch. (05 Mar 2000) |
| gap junction | <cell biology> A junction between two cells consisting of many pores that allow the passage of molecules up to about 900D. Each pore is formed by an hexagonal array (connexon) of six transmembrane proteins (connexins) in each plasma membrane: when mated together the pores open, allowing communication and the interchange of metabolites between cells. Electrical synapses are gap junctions and metabolic cooperation depends upon the formation of gap junctions. (18 Nov 1997) |
| manubriosternal junction | The angle between the manubrium and the body of the sternum at the manubriosternal junction. Marks the level of the second costal cartilage (rib) for counting ribs or intercostal spaces. Denotes level of aortic arch, bifurcation of trachea, and T4/T5 intervertebral disc. Synonym: angulus sterni, Louis' angle, Ludwig's angle, manubriosternal junction. (05 Mar 2000) |
| rectosigmoid junction | <anatomy> The site where the sigmoid colon becomes the rectum; usually takes the form of an acute angle, demarcated externally by a discontinuation of appendices epiploicae, a spreading out of the teniae coli to completely encircle the rectum, and consequently, termination of the sacculations (haustrae) between the teniae. (05 Mar 2000) |
| cell junction | <cell biology> Specialised junctions between cells. See: adherens junctions, desmosomes, tight junctions, gap junctions. (26 Mar 1998) |
