| propagated thrombus | A gradually increasing thrombosis involving one section of a vein after another in continuity. (05 Mar 2000) |
|---|---|
| secondary thrombus | A thrombus formed about an embolus as a nucleus. (05 Mar 2000) |
| hyaline thrombus | A translucent colourless plug, partly or wholly filling a capillary or small artery or vein, formed by agglutination of red blood corpuscles. Synonym: agglutinative thrombus. (05 Mar 2000) |
| stratified thrombus | A laminated thrombus, the layers of different ages being of different colour or consistency. Synonym: stratified thrombus. (05 Mar 2000) |
| infective thrombus | A thrombus formed in septic phlebitis. (05 Mar 2000) |
| obstructive thrombus | A thrombus due to obstruction in the vessel from compression or other cause. (05 Mar 2000) |
| thrombus | <haematology> An aggregation of blood factors, primarily platelets and fibrin with entrapment of cellular elements, frequently causing vascular obstruction at the point of its formation. Some authorities thus differentiate thrombus formation from simple coagulation or clot formation. Compare: embolism. Origin: Gr. Thrombos = clot (18 Nov 1997) |
| fibrin thrombus | A thrombus formed by repeated deposits of fibrin from the circulating blood; it usually does not completely occlude the vessel. (05 Mar 2000) |
| laminated thrombus | A thrombus formed gradually by clotting of the blood in successive layers. (05 Mar 2000) |
| anterior parietal artery | <anatomy, artery> The branch distributed to the anterior part of the parietal lobe. Synonym: arteria parietales anterior. (05 Mar 2000) |
| ascending parietal convolution | The anterior convolution of the parietal lobe, bounded in front by the central sulcus (fissure of Rolando) and posteriorly by the interparietal sulcus. Synonym: gyrus postcentralis, ascending parietal convolution, ascending parietal gyrus, posterior central convolution, posterior central gyrus. (05 Mar 2000) |
| ascending parietal gyrus | The anterior convolution of the parietal lobe, bounded in front by the central sulcus (fissure of Rolando) and posteriorly by the interparietal sulcus. Synonym: gyrus postcentralis, ascending parietal convolution, ascending parietal gyrus, posterior central convolution, posterior central gyrus. (05 Mar 2000) |
| parietal | 1. <anatomy> Of or pertaining to the walls of a cavity. 2. Pertaining to or located near the parietal bone, as the parietal lobe. (18 Nov 1997) |
| parietal angle | An angle formed by the meeting of the prolongation of two lines tangential to the most prominent part of the zygomatic arch and to the parietofrontal suture on each side; when the lines remain parallel the angle is zero; when they diverge it is negative. Synonym: Quatrefages' angle. (05 Mar 2000) |
| parietal arteries | Branches of the terminal part of the middle cerebral artery, divided into two branches: anterior parietal artery and posterior parietal artery. Synonym: arteriae parietales. (05 Mar 2000) |
