|---|---|
| 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) |
| parietal bone | The side bone of the skull. (12 Dec 1998) |
| parietal border | Edge of a bone which articulates with the parietal bone. See: parietal border of frontal bone, parietal border of sphenoid bone, parietal border of temporal bone. Synonym: margo parietalis, parietal margin. (05 Mar 2000) |
| parietal border of frontal bone | The margin of the frontal bone that articulates with the parietal bone. Synonym: margo parietalis ossis frontalis. (05 Mar 2000) |
| parietal border of sphenoid bone | The margin of the greater wing of the sphenoid that articulates with the parietal bone. Synonym: margo parietalis ossis sphenoidalis. (05 Mar 2000) |
| parietal border of temporal bone | The border of the squamous part of the temporal bone that articulates with the parietal bone. Synonym: margo parietalis ossis temporalis. (05 Mar 2000) |
| parietal branch | Branches coursing in relationship to and supplying the parietal bone or parietal lobe of cerebrum, branches distributed to the body wall and limbs (the "parities") as opposed to visceral branches distributed to the body cavities. For example, the gray rami communicantes are the parietal branches of the sympathetic trunks (vs. The splanchnic nerves, which are visceral branches of the trunks). Synonym: rami parietales. (05 Mar 2000) |
| parietal branch of medial occipital artery | <anatomy, artery> An anterior branch of the medial occipital artery supplying the posterior section of the parietal lobe of the cerebrum. Synonym: ramus parietalis arteriae occipitalis medialis. (05 Mar 2000) |
| parietal branch of middle meningeal artery | <anatomy, artery> Smaller terminal branch (with frontal branch) of middle meningeal artery supplying posterior portion of lateral and superior dura and cranium. Synonym: ramus parietalis arteriae meningeae mediae. (05 Mar 2000) |
| parietal branch of superficial temporal artery | <anatomy, artery> Branches coursing in relationship to and/or supplying the parietal lobe of the brain. Synonym: ramus parietalis arteriae temporalis superficialis. (05 Mar 2000) |
| parietal cell | One of the cell's of the gastric glands; it lies upon the basement membrane, covered by the chief cell's, and secretes hydrochloric acid that reaches the lumen of the gland through fine intracellular and intercellular canals (canaliculi). Synonym: acid cell, oxyntic cell. (05 Mar 2000) |
| parietal cells, gastric | Cells of the gastric glands which secrete hydrochloric acid and intrinsic factor. (12 Dec 1998) |
| parietal eminence | A prominent portion of the parietal bone, a little above the centre of its external surface, usually corresponding to the point of maximum width of the head. Synonym: tuber parietale, eminentia parietalis, parietal tuber. (05 Mar 2000) |
