| splitting | In chemistry, the cleavage of a covalent bond, fragmenting the molecule involved. (05 Mar 2000) |
|---|---|
| splitting enzymes | Enzyme's that, like aldolases, catalyze the conversion of a molecule into two smaller molecules without the addition or subtraction of any atoms. (05 Mar 2000) |
| splitting of heart sounds | The production of major components of the first and second heart sounds (rarely the third and fourth) due to contribution by the left-sided and right-sided valves; thus, the first heart sound would have a mitral and a tricuspid component and the second heart sound has an aortic and pulmonic component. The latter are best appreciated during respiration, with inspiration delaying the pulmonic component and producing an earlier aortic component. (05 Mar 2000) |
| kinase-splitting membranal proteinase | <enzyme> Brush-border membrane proteinase; specifically clips the native form of the catalytic subunit of camp-dependent protein kinase Registry number: EC 3.4.99.- Synonym: ksm proteinase (26 Jun 1999) |
| alveolar arch of mandible | The free margin of the alveolar process of the mandible. Synonym: arcus alveolaris mandibulae, limbus alveolaris. (05 Mar 2000) |
| alveolar part of mandible | The portion of the body of the mandible that surrounds and supports the lower teeth. Synonym: pars alveolaris mandibulae. (05 Mar 2000) |
| angle of mandible | <anatomy> The angle formed by the lower margin of the body and the posterior margin of the ramus of the mandible. Synonym: angulus mandibulae, angle of jaw. (05 Mar 2000) |
| base of mandible | The rounded inferior border of the body of the mandible. Synonym: basis mandibulae. (05 Mar 2000) |
| body of mandible | The heavy, U-shaped, horizontal portion of the mandible extending posteriorly to the angle where it is continuous with the ramus; it supports the lower teeth. Synonym: corpus mandibulae. (05 Mar 2000) |
| ramus of mandible | The upturned perpendicular extremity of the mandible on either side; it gives attachment on its lateral surface to the masseter muscle. Synonym: ramus mandibulae. (05 Mar 2000) |
| ramus of the mandible | The mandible (the lower jaw bone) is shaped like a horseshoe. The back parts of the horseshoe that stick up are the two ramuses, or more properly, the rami of the mandible. (12 Dec 1998) |
| mandible | The jaw bone. (27 Sep 1997) |
| head of mandible | The expanded articular portion of the condylar process of the mandible. Synonym: caput mandibulae. (05 Mar 2000) |
| neck of mandible | The constricted portion of the condylar process below the head of the mandible. Synonym: collum mandibulae. (05 Mar 2000) |
| oblique line of mandible | The line on the external surface of the mandible that extends from the mental tubercle to the ramus and separates the alveolar and basilar parts of the bone. Synonym: linea obliqua mandibulae. (05 Mar 2000) |
