dens sapientiae (medicine)


dens sapientiae -->
third molar
Eighth permanent tooth in the maxilla and mandible on each side, making it the most posterior tooth in human dentition; usually erupts between the seventeenth and twenty-third years; the roots are often fused, the separation being marked only by grooves; because it tends to erupt in an anterosuperior direction, the lower third molar often becomes impacted against the lower second molar; it is common for one or more third molar to fail to develop.

Synonym: dens serotinus, molaris tertius, dens sapientiae, wisdom tooth.


molecular clock (medicine)


molecular clock


This term has two separate uses.

1. <molecular biology> The rate of fixation of mutations in DNA and thus times the rate of genetic diversification.

2. <cell biology> A biological system capable of maintaining up a timing rhythm or pulse. All such clocks are thought to be entrained by a natural oscillator such as the diurnal rhythm.
