- Company Profile:
Three lines that transversely cross the cranial rear. From lowest to highest they are:
inferior nuchal line extends across the middle of the nuchal lane, separating the nuchal muscles semispinalis capitis above from rectus capitis below.
superior nuchal line the most prominent, develops along the top of the semispinalis capitis muscle and some of the muscles lying over it attach directly to the line, trapezius more centrally and sternocleidomastoid more laterally. It separates the nuchal from the occipital planes of the occiput.
supreme nuchal line lies above the superior line, on the occipital plane. It may be totally absent, a distinct line dipping downward at the midline, or the superior border of the nuchal torus (if there is one).
Industry:Archaeology
A groove extending down from the lower rim of the mandibular foramen or from just below it.
Industry:Archaeology
A statistical procedure that determines what constitutes a significant difference between observed results and results expected on the basis of a particular hypothesis; a goodness-of-fit test.
Industry:Archaeology
Chromatin that may become condensed throughout the cell cycle and may contain genes that areinactivated when the chromatin becomes condensed.
Industry:Archaeology
One in which genotypes associate at random (i.e., with equal probabilities of mating between any two individuals of opposite sex).
Industry:Archaeology
Specific sequences (e.g., in baker's yeast, Saccharomyces cerevisiae) that, when included as part of an extrachromosomal, circular DNA molecule, confer on that molecule the ability to replicate autonomously.
Industry:Archaeology
The petrous portion of the temporal bone is the pyramid-shaped process that extends across the cranial base, housing the internal ear.
Industry:Archaeology
A dating technique that relies indirectly on radioactive decay, overlapping with radiocarbon in the time period for which it is useful, but also has the potential for dating earlier periods. It has much in common with electron spin resonance (ESR).
Industry:Archaeology
A projection found on the proximal ventral surface of a detached piece below the striking platform. Some researchers believe that a pronounced lip indicates the detached piece was removed with a soft hammer.
Industry:Archaeology
An important source of information on the reconstruction of prehistoric diets, this technique analyses the ratios of the principle isotopes preserved in human bone; in effect the method reads the chemical signatures left in the body by different foods. Isotopic analysis is also used in characterization studies.
