On the basis of morphological burials as the mastoid process, the jaw, wears and biological characteristics of their teeth it is inferred that these belong to a young female specimen, aged 18 to 21 years approximately.
22.
It arises by tendons from the transverse processes of the upper four or five thoracic vertebrae, and the articular processes of the lower three or four cervical vertebrae, and is inserted into the posterior margin of the mastoid process, beneath the splenius capitis and sternocleidomastoid.
23.
The fibers of the muscle are directed upward and laterally and are inserted, under cover of the sternocleidomastoideus, into the mastoid process of the temporal bone, and into the rough surface on the occipital bone just below the lateral third of the superior nuchal line.
24.
The eleventh or spinal accessory nerve corresponds to a line drawn from a point midway between the angle of the jaw and the mastoid process to the middle of the posterior border of the sterno-mastoid muscle and thence across the posterior triangle to the deep surface of the trapezius.

Ashley Montagu said that the San have the following neotenous traits relative to Caucasoids : large brain, light skin pigment, less hairy, round-headed, bulging forehead, small cranial sinuses, flat roof of the nose, small face, small mastoid processes, wide eye separation, median eye fold, short stature and horizontal penis.

"Ashley Montagu noted that Bushmen have the following neotenous traits relative to Caucasoids : " large brain ", light skin pigment, less hairy, round-headed, bulging forehead, small cranial sinuses, flat roof of the nose, small face, small mastoid processes, wide eye separation, median eye fold, short stature and horizontal penis"
27.
The new species belongs to the Lutrinae because of its possession of a large infraorbital canal and ventral expansion of the mastoid process, among other traits . " Siamogale melilutra " was about the size of a wolf and weighed as much as 50 kg ( more than 100 pounds ).
28.
A normal or "'positive Rinne "'test is when the sound heard outside the ear ( air conduction or AC ) is louder than the initial sound heard when the tuning fork end is placed against the skin on top of the mastoid process behind the ear ( bone conduction or BC ).
29.
It next ascends to the interval between the transverse process of the atlas and the mastoid process of the temporal bone, and passes horizontally backward, grooving the surface of the latter bone, being covered by the sternocleidomastoideus, splenius capitis, longissimus capitis, and digastricus, and resting upon the rectus capitis lateralis, the obliquus superior, and semispinalis capitis.
30.
The tympanic antrum is bounded above by a thin plate of bone, the tegmen tympani, which separates it from the middle fossa of the base of the skull; below by the mastoid process; laterally by the squama just below the temporal line, and medially by the lateral semicircular canal of the internal ear which projects into its cavity.
