nursing process see nursing process.
odontoid process a toothlike projection of the axis that articulates with the atlas.
pterygoid process either of the two processes of the sphenoid bone, descending from the points of junction of the great wings and the body of the bone, and each consisting of a lateral and a medial plate.
spinous process of vertebra a part of a vertebra projecting backward from the arch, giving attachment to muscles of the back.
styloid process a long, pointed projection, particularly a long spine projecting downward from the inferior surface of the temporal bone.
temporal process the posterior blunt process of the zygomatic bone that articulates with the zygomatic process of the temporal bone to form the zygomatic arch.
uncinate process any hooklike process, as of vertebrae, the lacrimal bone, or the pancreas.
xiphoid process the pointed process of cartilage, supported by a core of bone, connected with the lower end of the sternum; called also xiphoid.

Performing a combined ranking of accuracy and precision of the 5 analyzed indicators in two groups, it appears that the best indicators in subjects without severe malnutrition in their cause of death was ridges and occipital bone size and roughness of the mastoid process, while the group with severe malnutrition in their cause of death was the best indicator aspect of the zygomatic bone.
Table 2 shows the distance between the asterion and the Henle spine and the distance between the asterion and the mastoid process. The midpoint between the asterion and the mastoid process marked the lower edge of the sigmoid sinus in 19 out of the 20 sides (95%), whereas in 1 side (5%), it marked the position of the sigmoid sinus.
Jonckheere-Terpstra tests indicated an increase in cranial scores with increasing age, with the exception of male mastoid process scores, although the maximum percent of variance in any single trait score for the entire sample that was explained by age was less than 13% according to Spearman's rank correlation analyses (Garvin et al.
The posterior auricular artery emerges from the deeper tissues in the groove between the cartilage of the ear and the mastoid process (Fig.
During the operation, purulent secretion and eroded bone should be removed, clearing the involved air cells of the zygomatic root as well as the mastoid process.
The sensors were positioned at the following anatomical points (Figure 1(a)): (1) right mastoid process (reference sensor); (2) left mastoid process (reference sensor); (3) glabella (reference sensor); (4) upper incisor (between the two upper central incisors) (reference sensor); (5) lower incisor (between the two lower central incisors) (movement sensor).
Each one was labeled with an Arabic number on the left mastoid process. Then, using the definition by Testut & Latarjet, the researchers proceeded to identify the presence or absence of the infratemporal spine and delimit it.
The age, sex, height, body mass index (Weight in Kg divided by the square of the height in metres), the circumference of the neck at the thyroid prominence and the distance from the suprasternal notch to the right mastoid process was measured.
The present authors are unaware of any studies that addressed the accuracy of C1 TVP palpation in relation to its contiguous structures, the mastoid process and the transverse process (TVP) of C2.
The posterior branch supplies the skin over the mastoid process and lower external ear, while the anterior branch supplies the skin overlying the parotid gland and lower preauricular region.
