Week 7 on human bones - Lab Report Example

Locate the spine and palpate along the edges with the subject recumbent, bony prominences would be felt. Easier in children and lean males (Sinnatamby). C7: relatively harder to locate and palpate, easier in adult, lean males, feels as the most prominent cervical spinous process, differentiated from C6 by its movement upon extension of the head (Sinnatamby). Curves of the spine: easy to locate and palpate in children and lean males, with the subject standing erect.

Just following the spine would reveal its curves in the cervical, thoracic, lumbar, sacral, and coccygeal regions, the last two regions being harder to locate and palpate (Drake, Vogl, and Mitchell). Several ribs: the upper ribs are easier to locate in males than in females, and overall easier to locate in lean people. They feel as bony arches alternating with shallow depressions (Moore). The sternocostal junction: once the sternum is located, the sternocostal junction is easy to locate by palpating at the edge of the body of the sternum, easier in lean males (Sinnatamby).

Posterior to anterior palpation of ribs: relatively difficult to palpate individual ribs posteriorly than anteriorly. Easier in lean males. Start from the sides of the thorax and palpate along the arches till the body of the sternum (Drake, Vogl, and Mitchell). The 12th rib: relatively hard to locate. First locate the xiphoid process which is hard to palpate itself, then move along the edge to the hanging ribs. Tender in children. Much easier to locate in lean males (Moore).

Jugular notch on manubrium: easier to locate, felt as a dip or a notch medially at the junction of the two clavicles. Easier in
