Week 7 on human bones - Lab Report Example

elatively harder to locate and palpate, easier in subject 1, feels as the most prominent cervical spinous process, differentiated from C6 by its movement upon extension of the head (Sinnatamby 450). Curves of the spine: easy to locate and palpate in children and in subject 1, 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 both in subject 1 and 2 (Drake, Vogl, and Mitchell 83).

Several ribs: the upper ribs are easier to locate in subject 1 than in subject 2, and overall easier to locate in lean people. They feel as bony arches alternating with shallow depressions (Drake, Vogl, and Mitchell 147). Posterior to anterior palpation of ribs: relatively difficult to palpate individual ribs posteriorly than anteriorly. Easier in subject 1. Start from the sides of the thorax and palpate along the arches till the body of the sternum (Drake, Vogl, and Mitchell 143). 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 subject 1 ((Sinnatamby 187). Body of the sternum: easy to locate, especially in children and in subject 1. Felt as a flat bone in the center of the chest or thorax. Ends suddenly in a dip, which is the xiphoid process (Sinnatamby 226). Xiphoid process: relatively hard to locate and palpate. Easier in children and in subject 1. Felt as a sudden dip at the end of the body of sternum.

Once located, it is easier to palpate the hanging ribs (Sinnatamby 226). The sacrum: relatively harder to locate, but easy to palpate. Easier in children and in subject 1, and with the subject sitting, feels as a continuation of bony spines running along the entire length of the bone caudally from the spine midway between the two PSISs (Drake, Vogl, and Mitchell
