Question

Pre-Lab #4 (This will help you prepare for the Skeletal Anatomy Test at end of Week 5).

• Diagram (or obtain an unlabeled digital image of) and label the bones below. You can obtain unlabeled images online.

  • For each bone complete the following tasks for Pre-Lab #4
    • Identify the bone and whether it is right or left (if that applies).
    • Identify any markings or structures listed below on the bone (ex: fossa, cavity, process, etc).
    • Identify any specific joints/articulations this bone is found in and other bones involved in the articulation.
    • Explain how to differentiate between a male and female pelvis.

Answer 1

Human skeleton made up of 206 bones.It functions as a support system of the body, gives the shape of the body, provides protection to organs and other systems of the body, to provide attachments for muscles, to produce movement and to produce Red blood cells.

The pelvis is one of the most useful skeletal element for differentiating between male and female. Female pelves are larger and wider than male pelves and have round pelvic inlet. The male iliac crest is higher than female, causing their false pelves to look taller and narrower.

Below are labeled the diagram.
