Appendicular Skeleton Lab Part B:
Pelvic Girdle and Lower Limb
Prelab: The pelvic girdle consists of two coxae (hipbones) that articulate with each
other anteriorly at the pubic symphysis and posteriorly with the sacrum. Together, the
pelvic girdle, sacrum and the coccyx comprise the pelvis. The pelvis, itself, provides
support for the trunk of the body and provides attachments for the lower limbs.
The bones of the lower limb form a framework of the thigh, leg, and foot. Each
limb includes a femur, a patella, a tibia, a fibula, seven tarsals, five metatarsals, and
fourteen phalanges.
Purpose: To examine the bones of the pelvic girdle and lower limb and to identify the
major features of these bones.
Materials: textbook, human skeleton articulated, disarticulated human skeleton,
colored pencils
Procedure:
Part A: The Pelvic Girdle
1. Review the section entitled “Pelvic Girdle” in chapter 7 of “Hole’s” or “Bones of
the Pelvic Girdle” in chapter 5 of Marieb.
2. As a review activity label figures 1 and 2

4. Use colored pencils to distinguish individual bones in each figure 1-6 Use
different colors to represent the regions you are responsible for on the
practical.

Conclusion:
Part A: Complete the following statements.
1. The pelvic girdle consists of two ______________________________.
2. The head of the femur articulates with the ______________________________ of the
coxae.
3. The __________________________________________ is the largest portion of the coxa.
4. The pubic bones come together anteriorly to form the joint called the
_________________________________________.
5. The _______________________________________ is the portion of the ilium that causes
the prominence of the hip.
