Organization of the Skeleton
Prelab: the skeleton can be divided into two major portions: (1) axial skeleton, which
consists of the bones and cartilages of the head, neck, and trunk, and (2) the
appendicular skeleton, which consists of the bones of the limbs and those that
anchor the limbs to the axial skeleton.
Purpose: To review the organization of the skeleton, the major bones of the skeleton,
and the terms used to describe the skeletal structures.
Materials: textbook, articulated human skeleton, colored pencils
Procedure:
1. Review the section entitled “Skeletal Organization” in chapter 7 of “Hole’s” [p.
121-139 in Marieb]

4. Examine the human skeleton and locate the following parts. As you locate the
following bones, note the number of each in the skeleton. Palpate as many of
the corresponding bones in your own skeleton as possible.

5. Study table 5.1 in Marieb or Table 7.2 in “Hole’s”. Locate an example of each
of the following features (bone markings) on the bone listed. Noting the size,
shape, and location in the human skeleton.
Condyle – occipital
Crest – tibia, hipbones
Epicondyle- Femur
Facet – vertebra
Foramen- skull
Fossa – humerus
Head – humerus
Meatus – temporal
Sinus – skull
Spine – scapula
Suture – skull
Trochanter – femur
Tubercle – humerus
Tuberosity - tibia
Ramus (armlike bar of bone) mandible)- mandible
6. Complete the conclusion questions.

Conclusion:
Part A
1. The cranium and facial bones compose the _________________________________.
2. The ____________________________ bone supports the tongue.
3. The ____________________________ at the inferior end of the sacrum is composed
of several fused vertebrae.
4. Most ribs are attached anteriorly to the __________________________________.
5. The thoracic cage is composed of _______________________pairs of ribs.
6. The scapulae and the clavicles together form the
_______________________________________.
7. The humerus, radius, and ____________________________________ articulate to
form the elbow joint.
8. The wrist is composed of eight bones called _________________________________.
9. The coxae (hipbones) are attached posteriorly to the ________________________.
10. The pelvic girdle (coxae), sacrum, and coccyx together form the
