Does the projection move? ______ (yes or no) (c) Which bone belongs to this projection? ___________________________________ In general, to identify a portion of a bone near a joint, move the body parts adjacent to the joint while touching the bone. Identify the bones that have the surface features listed in Table 39-2 on page 10. Table 39-2 Features and Bones Surface Feature Bone Knuckles Bump next to the wrist and on the same side of the upper appendage as the little finger Smaller bump next to the wrist and on the same side of the upper appendage as the thumb Bump next to and outside the ankle Bump next to and inside the ankle D. Structure of a bone 1. Look at the femur, the longest bone of the skeleton (Fig. 39-10). It consist of shaft, or diaphysis, with two knobby ends, or epiphyses (singular, epiphysis). One end has a narrow neck and a round head. Which bone does the femur join? __________________________________________________ (b) To which bone of the skeleton does the other end join? ________________________________ Note the other surface features on the femur, such as projections of various sizes and lines. These surface features are attachment sites for tendons and ligaments. Are these small tunnels openings onto the surface of the femur? __________ (yes or no)
