e. Central. The term "central" is used to describe the mid-area or main part of
central: the mid-area or main part of an organ.
f. Distal. The term "distal" refers to those parts that are farthest from the
center, midline, or trunk. (In this sense, it is used as a directional term.) Distal can also
be used as a relational term to mean far from the source or beginning (figure 3-13).
Consider a patient as positioned in figure 3-13 (the lateral femur, distal and proximal).
Figure 3-13. The foot is distal to the hip, that is, far from the midline or trunk.
Figure 3-14. A lateral distal femur, is a side view of the part of the femur that is farthest
from the point of attachment.
