The
forearm refers to the region of the
upper limb between the
elbow and the
wrist. The term forearm is used in
anatomy to distinguish it from the arm, a word which is most often used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower "arm" is called the forearm. It is to the region of the
leg that lies between the
knee and the
ankle joints, the
crus.
