Terrestrial animals using their soles for locomotion are called plantigrade. In chimpanzees, the soles are furrowed with creases deeper and more distinct than in their palms. In the palms, the pattern density is thickest in the central part, but in the sole, the density is thickest near the big toe whilst a large part of the remaining sole is ...
The leg of a plantigrade mammal includes the bones of the upper leg (femur/humerus) and lower leg (tibia and fibula/radius and ulna). The leg of a digitigrade mammal also includes the metatarsals / metacarpals , the bones that in a human compose the arch of the foot and the palm of the hand.
The leg (between the knee and the ankle) is the crus and crural area, the lateral aspect of the leg is the peroneal area, and the calf is the sura and sural region. The ankle is the tarsus and tarsal, and the heel is the calcaneus or calcaneal.
The pelvis and legs contain, from superior to inferior, the inguinal or groin region between the thigh and the abdomen, the pubic region surrounding the genitals, the femoral region encompassing the thighs, the patellar region encompassing the front of the knee, the crural region encompassing the lower leg, between the knee and ankle,
Anatomists restrict the term leg to this use, rather than to the entire lower limb. [6] The thigh is between the hip and knee and makes up the rest of the lower limb. [1] The term lower limb or lower extremity is commonly used to describe all of the leg. The leg from the knee to the ankle is called the crus. [7]
The cranial pair (i.e. closer to the head) of limbs are known as the forelimbs or front legs, and the caudal pair (i.e. closer to the tail or coccyx) are the hindlimbs or back legs. In animals with a more erect bipedal posture (mainly hominid primates, particularly humans), the forelimbs and hindlimbs are often called upper and lower limbs ...

When the legs are splayed at the hip, such as when doing a star jump or doing a split, the legs are abducted at the hip. [3] Adduction is a motion that pulls a structure or part towards the midline of the body, or towards the midline of a limb, carried out by one or more adductor muscles. In the case of fingers and toes, it is bringing the ...
