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 ...
The leg is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or buttock region. The major bones of the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula. There are 60 bones in each leg. The thigh is located in between the hip and knee.
A hindlimb or back limb is one of the paired articulated appendages attached on the caudal end of a terrestrial tetrapod vertebrate's torso. [1] With reference to quadrupeds , the term hindleg or back leg is often used instead.
A long bone is one that is cylindrical in shape, being longer than it is wide. However, the term describes the shape of a bone, not its size, which is relative. Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges).
Zygomatic bones: attach to the temporal bone to form the zygomatic arch (cheek bone) Palatine bones: form the back of the hard palate; Sphenoid bone: formed by fusion of the foetal basisphenoid and presphenoid bones, at the base of the skull. Can become fractured in horses that rear over backwards. Vomer: forms the top of the inside of the ...
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
The implication that the ancestors of snakes had hind legs is confirmed by fossil evidence: the Cretaceous snake Pachyrhachis problematicus had hind legs complete with hip bones (ilium, pubis, ischium), thigh bone , leg bones (tibia, fibula) and foot bones (calcaneum, astragalus) as in tetrapods with legs today.

For a front leg, this is when the lower leg is in front of the horse, i.e. angled forward, while the caudal phase is when the leg is underneath the horse, i.e. angled backward. For a hind leg, the cranial phase occurs when the lower leg is under the body of the horse, and the caudal phase is when the limb is out behind the body of the horse.
