Paw 肉垫
A paw is the soft foot of a mammal, generally a quadruped, that has claws.
The paw is characterised by thin, pigmented, keratinised, hairless epidermis covering subcutaneous, collagenous, and adipose tissue, which make up the pads. These pads act as a cushion for the load-bearing limbs of the animal. The paw consists of the large, heart-shaped metacarpal or palmar pad (forelimb) or metatarsal or plantar pad (rear limb), and generally four load-bearing digital pads, although there can be five or six toes in the case of domestic cats and bears (including giant panda). A carpal pad is also found on the forelimb which is used for additional traction when stopping or descending a slope in digitigrade species. Additional dewclaws can also be present.
