Common characteristics
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, bears and the 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.
The paw also includes a horny, beak shaped claw on each digit. Though usually hairless, certain animals do have fur on the soles of their paws. An example is the Red Panda, whose furry soles help insulate them in their snowy habitat.
Animals with paws
- Felines, such as cats and tigers; some of these animals may have toe tufts
- Members of the Canidae family, such as dogs and foxes
- Rabbits have paws with very sharp nails and have no pads underneath them.
- Bears and raccoons
- Weasels and other mustelids
- Rodents

- The role of parallel fibers (PFs) in cerebellar physiology remains controversial. Early studies inspired the "beam" hypothesis whereby granule cell (GC) activation results in PF-driven, postsynaptic excitation of beams of Purkinje cells (PCs). However, the "radial" hypothesis postulates that the asc

- Neuronal activity results in a local increase in blood flow. This concept serves as the basis for functional MRI. Still, this approach remains indirect and may fail in situations interfering with the neurovascular coupling mechanisms (drugs, anesthesia). Here we establish that water molecular diffus
