The hind limb and foot of the elephant are oriented semi-plantigrade, and closely resemble the structure and function of the human foot. The tarsals and metapodials are arranged so as to form an arch, similarly to the human foot. The six toes of each foot of the elephant are enclosed in a flexible sheath of skin.
Plantigrade foot occurs normally in humans in static postures of standing and sitting. It should also occur normally in gait (walking). Hypertonicity , spasticity , clonus , limited range of motion, abnormal flexion neural pattern, and a plantar flexor (calf) muscle contracture, as well as some forms of footwear such as high heeled shoes may ...
The brown rat (Rattus norvegicus), also known as the common rat, street rat, sewer rat, wharf rat, Hanover rat, Norway rat and Norwegian rat, is a widespread species of common rat. One of the largest muroids, it is a brown or grey rodent with a body length of up to 28 cm (11 in) long, and a tail slightly shorter than that. It weighs between 140 ...
A closeup of a rat tail. The characteristic long tail of most rodents is a feature that has been extensively studied in various rat species models, which suggest three primary functions of this structure: thermoregulation, [13] minor proprioception, and a nocifensive-mediated degloving response.

In terrestrial vertebrates, digitigrade (/ ˈ d ɪ dʒ ɪ t ɪ ˌ ɡ r eɪ d /) [1] locomotion is walking or running on the toes (from the Latin digitus, 'finger', and gradior, 'walk').A digitigrade animal is one that stands or walks with its toes (phalanges) on the ground, and the rest of its foot lifted.
True mice and rats do not contain this structure but their cheeks are elastic due to a high degree of musculature and innervation in the region. [11] Volume rendering of a mouse skull (CT) using shear warp algorithm. While the largest species, the capybara, can weigh as much as 66 kg (146 lb), most rodents weigh less than 100 g (3.5 oz).
Various aged naked mole-rats. The naked mole-rat (Heterocephalus glaber), also known as the sand puppy, [6] is a burrowing rodent native to the Horn of Africa and parts of Kenya, notably in Somali regions. [1] It is closely related to the blesmols and is the only species in the genus Heterocephalus. [7]
Pes of a rodent, Eurasian hamster Cricetus cricetus. The pes (Latin for foot) is the zoological term for the distal portion of the hind limb of tetrapod animals. [1] It is the part of the pentadactyl limb that includes the metatarsals and digits ().
