Highly keratinized processes that are sharp and curved, or flat with pointed margins. They are found especially at the end of the limbs in certain animals.
A group of lysosomal proteinases or endopeptidases found in aqueous extracts of a variety of animal tissues. They function optimally within an acidic pH range. The cathepsins occur as a variety of enzyme subtypes including SERINE PROTEASES; ASPARTIC PROTEINASES; and CYSTEINE PROTEASES.
The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago. (From Walker's Mammals of the World, 6th ed, p801)
'Elastin' is a highly elastic protein in connective tissue that allows many tissues in the body to resume their shape after stretching or contracting, such as the skin, lungs, and blood vessels.
A vine (Uncaria tomentosa) indigenous to the Amazon rainforest whose name is derived from its hook-like thorns. It contains oxindole alkaloids and glycosides and has many medicinal uses.

Anatomical and functional disorders affecting the foot.
Bones that make up the SKELETON of the TOES, consisting of two for the great toe, and three for each of the other toes.
A condition characterized by a series of interrelated digital symptoms and joint changes of the lesser digits and METATARSOPHALANGEAL JOINTS of the FOOT. The syndrome can include some or all of the following conditions: hammer toe, claw toe, mallet toe, overlapping fifth toe, curly toe, EXOSTOSIS; HYPEROSTOSIS; interdigital heloma, or contracted toe.
The outer covering of the body composed of the SKIN and the skin appendages, which are the HAIR, the NAILS; and the SEBACEOUS GLANDS and the SWEAT GLANDS and their ducts.
An infraorder of chiefly marine, largely carnivorous CRUSTACEA, in the order DECAPODA, including the genera Cancer, Uca, and Callinectes.
Organs and other anatomical structures of non-human vertebrate and invertebrate animals.
General name for two extinct orders of reptiles from the Mesozoic era: Saurischia and Ornithischia.
The species Panthera tigris, a large feline inhabiting Asia. Several subspecies exist including the Siberian tiger and Sumatran tiger.
The farthest or outermost projections of the body, such as the HAND and FOOT.
Distortion or disfigurement of the foot, or a part of the foot, acquired through disease or injury after birth.
'Housing, Animal' refers to the physical structure or environment designed and constructed to provide shelter, protection, and specific living conditions for various domestic or captive animals, meeting their biological and behavioral needs while ensuring their welfare and well-being.
An infraorder of New World monkeys, comprised of the families AOTIDAE; ATELIDAE; CEBIDAE; and PITHECIIDAE. They are found exclusively in the Americas.

The comparative study of animal structure with regard to homologous organs or parts. (Stedman, 25th ed)
The surface of a structure upon which one stands or walks.
Keratins that form into a beta-pleated sheet structure. They are principle constituents of the corneous material of the carapace and plastron of turtles, the epidermis of snakes and the feathers of birds.
Steroids that bring about MOLTING or ecdysis in insects. Ecdysteroids include the endogenous insect hormones (ECDYSONE and ECDYSTERONE) and the insect-molting hormones found in plants, the phytoecdysteroids. Phytoecdysteroids are natural insecticides.
The largest order of CRUSTACEA, comprising over 10,000 species. They are characterized by three pairs of thoracic appendages modified as maxillipeds, and five pairs of thoracic legs. The order includes the familiar shrimps, crayfish (ASTACOIDEA), true crabs (BRACHYURA), and lobsters (NEPHROPIDAE and PALINURIDAE), among others.
OPPORTUNISTIC INFECTIONS with the soil fungus FUSARIUM. Typically the infection is limited to the nail plate (ONYCHOMYCOSIS). The infection can however become systemic especially in an IMMUNOCOMPROMISED HOST (e.g., NEUTROPENIA) and results in cutaneous and subcutaneous lesions, fever, KERATITIS, and pulmonary infections.
