Eläimenkarvaa

Eläimenkarvaa, commonly referred to as animal hair or fur, encompasses the various types of filamentous epidermal outgrowths that cover the bodies of mammals. This covering serves multiple biological functions, including insulation against temperature fluctuations, protection from physical damage and UV radiation, and in some species, camouflage. The texture, length, and density of eläimenkarvaa vary greatly among different species and even within breeds of the same species, adapting to the animal's habitat and lifestyle.

The composition of eläimenkarvaa is primarily keratin, a tough, fibrous protein also found in human hair, nails, and skin. Each hair strand grows from a follicle embedded in the dermis. The color of eläimenkarvaa is determined by melanin pigments. The shedding and regrowth cycle of eläimenkarvaa, known as molting, is influenced by seasonal changes, hormonal fluctuations, and the animal's life stage.

In a human context, eläimenkarvaa has several applications. It is historically and currently used in the textile industry for products like wool from sheep, cashmere from goats, and angora from rabbits. These fibers are valued for their warmth, softness, and durability. However, eläimenkarvaa can also be a common allergen for humans, triggering allergic reactions in susceptible individuals. Additionally, its presence in the environment can be a nuisance, requiring regular cleaning in homes where pets reside. The study of eläimenkarvaa is part of zoology and also has relevance in fields like forensics, where hair analysis can aid in identification.
