The integumentary system includes skin, hair, scales, feathers, hooves, claws, and nails. It has a variety of additional functions: it may serve to maintain water balance, protect the deeper tissues, excrete wastes, and regulate body temperature , and is the attachment site for sensory receptors which detect pain, sensation, pressure, and ...
Nails can also become thickened (onychogryphosis), loosened (onycholysis), infected with fungus (onychomycosis), or degenerate (onychodystrophy). A common nail disorder is an ingrowing toenail (onychocryptosis). DNA profiling is a technique employed by forensic scientists on hair, fingernails, toenails, etc.
In humans, some of the more common skin appendages are hairs (sensation, heat loss, filter for breathing, protection), arrector pilli (smooth muscles that pull hairs straight), sebaceous glands (secrete sebum onto hair follicle, which oils the hair), sweat glands (can secrete sweat with strong odour or with a faint odour (merocrine or eccrine ...
The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin.
Celebrity nail artist Julie Kandalec sent these graphic nails with brown detailing down the Christian Cowan runway. She used the CND Shellac line to give the look lots of shine and longevity.
The two main types of human skin are glabrous skin, the nonhairy skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [16] Within the latter type, hairs in structures called pilosebaceous units have a hair follicle , sebaceous gland , and associated arrector pili muscle. [ 17 ]
For nails, biotin may strengthens the keratin, plus CoQ10, which maximizes cellular energy to support the proteins that make up hair, skin and nails. Star Ingredient: CoQ10 Form: Capsule
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. [1] The major function of this system is as a barrier against the external environment. [ 2 ]
