The convex shape may be evidence that the base of each structure was tubular in life, anchoring like other integumentary structures such as Mammalian hair or Avian feathers into a follicle.

The "'integumentary system "'comprises skin, and the appendages of skin, such as hair, nails, sweat glands, sebaceous glands, and sensory nerves.

Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states ( like, in certain circumstances, melanonychia and racquet nails ).

There are several conditions of or affecting the human integumentary system that are associated with an increased risk of developing nonmelanoma skin cancer ( i . e . squamous cell carcinoma and basal cell carcinoma ).

The majority of dinosaurs known to have had feathers or protofeathers are saurischians, however featherlike " filamentous integumentary structures " are also known from the ornithischians " Tianyulong " and " Psittacosaurus ".

It is known from a type fossil specimen; slab and counterslab ( PIN 2548 / 4 and PIN 2584 / 5 ), and five referred specimens of possible integumentary appendages ( PIN 2584 / 7 through 9 ).

The skin, which is part of the integumentary system, plays an important role in the somatic nervous system because it contains a range of nerve endings that react to heat and cold, touch, pressure, vibration, and tissue injury.

Many conditions affect the human integumentary system the organ system covering the entire surface of the In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm that forms the dermis and subcutaneous tissues.

A look at his publications reveals his ability to use novel approaches in diverse areas of reproductive biology ( e . g ., embryology, placentation, and fetal membranes ), ecological physiology, hibernation, and the integumentary, urinary, and digestive systems.

I am not thusly offended because there is no rational reason to object to particular organs or biological systems which are normal, healthy parts of human physiology; I am no more offended by clitorises or testicles than I am by the integumentary system or kidneys or adrenal glands.
