What is the dermis in the human skin and what are its functions?

It's the bit that helps you when you look up this in a proper biology book, say, in the library.

What is the dermis in the human skin and what are its functions?
The dremis is the sensitive vascular portion of the skin just underneath the epidermis.
Reply:the dermis is inner layers of skin lying beneath the epidermis. it's composed of collagen fibres interlaced with elastic fibres.


structures in it are: blood vessels, supplying sweat glands and hair follicles. Lymph vessels, forming a network throughout the dermis and deeper layers of epidermis. Nerve endings, which are sensitive to touch, change in temperature pressure and pain.
Reply:The dermis is a layer of skin beneath the epidermis that consists of connective tissue and cushions the body from stress and strain. The dermis is tightly connected to the epidermis by a basement membrane. It also harbors many nerve endings that provide the sense of touch and heat. It contains the hair follicles, sweat glands, sebaceous glands, apocrine glands and blood vessels. The blood vessels in the dermis provide nourishment and waste removal to its own cells as well as the Stratum basale of the epidermis.





The dermis is structurally divided into two areas: a superficial area adjacent to the epidermis, called the papillary region, and a deep thicker area known as the reticular region.





The papillary region is composed of loose areolar connective tissue. It is named for its fingerlike projections called papillae, that extend toward the epidermis. The papillae provide the dermis with a "bumpy" surface that interdigitates with the epidermis, strengthening the connection between the two layers of skin.





In the palms, fingers, soles, and toes, the influence of the papillae projecting into the epidermis forms contours in the skin's surface. These are called friction ridges, because they help the hand or foot to grasp by increasing friction. Friction ridges occur in patterns (see fingerprint) that are genetically determined and are therefore unique to the individual, making it possible to use fingerprints or footprints as a means of identification.





The reticular region lies deep in the papillary region and is usually much thicker. It is composed of dense irregular connective tissue, and receives its name from the dense concentration of collagenous, elastic, and reticular fibers that weave throughout it. These protein fibers give the dermis its properties of strength, extensibility, and elasticity.





Located within the reticular region are also the hair roots, sebaceous glands, sweat glands, receptors, nails, and blood vessels.





Tattoo ink is injected into the dermis. Stretch marks are also located in the dermis.
Reply:It is the second layer of the skin (from outside). It houses lots of nerve cells that help you to sense touch, pain, temperature and the like. It also contains glands that produce secretions in case of increased heat content of the body....





but you better read about your own assignment than posting a question on yahoo.... this site is mainly for things that you won't find in textbooks

Reply:skin is totally called dermis it has epidermis mesodermis %26amp; endodermis
