What is the Dermis? The dermis is comprised of two layers: the papillary dermis and the reticular dermis. The papillary dermis is the more superficial of the two, and lies just beneath the epidermal junction. It is relatively thin and is made up of loose connective tissue, which includes: Capillaries.

The dermis and protein fibres The dermis is made up of connective tissue: a gelatinous structure formed from connective fibres, which acts as a liaison and support system between the various tissues and cells.The dermis contains between 20 and 40% of the body's total water content and is between 10 and 40 times thicker than the epidermis.t is largely made up of: 1  Fibroblasts: the predominant cells in the dermis. 2  They synthesize the collagen, elastin and glycoprotein structural fibres. 3  The destruction of these fibres automatically occurs with age.

- Dermis. The dermis consists mostly of connective tissue and is much thicker than the epidermis. It is responsible for the skin's pliability and mechanical resistance and is also involved in the regulation of the body temperature.The dermis supplies the avascular epidermis with nutrients by means of its vascular network.he subcutaneous layer below the dermis consists of loose connective tissue and much fat. It acts as a protective cushion and helps to insulate the body by monitoring heat gain and heat loss. Not all authors consider this layer a part of the skin, but it definitely has a strong impact on the way the skin looks.

Dermis The dermis is tightly connected to the epidermis through a basement membrane. Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix. It also contains Mechanoreceptors that provide the sense of touch and thermoreceptors that provide the sense of heat.part from these cells, the dermis is also composed of matrix components such as collagen (which provides strength), elastin (which provides elasticity), and extrafibrillar matrix, an extracellular gel-like substance primarily composed of glycosaminoglycans (most notably hyaluronan), proteoglycans, and glycoproteins.

Which connective tissue composes the dermis of the skin? The dermis is the 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.

The Skin Layers of the epidermis: The epidermis is made up of 95% keratinocytes but also contains melanocytes, Langerhans cells, Merkel cells, and inflammatory cells. The stratum basale is primarily made up of basal keratinocyte cells, which can be considered the stem cells of the epidermis.

Structure, Functions and Problems of the Skin Epidermis. The epidermis is the relatively thin, tough, outer layer of the skin. Most of the cells in the epidermis are keratinocytes. They originate from cells in the deepest layer of the epidermis called the basal layer. New keratinocytes slowly migrate up toward the surface of the epidermis.he dermis, the skin's next layer, is a thick layer of fibrous and elastic tissue (made mostly of collagen, elastin, and fibrillin) that gives the skin its flexibility and strength. The dermis contains nerve endings, sweat glands and oil (sebaceous) glands, hair follicles, and blood vessels.

Some facts about skin The apical layers of the dermis are folded, to form dermal papillae, which are particularly prominent in thick skin. The hypodermis. This layer is underneath the dermis, and merges with it. It mainly contains adipose tissue and sweat glands. The adipose tissue has metabolic functions: it is resonsible for production of vitamin D, and triglycerides.

What is the Dermis? The dermis is the second, or middle, layer of a person's skin. It contains fibers of collagen and elastin, which are important proteins. The collagen and elastin in this layer of skin form a durable mesh-like layer.dditionally, the dermis contains sebaceous glands, hair follicles, sweat glands, and nerves. People cannot see the dermis because it is below the epidermis, the top layer of skin, and hidden from view.

Epidermis Layers of the Dermis The dermis is composed of two layers. The upper layer, called the stratum papillarosum (papillary layer), is in contact with the epidermis and accounts for about one-fifth of the entire dermis (see fig. 2.2) .Numerous projections, called papillae, extend from the upper portion of the dermis into the epidermis.. Stratum basale (basal layer).The stratum basale consists of a single layer of cells in contact with the dermis. Four types of cells compose the stratum basale: keratinocytes, melanocytes, tactile cells (Merkel cells), and nonpigmented granular dendrocytes (Langerhans cells).

Chapter 4: The skin, hair and nails The skin consists of two quite different layers: (1) the epidermis, a superficiallayer of stratified epithelium that develops from ectoderm, and (2) the dermis, or corium, an underlying layer of connective tissue that is largely mesodermal in origin. The dermis makes up the bulk of the skin.he follicle is dilated at its base to form the bulb (matrix). In the obtuse angle between the root of a hair and the surface of the skin, a bundle of smooth muscle fibers, known as an arrector pili muscle, is usually found. It extends from the deep part of the hair follicle to the papillary layer of the dermis.
