- The dermis is the inner layer of the skin, and includes: hair follicles, nerves, sweat glands, small blood vessels and sebaceous glands. It is made up of connective tissue and consists of two layers, the stratum papillare (upper layer) and the stratum reticulare.he dermis acts as a supporting structure for the epidermis and contains proteins such as collagen and elastin. These provide the skin with strength, the ability to stretch and the ability to return to its original shape.

- The skin consists of an outer layer of epiblastic origin, the epidermis, and an inner layer of mesoblastic origin, the dermis. Derma, or dermis, is the true skin lying under the epidermis (cuticle), which is known in contrast as the scarf-skin.

The Skin Key Points. 1  The dermis is divided into a papillary region and a reticular region. 2  The primary function of the dermis is to cushion the body from stress and strain, and to also provide: elasticity to the skin, a sense of touch, and heat. 3  The dermis contains hair roots, sebaceous glands, sweat glands, nerves, and blood vessels.

- Below the epidermis is the next layer of our skin, the dermis, which is made up of blood vessels, nerve endings, and connective tissue. The dermis nourishes the epidermis. Without certain molecules in the dermis, our skin wouldn't stretch when we bend or reposition itself when we straighten up.

- 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.

- FIGURE 1. Skin is composed of 3 main layers. The dermis is directly below the epidermis and gives skin its strength. and support. Unlike the epidermis, the dermis contains nerves, blood. vessels and fibroblasts that provide the sensory receptors, deliver. nutrients, and maintain the structural foundation of the skin.

INTEGUMENTARY SYSTEM The dermis is composed of two layers: (1) the papillary dermis closest to the epithelium, is composed of less dense connective tissue and is vascularized with capillary networks penetrating the papillae and (2) the underlying reticular dermis composed of avascular, dense irregular connective tissue (Dermis).

Functions of the Integumentary System The epidermis does not contain blood vessels. The deeper layers of the epidermis get their nutrients by diffusion from blood vessels in the dermis. 2 people found this useful. Edit. Share to: 1  The Five Major Parts of the Brain At its most basic, the brain controls the body. 2  Electrical impulses are sent along the nervous system to and from the brain that regulate all movement.

- The dermis is the deeper skin layer consisting of two layers: the papillary and elastic, both containing collagen. Blood vessels (capillaries) and nerves are found in this layer. The principle structural component of the dermis is the protein collagen, produced by fibroblasts dispersed throughout the dermis.kin thickness varies and is on average 1mm thick; the thinnest on eyelids at 0.5mm and the thickest at 1.5mm on the palms and soles. Skin consists of multiple layers (stratified), epidermis, dermis and hypodermis (deepest layer).

What layer of skin that contains the blood vessels and nerves closet to the surface of of the skin is? It contains no blood vessels or nerves. Blood nourishes this layer by diffusion. The middle layer of the skin, the layer that is asked about in this question is called the 'dermis' and conatins blood vessels, nerves and other structures.The lower layer of the skin is called the 'sub-cutis' and contains fat.he layer of the skin tht contains blood vessels and nerves closest to the surface of the skin is the __ layer.

What Is the Function of the Dermis? Structures found in the dermis include: 1  Connective tissue - Specifically collagen and elastin. 2  Blood capillaries (the smallest of blood vessels) and other small vessels. 3  Lymph vessels. 4  Sweat glands.

- The inner layer of the two main layers of the skin. The dermis has connective tissue, blood vessels, oil and sweat glands, nerves, hair follicles, and other structures. It is made up of a thin upper layer called the papillary dermis, and a thick lower layer called the reticular dermis. Epidermis.

Human Physiology/Print Version The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

Skin Anatomy and Physiology In other words, elastin provides the skin with its elasticity. Both collagen and elastin proteins are produced in specialized cells called fibroblasts, located mostly in the upper edge of the dermis bordering the epidermis. Intertwined throughout the dermis are blood vessels, lymph vessels, nerves, and mast cells.

- 3. Dermis, This inner (deeper) layer is a vascular connective tissue of mesodermal origin. It can be further divided into a superficial papillary layer and a deeper reticular layer. The papillary layer contains extensive capillary networks, which nourish the epidermis.

Human skin The epidermis contains no blood vessels, and cells in the deepest layers are nourished almost exclusively by diffused oxygen from the surrounding air and to a far lesser degree by blood capillaries extending to the upper layers of the dermis.he dermis is the layer of skin beneath the epidermis that consists of epithelial 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.

Dermis The dermis is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that consists of connective tissue and cushions the body from stress and strain.n addition, hair follicles, sweat glands, sebaceous glands, apocrine glands, lymphatic vessels and blood vessels are present in the dermis. Those blood vessels provide nourishment and waste removal for both dermal and epidermal cells.

What is the Papillary Dermis? The papillary dermis contains blood vessels that serve two primary functions. One of these functions is to provide the tissue of the skin with vital nutrients and oxygen.d. The second function of the blood vessels within the papillary dermis to to regulate body temperature. Nerves present in the skin tell the body what the surrounding temperature is. This information can be used to either conserve or dissipate heat by increasing or decreasing blood flow to the dermis.

- Made up of 80% water, elastin fibres and collagen floating in a glycoprotein gel, the dermis is the tissue supporting the skin. In contrast with the epidermis, it is vascularised, enabling it to not only provide energy and nutrition to the epidermis but also to play a primordial role in thermoregulation and in healing.erves skin deep. Nerves include free nerve endings, that penetrate the epidermis a little or are linked to nervous corpuscles including the Meissner, Pacini and Ruffini corpuscles, which generate sensations coming from the skin-touch, temperature, or pressure.

The Skin 1 The primary function of the dermis is to cushion the body from stress and strain, provide elasticity to the skin, and a sense of touch, and heat. 2  The dermis also contains hair roots, sebaceous glands, sweat glands, nerves, and blood vessels.  The hypodermis lies below the dermis and contains a protective layer of fat.

- Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
