Our skin is a complex engineered covering. The skin has a slightly acidic coating of oil at the surface. This coating protects the skin against some bacteria. Below the surface is a complex of sweat and oil glands, hair follicles, blood vessels, nerves, and muscle tissue. These are held together by a tough connective tissue called collagen. Collagen is very important in determining the health of the skin. The relative health of the collagen determines the contour of the skin, how wrinkled and lined it is. Healthy collagen is often called soluble collagen, because it can absorb and hold moisture. The skin has three layers. The inner most layer is known as the lower dermis, the middle layer is called the dermis, and the outer layer is known as the epidermis. The various glands such as the oil and sweat glands originate in the lower dermis. From here, they rise to the surface of the skin to eliminate waste matter. Lower dermis also acts as a cushion for the rest of the skin. It contains the finely distributed muscles of the skin which regulate body temperature. The dermis is the layer that lies underneath the epidermis, and it is composed entirely of living cells. It consists of bundles of tough fibers which give your skin its elasticity, firmness and strength. There are also blood vessels, which feed vital nutrients to these areas. The most important function of dermis is respiration. The countless tiny blood vessels, or capillaries end here in finely-drawn networks, from where they feed the outer skin layer. Dermis also determines the tone of the skin. This is the top layer of skin and the one you can actually see. It protects your body from invasion and infection and helps to seal in moisture. It's built up of several layers of living cells which are then topped by sheets of dead cells. It's constantly growing, with new cells being produced at its base. They quickly die, and are pushed up to the surface by the arrival of new ones, These dead cells eventually flake away, which means that every new layer of skin is another chance to have a soft, glowing complexion. The lower levels of living cells are fed by the blood supply from underneath, whereas the upper dead cells only need water to ensure they're kept plump and smooth. The epidermis is responsible for your coloring, as it holds the skin's pigment. It ranges in thickness from l/20-th of an inch on the palms and soles, to 1/200-th of an inch on the face. The skin contains the following specialized organs: Sebaceous glands are tiny organs which usually open into hair follicles on the surface of your skin. They produce an oily secretion, called sebum, which is your skin's natural lubricant. The sebaceous glands are most concentrated on the scalp and face - particularly around the nose, cheeks, chin and forehead, which is why these are usually the most oily areas of your skin. Sweat glands are all over your body. There are millions of them and their main function is to regulate your body temperature. When sweat evaporates on the skin's surface, the temperature of your skin drops. Hairs grow from the hair follicles. They can help keep your body warm by trapping air underneath them. There are no hairs on the soles of your feet and palms of your hands.

What is the name of the area just beneath the skin layer?
The area just beneath the skin layer is called the subcutaneous tissue, or subcutis. It is mainly composed of fat and connective tissue, providing insulation and cushioning for the body.
What are the layers of the skin in order?
The skin is composed of three main layers: the epidermis (outermost layer), the dermis (middle layer), and the hypodermis (innermost layer). The epidermis is responsible for protecting the body and regulating water loss, while the dermis contains blood vessels, nerves, and glands. The hypodermis is made up of fat and connective tissue that provides insulation and cushioning.
What is the function of subcutaneous fat in the human body?
Subcutaneous fat serves as a layer of insulation, providing warmth and protection for the body's organs. It also acts as a reserve of energy and helps regulate body temperature.
What layers made up the skin?
The skin is made up of three primary layers: the epidermis, the dermis, and the hypodermis (subcutaneous tissue). The epidermis is the outermost layer that provides a barrier to protect against environmental factors, the dermis contains connective tissue, sweat glands, and hair follicles, and the hypodermis stores fat and provides insulation.
Do humans have fatty layer under their skins?
Yes, humans have a layer of fatty tissue called subcutaneous fat located beneath the skin. This layer of fat serves various functions such as providing insulation, energy storage, and protection for organs.
Which tissue that stores fat in our body?
Adipose (fat) tissue. Fat can also be deposited in muscle; with a disease such as muscular dystrophy or on organs like the liver with liver damage. There is a type of fat (brown) which exists on or around internal organs, and subcutaneous fat which is underneath the the out layers of skin.
The subcutaneous layer is also called the hypodermis or the?
fatty tissue or subcutaneous fat
Is subcutaneous adipose tissue located under the dermis or the epidermis?
Subcutaneous fat is the bottom layer
In the skin the fat layer is also called?
In the skin, the fat layer is called the subcutaneous tissue or adipose tissue.
What are main layers of skin and which one contains fat cells?
The epidermis - it is the outer layer of skin and it contains 5 layers. From bottom to top the layers are:stratum basalestratum spinosumstratum granulosumstratum licidumstratum corneumThe dermis which contains two layers:The upper, papillary layerThe lower, reticular layerThe hypodermis or subcutaneous tissueThe fat cells are found in the adipose tissue which may develop anywhere, like around internal organs and in the bone marrow but tends to accumulate beneath the skin.
What are the structure and function of the subcutaneous layer?
The human skin is made up of three basic layers ; the epidermis (outer layer), the dermis(middle layer) beneath the epidermis and the subcutaneous layer beneath the dermis. The subcutaneous layers are fat cells and connective tissue that carry the blood vessels and nerves. It is located below the epidermis and the dermis, in that order, and is the third and final layer and consists primarily of loose connective tissue and lobules of fat.
What is the deepest and the most active division of skin?
The subcutaneous tissue (fat)
What is the deepest most active division of the skin?
The subcutaneous tissue (fat)
Describe the structure and function of the subcutaneous layer?
Subcutaneous TissueThe subcutaneous tissue is a layer of fat and connective tissue that houses larger blood vessels and nerves. This layer is important is the regulation of temperature of the skin itself and the body. The size of this layer varies throughout the body and from person to person.
Which if more dangerous Visceral fat or subcutaneous fat?
Subcutaneous fat is adipose tissue that lies superficial and close to the skin whereas visceral fat is adipose tissue that lies around the central organs (the viscera). Generally, visceral fat is considered a lot more harmful to health than subcutaneous fat as it affects the viscera and causes conditions such as diabetes mellitus and also heart disease.
What are the different layers and structures visible in a skin cross-section?
In a skin cross-section, the different layers and structures visible include the epidermis (outermost layer), dermis (middle layer), and subcutaneous tissue (innermost layer). The epidermis contains layers of cells, including the outermost layer of dead skin cells. The dermis contains blood vessels, nerves, hair follicles, and sweat glands. The subcutaneous tissue is made up of fat cells and connective tissue.
What type of tissue is located in the subcutaneous layer?
The subcutaneous tissue is the loose, connective tissue directly beneath the dermis. It is composed of adipose tissue or fat that is made up of lipocytes. These cells contain stored fat as an energy reserve. It also provides a layer of insulation to conserve internal body heat as well as a cushion to protect the bones and internal organs.
