The epidermis is the top layer of the skin and consists mainly of keratin. The hypodermis is the deepest layer and contains blood vessels, nerves, fat and connective tissue.

Healthcare professionals use short needles and hold them at 45 degrees against the skin to give subcutaneous injections. They may gently pinch the skin to separate the skin from the underlying muscle.

Adipocytes: Key Players In Metabolic Homeostasis

A layer of fat under the skin stores energy and absorbs shock from physical injuries to protect internal organs. It also aids in body thermoregulation as it provides an insulating layer.

The subcutaneous area is under the skin and below the dermis layer. It forms the base of the upper layers and unites them with the bones and bones below. The subcutaneous area consists of subcutaneous fat and connective tissue.

With an average surface area of ​​2 square meters, the skin is the largest organ in the human body. It consists of three different layers, the deepest of which is called the hypodermis. The answer to what hypodermis is: hypo is latin for under and dermis is skin. As the deepest layer, the hypodermis is often defined as the base of the human skin and is mainly composed of connective tissue and adipose tissue. Connective tissues are made of collagen proteins and elastin and are important in supporting the upper layers of the hypodermis. Adipose is a layer of fat that is important for several functions of the hypodermis.

The hypodermis layer is often called the subcutaneous layer, Greek for lower layer. Finally, hypodermis in Latin means subcutaneous in Greek. This means that the subcutaneous layer has the same definition as the hypodermis and the two terms are used interchangeably. Subcutaneous fat actually refers to the adipose tissue in the subcutaneous layer.

Visceral Fat And Myocardial Infarction In Copd

There are places on Earth that are very cold and sometimes very wintery. Somehow we can survive those conditions. This is mainly due to the fat layer under the top two layers of the skin. The skin consists of an outer layer or epidermis, a middle layer or dermis, and an inner fat layer or subcutaneous tissue layer. The fat in the subcutaneous tissue layer is called adipose tissue, a tissue made up of fat cells.

What Is The Function Of Subcutaneous Adipose Tissue

As noted, the skin of vertebrates, including humans, consists of three layers. He defined the dermis as the lowest layer, or base, of the hypodermis. The middle layer is simply called the dermis and it provides the elasticity and stability of the skin due to its fibrous elastin structures and collagen. The upper layer, the epidermis, is called the epi, Latin for above, and controls the loss of water from the body and acts as a physical barrier against pathogens due to its keratin structures. Although considered the deepest layer, the hypodermis is not technically part of the skin and is often considered the layer of tissue that supports and connects the skin (ie, the dermis and epidermis) to the underlying bones and muscles.

The types of tissues in the hypodermis can provide insight into its basic functions. It is known that the subcutaneous layer of the skin is mainly composed of connective and adipose tissues. Connective tissue is composed of collagen proteins and elastin and is vascularized. As for adipose tissue, it must be distinguished because it is present in internal organs and in the hypodermis. In internal organs, it is technically called visceral adipose tissue (see VAT) and in the skin, subcutaneous adipose tissue (SAT). As a result, the adipose tissue in the hypodermis is SAT; mainly composed of adipocytes (fat cells), which act as connective tissue and fat storage. SAT cells combine to form lobules separated by connective tissue, and it is these cells that make up the highest percentage of body fat in humans.

A number of conditions can occur in the hypodermis layer as a result of natural or external factors.

Obesity and some signs of aging are two common conditions related to the hypodermis. The subcutaneous layer does not have the same thickness throughout the body. Men are naturally thickest in the abdomen and thighs, while for women, the hypodermis is thicker in the groin, thighs, and fists. Excess fat is stored here, among others, as subcutaneous adipose tissue, and the obesity epidemic has made this layer an important research area in recent years.

When it comes to aging, as a person gets older, the subcutaneous adipose layer naturally thins. This impairs the insulating function of the thin hypodermis, so older people often feel cold. It also means there is less underlying tissue to support the skin and maintain its elasticity and firmness. This is the main reason why the skin begins to sag and heal in certain areas, such as the face and neck, as people age.

A serious skin burn can damage the skin layer. In general, burns are classified according to the layer of skin affected:

Ulcers are open sores where the tissue breaks down. They are caused by blood flow that prevents the wound from healing properly, leading to scarring and ulceration. The lesions occur on the lower parts of the body, most commonly on the legs, hips, and back. In severe cases, the wound in the hypodermis can damage the subcutaneous tissue.

A pimple is a collection of pus that often causes the skin to become red and swollen. The skin tissues, as a result of the skin tissue’s defense reaction against foreign particles, especially bacteria, form an abscess capsule and increase blood flow to the area, causing redness and swelling. This is done to isolate the infection and to attract white blood cells. If located in the hypodermis, this condition is often called a subcutaneous abscess that requires drainage.

Soft tissue tumors are usually benign and usually arise in the subcutaneous tissue. These tumors are usually large and can be surgically removed if necessary.

Adipose Tissue: Diverse And Distinct Roles In Metabolic Health

Depending on the type of medication being given, injections can mainly target the skin layer. This is because although the subcutaneous layer does have blood vessels, they are few in number compared to most other tissues. Thus, when injecting into this layer, absorption of drugs will be a slow and steady process, making subcutaneous injections ideal for administering drugs such as insulin and epinephrine. The rate of absorption of drugs in this layer is slower than intracellular injections, but faster than intracellular (drug targeting). The most common sites for subcutaneous injections are the thighs, upper arms, and the front of the abdomen (under or at the level of the belly button). Healthcare professionals use short needles and hold them at 45 degrees against the skin to give subcutaneous injections. They may gently pinch the skin to separate the skin from the underlying muscle.

The skin is the largest organ in the human body and consists of three layers: the outermost layer is the epidermis, the middle layer is the dermis, and the deepest layer is the hypodermis. Hypodermis literally means skin in Latin and is also known as subcutaneous layer because subcutaneous has the same meaning in Greek. The hypodermis is often defined as the lowest layer of skin that connects and supports the underlying muscles and bones. The subcutaneous layer consists of connective tissue containing elastin and collagen, as well as a layer of fat (adipose), technically known as subcutaneous adipose tissue (SAT).

The hypodermis contains blood vessels and nerves that provide nourishment and sensation to the layers above. Subcutaneous fat stores energy, provides insulation for the body’s thermal regulation, and absorbs shock from physical injury to protect internal organs. Excess fat is stored in the SAT, making this layer the focus of obesity research. As people age, the layer of subcutaneous fat becomes thinner, leading to sagging and sagging skin that occurs with natural aging. If the burn involves damage to the hypodermis, it is considered a third-degree burn. The wounds can damage the subcutaneous tissue, and abscesses and tumors can form in this layer. Since the hypodermis contains a small amount of blood vessels, this layer is a target for injections, as drug absorption will be superior. Such injections are called subcutaneous injections and are used to administer several drugs,
