What are faneras and what is their function for the organism?

Skin care is a frequent, influencing concern health beyond aesthetics. But many times people do not know or confuse the terms, and it is good to clarify, for example, What are fanerae and their function.

“The skin is the largest organ of the body. It and its derivatives (hair, nails, sweat and sebaceous glands) constitute the intergumentary system,” he defines Medline Plusthe United States National Library of Medicine.

And he adds that one of the main functions of the skin is to protect the body from external factors such as bacteria, chemicals and temperature.

In turn, it is known that the skin is made up of tissues of embryological origin and different tissue structures: the epidermis and the dermis (skin).

Although an article from the Faculty of Medicine of the Autonomous University of Mexico states that for some authors the epidermis (or subcutaneous layer) should also constitute this organ).

But beyond each part appear those who are considered skin appendages.

What are faneras

THE the phanerae are complementary and visible structures on the skin or that protrude from it, dermatologists define.

They are fans nails, hair and sweat glands in humans, as well as feathers, hooves, scales and horns in other animals.

In this way the phanera, together with the skin, constitute what is known as the integumentary system.

Seagrasses are composed of a high percentage of the protein called keratinthey explain in Wikipedia.

This substance, they add, is very rich in sulfur and constitutes the main component of the outermost layers of the epidermis of vertebrates and seagrasses, organs derived from the ectoderm.

What are the functions of faneras?

Together with the skin, hair, nails, sweat glands and sebaceous glands, the so-called fanerae or skin appendages, are part of the integumentary system.

This is why it is worth specifying its function in any case, which many do not take into account or underestimate.

HAIR OR HAIR. Composed of keratinized epithelial cells, human hair or body hair includes the hair shaft and a soft, thick bulb attached to the skin. The root ends in the hair bulb and this sits in a sac-shaped hole known as a follicle, from which the hair grows.

The key role of hair is to keep us warm. A large amount of heat is lost through the head.

As for nose hair, ear hair and eyelashes, It protects us from dust and other tiny particles.

NAIL. In addition to the aesthetic aspect, they protect hands and feet from possible external injuries and help to pick up small objects.

The formation process is similar to that of hair. The epidermal cells located under the root of the nail move towards the surface of the skin. Each cell becomes a thin plate and these are grouped together forming nails.

In children they are flexible and smooth, while in adults they are harder. Furthermore, over the years they lose their shine and become fragile.

SEBACEOUS GLANDS. They are associated with the hair follicles of the body. Just as hair does not grow on the palms of the hands and soles of the feet, they do not have sebaceous glands, they explain in the section Health From The world from Spain.

However, there are numerous and large ones present on the face and scalp. The sebum they produce causes our skin to have a kind of oil that protects it.

SWEAT GLANDS. They regulate body temperature. For example, if it is very hot, both apocrine and eccrine cells immediately produce sweat.

Apocrines usually appear in the puberty stage, when sexual hormones They experience a mismatch. While eccrines, moreover, usually respond to fear and nerves.
