12 parts of the Human skin and their functions


parts function human skin

Pores

These are small, almost imperceptible pores that permit the skin to remain tight, firm, and youthful. When you desire to shrink your pores both in size and number, serums feel fresh and hydrating. The use of hydroxy acid exfoliators such as Exfol Serum or LacSal Serum helps to ensure that your pores are kept clear.

Hair shaft

The hair shaft is the part of the hair that sticks out of the skin. The hair shaft is connected to the follicle. There are a lot of components that make up hair structure to make it the fastest growing tissue in the body. Hair can be found on many parts of the body including head.

Skin surface

The whole surface of the skin is potholed by the orifices of sweat glands and hair follicle pores also known as and is furrowed by intersecting lines that delineate characteristic patterns. All individuals have roughly similar markings on any one part of the body, but the details are unique. The lines are slanting in the general direction of elastic tension.

Sweat pore

This is a simple tubular gland of the skin that secretes sweat, in humans it is broadly in nearly all parts of the skin, and is mainly made up of an epithelial tube extending spirally from a minute pore on the surface of the skin into the dermis or subcutaneous tissues where it ends in a convoluted tuft known as alsosudoriferous gland, sudoriparous gland

Nerve ending

The structure in which the distal end of the axon of a nerve fiber ends is also known as nerve end. The end of a nerve, at the distal end of an axon; nerve endings are the millions of points on the surface of your body and inside it which send messages to your brain when you feel sensations such as heat, cold, and pain.

Sebaceous gland

The Sebaceous gland is the small oil-producing gland located in the skin of mammals. Sebaceous glands are normally attached to hair follicles and release a fatty substance known as sebum, into the follicular duct and from there to the surface of the skin. The glands are distributed all over the body with the exception of the palms of the hands and the soles of the feet.

Connective tissue

Connective tissue is group of tissues in the body that maintains the form of the body and its organs and provides cohesion and internal support. The connective tissues include a lot of types of fibrous tissue that differ only in their density and cellularity in addition to more specialized and recognizable variants—bones, ligaments, tendons, cartilage, and adipose tissue.

Adipose tissue

Adipose tissue, or fat, is an anatomical word for loose connective tissue made up of adipocytes.Its major role is to store energy in the form of fat, although it as well cushions and insulates the body. Obesity in animals, including humans, is not dependent on the amount of body weight, but on the amount of body fat – particularly adipose tissue.

Arteriole

Arteriole is a small branch of an artery that leads to a capillary. The oxygenated hemoglobin known as the (oxyhemoglobin) makes the blood in arterioles (and arteries) look bright red. The greatest change in blood pressure and velocity of blood flow takes place at the transition of arterioles to capillaries.

Venule

As the capillaries converge, small venules are created whose role is to collect blood from the capillary beds (i.e., the networks of capillaries). The venules are made up of an endothelial tube supported by a small amount of collagenous tissue and, in the larger venules, by a few smooth muscle fibres as well.

Sweat gland

Sweat glands are coiled tubes of epidermal origin, though they are located in the dermis. Their secretory cells surround a central space, or lumen, into which the secretion is extruded. There are two different types: eccrine glands open by a duct directly onto the skin surface; apocrine glands normally develop in association with hair follicles and open into them.

Capillaries

Capillaries are the smallest of the blood vessels and serve as the link between the arterial and venal systems of the cardiac system. The action of the diaphragm and muscles in the arms and legs exerts a massaging effect that assists to move blood back to the heart to exchange oxygen and other nutrients for waste products.
