Sebaceous Glands: Function, Development, Role In Pimples

Sebaceous gland, a small oil-producing gland present in the skin of mammals. Sebaceous glands are usually attached to hair follicles and release an oily substance, sebum, into the follicular duct and from there to the surface of the skin. Glands are distributed throughout the body with the exception of the palms and soles; there are most of them on the scalp and face.

The sebaceous gland secretes a mixture of fats (triglycerides, wax esters, squalene and cholesterol) and cellular debris, which are discharged as sebum through the sebaceous duct that connects the gland to the hair follicle. Sebum helps create a slightly oily surface film of the skin; thus helping to keep the skin flexible and preventing skin loss from excessive water absorption.

Sebaceous glands begin to form from embryonic hair follicles during the fourth month of gestation and are large and well developed at birth. They decrease during childhood, but increase again with the onset of puberty; glandular maturation appears to depend on circulating levels of male hormones, particularly testosterone.

Sebaceous glands are involved in the development of a common adolescent skin disorder known as acne vulgaris. Acne occurs when the exit from the gland to the surface of the skin is blocked, allowing sebum to accumulate in the follicle and sebaceous duct. The chemical breakdown of triglycerides in sebum, probably by bacteria, releases free fatty acids, which in turn trigger an inflammatory reaction that produces the typical acne lesions (pimples). The human body is a complex group of many different organs, systems, glands, bones and tissues. Weighing any one over the other does not do justice to a complex but orderly assemblage of this nature. Thus, studying each part of the body not only brings clarity but also helps us understand the key roles associated with each one.

So, let’s start with the definition of apocrine glands, a brief overview of the glands, and then dig deeper into what an apocrine gland is, what makes apocrine glands work, characteristics, structure, function, prevalence, and clinical significance.

Apocrine glands are a subtype of exocrine glands. They release their glandular apocrine secretion through the process of budding. After the glandular content is ready to be secreted, a bud is formed and it is at the end

Since part of the cell membrane is involved in the process of bud formation, it damages the cells a little. Unlike the other two ways of exocrine secretion, the secretion of apocrine glands not only has

Glands are a type of exocrine gland in which secretory products are released along with some parts of secreting cells, i.e. parts of the cell membrane that bud off from the cell. The secretory products of the apocrine gland are released from the cell through a part of the cell membrane that surrounds them and finally separates. Therefore, an apocrine gland differs from other exocrine glands (i.e. holocrine and merocrine glands) in that it includes some parts of the cell with secretory products. Examples of apocrine glands are mammary glands and axillary sweat glands.

In simple language, a gland is an organ responsible for the production, processing and release of biologically important substances in the complex human machinery. These biological substances or secretions are associated with very specific functions and roles within our system.

More specifically, there are two categories or types of glands in our body. The first category is endocrine glands, and the second is exocrine glands. Refer to the table below to find the characteristic differences between the two types of glands.

Within the exocrine glands, there are several ways of subcategorizing the large group. Exocrine glands can be divided based on three different criteria.

Just look at the tabular differences below so you can go from glands to exocrine glands to apocrine glands.

Apocrine glands are glands that damage cells more than merocrine glands, but are less damaging to cells than holocrine glands. They release their glandular secretions when the bud separates from the apocrine cell.

Before understanding the structure of the apocrine glands, we present to you the general structure of the exocrine glands as a whole.

Exocrine glands – regardless of whether they are merocrine, holocrine or apocrine – all these glands are mainly made of two components.

Apocrine gland histology can be observed under a light microscope using various staining techniques. Cells in the apocrine glands can be distinguished using histological staining techniques.

There are different places in our body where apocrine glands are present. They serve different purposes on all these pages.

Previously, mammary glands were considered modified apocrine glands. But studies have shown that these are only true apocrine glands.

Apocrine glands primarily develop during puberty and begin to secrete milky sweat. Among them, apocrine sweat glands commonly exhibit this age-related behavior. They are also called

Apocrine glands are not only present in humans. It is common knowledge that they also occur in animals. Some of the animals where their presence has been recorded are listed here along with some important functions.

Yes, you heard right. The apocrine glands in the axillary regions (armpits) in humans are known to possess steroidal, oily compounds, some of which are “pheromones”. These pheromones are released when you sweat under the influence of emotion.

These apocrine glands are sensitive to the adrenal glands. Therefore, when you are affected by emotions, these glands are activated and produce more pheromones. These smelly chemicals are not only used by human biology to attract another person, but are also released when you are affected by emotions of fear, anxiety, happiness, etc. This stench is associated with the apocrine gland…

75% of patients suffering from excessive sweating claim that it has negatively affected their social life, sense of emotional and mental well-being.

Hyperhidrosis is excessive sweating that has no necessary reasons for its occurrence such as heat or exercise. The condition can affect the whole body or specific areas. It is known to disrupt daily activities and can even cause psychological trauma.

Primary focal hyperhidrosis refers to excessive sweating in specific areas (therefore described as focal). No underlying medical conditions cause this type of sweating. The most common focal areas are hands, feet, underarms, face or head. In general, people
