Accessory Structures of the Skin: Sebaceous Glands01:21

Accessory Structures of the Skin: Sebaceous Glands

3.2K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Major Hormones and Their Functions

1.1K
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Signs of Puberty

853
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Pigmentation01:19

Pigmentation

3.7K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Exocrine Glands: Methods of Secretion

5.5K
Exocrine glands are those that release their secretions through ducts. Based on their mode of secretion, they can be classified into merocrine, apocrine, and holocrine.
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine...

Skin Diseases and Disorders

4.6K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Summary

Increased sebum secretion impacts acne development, particularly in the U-zone. Factors like age and sex influence this relationship, explaining varied acne lesion distribution.

Area of Science:

  • Dermatology
  • Cutaneous Biology
  • Acne Pathogenesis

Background:

  • Sebum secretion is vital for acne development.
  • Acne lesion distribution does not always mirror sebum secretion patterns.
  • Understanding the interplay between sebum and acne distribution is crucial.

Purpose of the Study:

  • To investigate the effect of sebum secretion on acne development and distribution.
  • To identify other factors influencing the acne-sebum relationship.
  • To analyze sebum levels in different facial zones relative to acne prevalence.

Main Methods:

  • Retrospective study of 67 acne patients and 50 controls.
  • Categorization of acne patients into T-zone dominant, U-zone dominant, and mixed groups based on lesion distribution.
  • Comparison of sebum levels between acne patients and controls across facial zones, with correlation analysis between sebum and lesion count.

Main Results:

  • The U-zone dominant group exhibited higher sebum levels in the U-zone and overall compared to controls.
  • A significant correlation between sebum levels and lesion count was observed in the U-zone, but not the T-zone.
  • The U-zone showed a stronger acne-sebum relationship in male and younger patients.

Conclusions:

  • Elevated sebum secretion is linked to acne development, especially in the U-zone.
  • Age and sex are identified as influencing factors in the acne-sebum relationship.
  • Varied acne lesion distribution arises from the multifactorial influence of sebum secretion on individual patients.
