Accessory Structures of the Skin: Hair and Hair Follicles01:16

Accessory Structures of the Skin: Hair and Hair Follicles

5.0K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Accessory Structures of the Skin: Hair Growth and Types

2.7K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Hypodermis01:02

Hypodermis

8.1K
The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...

Accessory Structures of the Skin: Sebaceous Glands

4.9K
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...

Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

4.3K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Hormonal Regulation01:33

Hormonal Regulation

36.5K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

    Summary
    This summary is machine-generated.

    Hirsutism, or excessive hair growth in women, often indicates an underlying endocrine disorder. Polycystic ovary syndrome is the most frequent cause, but serious conditions like tumors require exclusion.

    Area of Science:

    • Endocrinology
    • Gynecology

    Background:

    • Hirsutism is defined as excess terminal hair growth in women of reproductive age.
    • It affects 5-10% of women and can be the sole sign of an androgen disorder.

    Purpose of the Study:

    • To provide an overview of hirsutism in women.
    • To highlight the association between hirsutism and underlying endocrine disorders.

    Main Methods:

    • This is a review article.
    • Information was gathered from the Department of Gynecology and Obstetrics, General Faculty Hospital and 1st Faculty of Medicine of Charles University, Prague.

    Main Results:

    • Polycystic ovary syndrome (PCOS) is the most common cause of hirsutism.
    • Hirsutism presentation ranges from mild cosmetic concerns to significant psychological distress.

    Conclusions:

    • While PCOS is common, rapid progression necessitates excluding androgen-secreting tumors (ovarian, adrenal).
    • Treatment varies from reassurance and local therapy to more extensive interventions based on severity and cause.
