Accessory Structures of the Skin: Hair Growth and Types01:20

Accessory Structures of the Skin: Hair Growth and Types

1.5K
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...

Accessory Structures of the Skin: Hair and Hair Follicles

2.4K
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...

Adrenal Gland Disorders01:27

Adrenal Gland Disorders

1.6K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

3.7K
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...

Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

60.4K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Hormones of the Adrenal Glands01:31

Hormones of the Adrenal Glands

2.6K
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

    Area of Science:

    • Psychology
    • Public Health
    • Endocrinology

    Background:

    • Chronic physiological stress research using hair cortisol is expanding in general populations.
    • Research on physiological stress in homeless youth is limited, despite their elevated risk for adverse outcomes.
    • Homeless youth face higher risks for mental health issues, suicide, and overdose.

    Purpose of the Study:

    • To assess the feasibility of collecting hair samples for cortisol measurement in diverse homeless youth.
    • To understand participation variations in hair cortisol research among homeless youth.
    • To explore sociodemographic factors influencing participation in stress research.

    Main Methods:

    • Analysis of survey and hair collection data from three pilot studies involving homeless youth.
    • Collection of sociodemographic data (age, race, ethnicity, sex, sexual orientation).
    • Examination of participation rates and reasons for nonparticipation in hair sampling.

    Main Results:

    • High overall participation (88.4%) in hair sampling for cortisol measurement.
    • Insufficient hair length was the primary reason for nonparticipation.
    • Black, multiracial, and male youth showed higher nonparticipation rates.

    Conclusions:

    • Hair cortisol collection is a feasible method for studying chronic stress in homeless youth.
    • Integrating physiological stress measures is recommended for this high-risk population.
    • Further research should address methodological considerations and explore stress in homeless youth.
