Types of Hormones02:13

Types of Hormones

83.4K
Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

Types of Hormones

Hormones are classified into four main groups: steroids, eicosanoids, amino acid-based derivatives, and peptide hormones.
Steroids and eicosanoids fall under the category of lipid-soluble hormones. Steroids are derived from cholesterol and feature four interconnected carbon rings with variable side chains. Notable examples include estradiol from ovaries and testosterone from testes, exemplifying the critical roles of these lipid-soluble hormones in reproductive physiology. Eicosanoids, derived...

Hormonal Regulation01:33

Hormonal Regulation

36.0K
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.

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Plant Hormones

27.5K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Pigmentation01:19

Pigmentation

4.2K
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...

Summary

Melasma development is linked to genetics and sun exposure, but hormonal factors like pregnancy and therapies also play a role. The precise link between hormone secretion and melasma remains complex and requires further investigation.

Area of Science:

  • Dermatology
  • Endocrinology

Background:

  • Melasma is a common skin condition influenced by genetic predisposition and sunlight.
  • Hormonal factors, including pregnancy, hormone therapies, and oral contraceptives, are frequently associated with melasma.
  • Limited laboratory studies exist on the correlation between hormonal alterations and melasma.

Purpose of the Study:

  • To review existing literature on hormonal variations in individuals with melasma.
  • To explore the complex relationship between hormone secretion and melasma development.
  • To present clinical cases illustrating the challenges in defining this association.

Main Methods:

  • Literature review of studies on hormone variations in men and women with melasma.
  • Analysis of clinical case reports.

Main Results:

  • Hormonal alterations are frequently reported in association with melasma.
  • Data on laboratory correlations between hormones and melasma are limited.
  • Clinical cases highlight the difficulty in definitively defining the hormone-melasma relationship.

Conclusions:

  • While hormonal factors are implicated in melasma, the precise biochemical and physiological links are not fully understood.
  • Further research, including robust laboratory analyses, is needed to clarify the role of hormone secretion in melasma pathogenesis.
  • The interplay between genetics, environment, and hormones in melasma requires continued investigation.
