Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

2.0K
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Major Hormones and Their Functions

2.3K
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...

Hormonal Control of the Ovarian Cycle

7.3K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle.  At puberty, GnRH secretion increases in both frequency and...

Hormonal Regulation

36.6K
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.

Hypodermis01:02

Hypodermis

8.3K
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...

Summary
This summary is machine-generated.

Hirsutism, excessive male-pattern hair growth, affects both sexes. Diagnosis and management involve identifying underlying causes like polycystic ovary syndrome and endocrine disorders, with various pharmacotherapy and surgical options available.

Area of Science:

  • Endocrinology
  • Dermatology

Background:

  • Hirsutism is characterized by excessive terminal hair growth in a male pattern on androgen-dependent areas of the body.
  • It affects both men and women and has numerous potential underlying causes.

Purpose of the Study:

  • To provide a comprehensive overview of hirsutism, including its definition, common etiologies, diagnostic approaches, and management strategies.
  • To highlight the importance of evaluating for underlying endocrinopathies in all affected individuals.

Main Methods:

  • Review of common and rare causes of hirsutism.
  • Discussion of diagnostic guidelines and evaluation of endocrine disorders.
  • Overview of pharmacotherapy and surgical treatment options.

Main Results:

  • Common causes include polycystic ovary syndrome, idiopathic hyperandrogenemia, and adrenal hyperplasia.
  • Less common causes include androgen-secreting tumors, Cushing syndrome, and thyroid dysfunction.
  • Management strategies focus on addressing the underlying cause and may involve medications or surgery.

Conclusions:

  • Hirsutism requires a thorough diagnostic evaluation to identify the underlying cause, which can range from common endocrine disorders to rare tumors.
  • Management is tailored to the specific etiology and may include pharmacotherapy (e.g., hormonal agents, antiandrogens) or surgical intervention for tumors.
