1. Endocrine System Physiology

Key Concepts & Definitions

  • Hormones: Chemical messengers secreted by endocrine glands that regulate physiological processes such as metabolism, growth, reproduction, hydration, and stress response.
  • Negative Feedback Loop: A regulatory mechanism where an increase in a hormone's effect inhibits its own production, maintaining homeostasis.
  • Receptors: Specific protein structures on or inside target cells that bind hormones, initiating a cellular response.
  • Hydrosoluble Hormones: Water-soluble hormones (peptides, catecholamines) that bind to membrane receptors, causing rapid responses.
  • Liposoluble Hormones: Fat-soluble hormones (steroids, thyroid hormones) that cross cell membranes and influence gene transcription, leading to slower, sustained effects.
  • Pulsatile Secretion: Discontinuous, rhythmic hormone release that maintains receptor sensitivity and prevents desensitization.
