Summary Hormones & Homeostasis

A snapshot of the summary - Hormones & Homeostasis

• intro

• What are the most important principles in endocrinology?

  • Hormone secretion
  • Hormone action
  • Principlesof feedback control
• Which kind of membrane receptors do you have?

  • G-protein-coupled
  • Ionotropic receptors
  • steroid receptors
  • Kinase-linked receptors
• How is the endocrine system evaluated?

  By measuring hormone concentrations
• How are endocrine disorders amendable to effective treatment?

  • deficiencies are treated with physiological hormone replacements
  • excessive conditions like benign/malignent glandular adenomas (cancer)
• What is the modern definition of an hormone?

  • productions does not necessarily take place in glands (gut)
  • other signals come from nearby cells (paracrine) or the own self (autocrine) of are from nutrition
  • many hormone receptors are not considered as endocrine targets
  • The classic production in glands, secretion in the bloodflow and binding on targets does still apply for some hormones
• Which two types of hormones are there?

  1. Growth factors
  2. Sex steroids which leads to epiphysial closure
• What are the most important hormones in the regulation of the homeostasis?

  1. TH
  2. Cortisol
  3. PTH (regulates Ca2+ and F2)
  4. Vasopressin
  5. Mineralocortoids
  6. insulin
• What are the main functions of hormones?

  • Growth and differentiation
  • Maintainance of the Homeostasis
  • Reproduction
• Which hormone is most important during child rearing?

  Oxytocin
• What is the field of endocrinology concerned with?

  • biosynthesis
  • storage
  • chemistry
  • physiological function
  • the productive cells and tissues
