Endocrine System

• 3 zones of the Adrenal Cortex

  • Outer Zone
  • Middle Zone
  • Inner Zone
• Produces epinephrine (adrenalin) and norepinephrine

  Adrenal Medulla
• Hyposecretion of Glucocorticoids

  Addison's Disease
• Hypersecretion of Glucocorticoids

  Cushing's Syndrome
• Hypersecretion of Mineralcoticoids

  Aldosteronism
• Adrenal Androgens

  Virilism, Gynecomastia
• Inner portion of adrenal glands

  Adrenal Medulla
• Hypersecretion of epinephrine/some norepinephrine

  Prolonged fight or flight response
• Flattened organ in curve of duodenum

  Pancreas
• Alpha Cells

  Glucagon
• Beta Cells

  Insulin
• Acts on hepatocytes

  Glucagon
• Hyposecretion of Insulin

  Diabetes Mellitus
• Hypersecretion of Insulin

  Hyperinsulinism
• Hypersecretion of Glucagon


  Hyperglycemia
• Hyposecretion of Testosterone

  Sterility
• Hyposecretion of Estrogens, Progesterone


  Sterility
• Small gland attached to roof of third ventricle of brain

  Pineal Gland
• Sets body’s biological clock

  Pineal Gland
• The pineal gland is pine-cone-shaped and only about 1 cm in diameter.
• SAD is a depressive disorder that some individuals experience during the winter months when sunlight is minimal.
• Hormones [Steroids]

  (SCATE-PAD)

  
  

  Cortisol

  Aldosterone

  Testosterone

  Estrogen

  Progesterone

  Activated Vitamin D
• Hormones[Polypeptides]

  (Purely Protein)

  Oxytocin

  Prolactin
• Hormones [Amines]

  (AmEN T3T4)

  Epinephrine

  Norepinephrine

  T3

  T4
• Hormones [Glycoprotein]

  (Leah Trashes HEr FSH)

  LH

  TSH

  HCG

  Erythropoietin

  FSH
• T3 goes down, T4 goes down, TSH goes up

  Hypothyroidism
• T3 goes up, T4 goes up TSH goes down

  Hyperthyroidism
• Hormonal Disorders

  Primary: Thyroid

  Secondary: Pituitary Gland
• Chemical signals that is released through the bloodstream by their glands to stimulate target tissues

  Hormones
• 2 parts of the Pituitary Gland

  Anterior and Posterior
• Glands of the Endocrine System

  
  

  Hypothalamus

  Pituitary Gland

  Thyroid Gland

  Adrenal Glandand

  Testis

  Ovaries

  Mammary Gland
• Synthesizes Aldosterone

  Zona Glumerulosa
• Sugar Control

  Zona Fasiculata
• Synthesis of small amounts of sex hormones

  Zona Reticularis
• SaH: Glumerulosa

  Sweet: Fasiculata

  Sex: Reticularis
• Target Tissue of ACTH

  Adrenalcortex
• Mastergland

  Pituitary Gland
• The primary stimulus of the Hypothalamus

  Deep Slumber
• Oxytocin synthesizes the Hypothalamus but not directly stimulates the Pituitary Gland
• Storage and Release

  Posterior Pituitary Gland
