Lecture: Organs and Glands that Release Hormones

Overview

• Focus on organs and glands that release hormones
• Brief coverage of key hormones
• Subsequent videos: detailed discussion on each hormone
• Important for nursing students to understand endocrine disorders
• Covered on cards 2-4

Hypothalamus

• Located in the brain
• Releases 4 key hormones:
  • Corticotropin-releasing hormone (CRH)
  • Thyroid-releasing hormone (TRH)
  • Growth hormone-releasing hormone (GHRH)
  • Gonadotropin-releasing hormone (GnRH)
• Mnemonic: Cutthroat Good Game (C, T, G, G)

Pituitary Gland

• Located in the brain
• Anterior Pituitary Gland:
  • Thyroid-stimulating hormone (TSH)
  • Prolactin
  • Follicle-stimulating hormone (FSH)
  • Luteinizing hormone (LH)
  • Adrenocorticotropic hormone (ACTH)
  • Growth hormone (GH)
  • Mnemonic: TP FLAG (T, P, F, L, A, G)
• Posterior Pituitary Gland:
  • Anti-diuretic hormone (ADH)
  • Oxytocin

Thyroid Gland

• Located in the neck
• Produces:
  • T3 (Triiodothyronine)
  • T4 (Thyroxine)
  • Calcitonin

Parathyroid Glands

• 4 glands near the thyroid gland
• Produces Parathyroid hormone (PTH)

Adrenal Glands

• Located on top of the kidneys
• Adrenal Cortex (outer layer):
  • Aldosterone
  • Cortisol
  • Androgens
• Adrenal Medulla (inner layer):
  • Epinephrine
  • Norepinephrine

Pancreas

• Located behind the stomach
• Produces:
  • Insulin
  • Glucagon

Testes

• Produces Testosterone

Ovaries

• Produces:
  • Estrogen
  • Progesterone
