Questions and Answers

Match the following glands with their primary hormone(s):

Adrenal Gland = Catecholamines, Cortisol Anterior Pituitary Gland = Growth hormone, Prolactin Ovaries = Estrogen Pancreas = Glucagon, Insulin Parathyroid Gland = Parathyroid hormone Posterior Pituitary Gland = Oxytocin Testis = Testosterone Thyroid Gland = Calcitonin, T3 & T4

Which hormone directly lowers blood glucose levels by facilitating glucose uptake into cells?

  • Glucagon
  • Epinephrine
  • Cortisol
  • Insulin (correct)

Parathyroid hormone increases plasma calcium levels.

Flashcards

Pancreas

A gland located behind the stomach that produces insulin and glucagon, regulating blood sugar levels.

Thyroid

A butterfly-shaped gland in the neck that produces hormones (T3 & T4, Calcitonin) regulating metabolism, growth, and calcium levels.

Pituitary Gland

The 'master gland' in the brain that controls other endocrine glands and produces hormones like growth hormone and prolactin.

Insulin

A hormone produced by the pancreas that lowers blood glucose levels by enabling cells to take up glucose.

Glucagon

A hormone produced by the pancreas that raises blood glucose levels by signaling the liver to release stored glucose.

Study Notes

Gland Locations on Diagram

  • A: Pituitary
  • B: Hypothalamus
  • C: Pineal
  • D: Thyroid
  • E: Parathyroid
  • F: Thymus
  • G: Adrenal
  • H: Pancreas
  • I: Ovaries
  • J: Testis

Hormone-Gland Matching

  • Calcitonin is produced by the Thyroid gland
  • Catecholamines are produced by the Adrenal gland
  • Cortisol is produced by the Adrenal gland
  • Estrogen is produced by the Ovaries
  • Glucagon is produced by the Pancreas
  • Growth hormone is produced by the Anterior Pituitary gland
  • Insulin is produced by the Pancreas
  • Oxytocin is produced by the Posterior Pituitary gland
  • Parathyroid hormone is produced by the Parathyroid gland
  • Prolactin is produced by the Anterior Pituitary gland
  • T3 & T4 produced by the Thyroid gland
  • Testosterone is produced by the Testis

Hormone Functions

  • Insulin lowers the blood glucose levels and regulates metabolism
  • Glucagon raises blood glucose levels
  • Oxytocin contracts the uterine muscle during labor
  • T3 & T4 controls metabolic rate and regulates growth and development
  • Calcitonin decreases plasma levels of calcium
  • Testosterone stimulates development of sperm and secondary male sex characteristics
  • Catecholamines stimulate the “fight, flight, or freeze” response
  • Growth hormone stimulates growth of bone and soft tissues.
  • Parathyroid hormone increases plasma levels of calcium
  • Cortisol is part of the stress response and regulates glucose, fat, and protein metabolism
  • Estrogen stimulates development of the ova and secondary female sex characteristics
  • Prolactin stimulates the breast to develop and produce milk
