This gland is known as the “master gland” because it controls many other endocrine glands.

What is the pituitary gland?

100

This hormone increases heart rate and prepares the body for “fight or flight.”

What is epinephrine (adrenaline)?

100

These are the male reproductive organs that produce sperm and testosterone.

What are the testes?

100

This condition is caused by insufficient insulin production or action

What is diabetes mellitus?

100

This system works closely with the endocrine system to maintain homeostasis using rapid signaling.

What is the nervous system?

200

These are chemical messengers released into the bloodstream by endocrine glands.

What are hormones?

200

This hormone regulates metabolism and is produced by the thyroid gland.

What is thyroxine (T4)?

200

This structure in the female reproductive system is the site of fertilization.

What is the fallopian tube (oviduct)?

200

This disorder results from an overactive thyroid gland.

What is hyperthyroidism?

200

This hormone pair works antagonistically to regulate blood calcium levels.

What are calcitonin and parathyroid hormone (PTH)?

300

This type of feedback mechanism reduces hormone production once a certain level is reached.

What is negative feedback? 

300

This hormone stimulates ovulation in females.

What is luteinizing hormone (LH)?

300

This hormone is primarily responsible for the development of male secondary sexual characteristics.

What is testosterone?

300

This condition is caused by a deficiency of iodine in the diet.

What is a goiter?

300

This stage of sperm development involves the transformation into a motile sperm cell.

What is spermiogenesis?

400

This hormone, produced by the pancreas, lowers blood glucose levels by promoting uptake into cells.

What is insulin?

400

This hormone promotes water reabsorption in the kidneys and is released from the posterior pituitary.

What is antidiuretic hormone (ADH)?

400

This phase of the menstrual cycle involves the thickening of the uterine lining.

What is the proliferative phase?

400

This syndrome is caused by prolonged exposure to high cortisol levels.

What is Cushing’s syndrome?

400

This hormone maintains the uterine lining during pregnancy and is produced after ovulation.

What is progesterone?

500

This hypothalamic-pituitary relationship involves hormones traveling through a specialized portal blood system.

What is the hypothalamic-pituitary portal system?

500

This hormone from the anterior pituitary stimulates the adrenal cortex to release cortisol.

What is adrenocorticotropic hormone (ACTH)?

500

This process ensures genetic variation by separating homologous chromosomes during gamete formation.

What is meiosis?

500

This condition involves underproduction of growth hormone during childhood, leading to short stature.

What is pituitary dwarfism?

500

This hormone produced by the placenta maintains pregnancy by supporting progesterone production early on.

What is human chorionic gonadotropin (hCG)?
