This gland helps control metabolism.
What is the thyroid gland?
This hormone stimulates secretion of thyroid hormone from the thyroid gland.
What is thyroid-stimulating hormone (TSH)?
This is the “master gland” that controls other endocrine glands.
What is the pituitary gland?
This brain region acts as the command center for the endocrine system.
What is the hypothalamus?
The endocrine system regulates body functions through these chemical messengers.
What are hormones?
These are the male and female reproductive glands.
What are the gonads (testes and ovaries)?
This hormone helps the body conserve water during urine formation.
What is vasopressin (antidiuretic hormone)?
The anterior pituitary releases hormones in response to signals from this brain region.
What is the hypothalamus?
These travel through the hypothalamic-hypophysial portal system to reach the pituitary gland.
What are releasing and inhibiting hormones?
The hypothalamus communicates with the pituitary gland using both of these methods.
What are hormones and nerve signals?
This gland helps regulate metabolism, the immune system, and stress response.
What is the adrenal gland?
This hormone stimulates uterine contraction and milk ejection during breastfeeding.
What is oxytocin?
The posterior pituitary releases these two hormones.
What are vasopressin and oxytocin?
This hypothalamic hormone triggers ovulation in females.
What is gonadotropin-releasing hormone (GnRH)?
This organ releases IGF to promote growth when stimulated by growth hormone.
What is the liver?
This gland aids in development of lymphocytes for the immune system.
What is the thymus?
These hormones, produced by the gonads, control sexual characteristics.
What are testosterone and estrogen?
This pituitary hormone promotes milk production in females.
What is prolactin (PRL)?
This hypothalamic hormone leads to the release of ACTH from the pituitary.
What is corticotropin-releasing hormone (CRH)?
This gland’s hormones help the body respond to stress.
What are the adrenal glands?
This gland regulates blood sugar levels by releasing insulin and glucagon.
What is the pancreas?
This hormone stimulates overall body growth and is influenced by GHRH.
What is growth hormone (GH)?
This pituitary hormone stimulates the secretion of cortisol from the adrenal cortex.
What is adrenocorticotropic hormone (ACTH)?
This hormone from the hypothalamus initiates growth hormone release.
What is growth hormone–releasing hormone (GHRH)?
Together, the hypothalamus and pituitary form this important feedback system.
What is the hypothalamic-pituitary axis?
