low concentration of thyroid hormones

As two different hormones reach the same cell they counteract the effect of one another. This outcome is known as a(n) ________

antagonistic effect

Estrogen

is released by the ovaries

[Pancreas] IS secondary endocrine function-kidney, thymus, intestines

pineal gland

[is located just above the cerebellum and releases the hormone melatonin. ?The hypothalamus sits superior to the pituitary gland.

Which hormone is NOT matched with its function?
