C) Regulating hunger
What are neurohormones?
Neurohormones are hormones released by neurons in the hypothalamus that influence the function of other endocrine glands.
True or False: The hypothalamus directly produces and releases hormones into the bloodstream.
False
What is the role of the arcuate nucleus in the hypothalamus?
It is involved in the regulation of appetite and energy balance.
Fill in the blank: The hypothalamus regulates the release of _______ from the adrenal glands.
cortisol
What is the relationship between the hypothalamus and the pituitary gland?
The hypothalamus controls the pituitary gland by releasing hormones that stimulate or inhibit its hormone production.
