Regulation of _ is NOT a function of hypothalamus in humans.
Correct answer: D. Circadian rhythms
- A. Body temperature
- B. Maintaining Blood water potential
- C. Maintaining urine osmolarity
- D. Circadian rhythms
Explanation
The hypothalamus is the control centre for the regulation of blood water potential and urine osmolarity, mainly via the hormone ADH (antidiuretic hormone) and using the pituitary gland and collecting duct of the kidneys as the effector. The hypothalamus is the control centre for the regulation of body temperature. It is regulated by the thermoregulatory centre within the hypothalamus, which coordinates information to produce changes like vasoconstriction or vasodilation of arterioles supplying blood to the skin, controlling the production of sweat, and stimulating the secretion of hormones like adrenaline and thyroxine. Hypothalamus, however, does not regulate Circadian rhythms & emotions as circadian rhythm is regulated by the pineal gland, which produces melatonin, and emotions are regulated by the amygdala.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
