Hormones that the posterior pituitary secretes are synthesized in the:
Anterior pituitary.
Hypothalamus.
Thalamus.
Posterior pituitary.
The Correct Answer is B
Hormones that the posterior pituitary secretes are synthesized in the hypothalamus.
They are made by neurons in the hypothalamus and stored and released by the posterior lobe of the pituitary gland, a small organ at the base of the brain.
They regulate water balance, blood pressure, and uterine contraction in the body.
Choice A is wrong because the anterior pituitary synthesizes its own hormones, such as growth hormone, thyroid-stimulating hormone, and prolactin.
Choice C is wrong because the thalamus is not involved in hormone synthesis or secretion. It is a part of the brain that relays sensory and motor signals to the cerebral cortex.
Choice D is wrong because the posterior pituitary does not synthesize hormones. It only stores and releases hormones made by the hypothalamus.
