Several hormones are synthesized in the hypothalamus and transported to the anterior pituitary gland. The mechanism of transportation from hypothalamus to anterior pituitary gland is through the
hepatic portal system
coronary circulatory system
hypophyseal portal system
hypothalamus-hypophysial tract
The Correct Answer is C
a) Hepatic portal system: This carries blood from the gastrointestinal tract to the liver, not the brain.
b) Coronary circulatory system: This system supplies the heart muscle, not involved in hormone transport from hypothalamus.
c) hypophyseal portal system: The hypophyseal portal system is a specialized vascular system that transports releasing and inhibiting hormones from the hypothalamus to the anterior pituitary.
d) Hypothalamus-hypophysial tract: This is a neural pathway used to transport ADH and oxytocin to the posterior pituitary, not the anterior.

Correct Answer is B
Explanation
a) Is the vascular connection between the anterior pituitary and the hypothalamus: This describes the hypophyseal portal system, not the tract.
b) Is the neural connection between the hypothalamus and the neurohypophysis (posterior pituitary): The hypothalamic-hypophyseal tract consists of axons that transport oxytocin and ADH from the hypothalamus to the posterior pituitary for storage and release.
c) Conducts aldosterone to the hypophysis: Aldosterone is produced by the adrenal cortex and is not transported by this tract.
d) Is the site of prolactin synthesis: Prolactin is synthesized in the anterior pituitary, not in the hypothalamic-hypophyseal tract.
Correct Answer is D
Explanation
a) Is the body's immediate response to a real or perceived threat to survival: This defines the fight-or-flight response.
b) Elevates heart and respiration rates and blood glucose level: These are physiological responses to increase energy and oxygen delivery.
c) Decreases urinary and digestive functions: These are temporarily suppressed to prioritize critical functions.
d) All of these are correct: This includes all the listed accurate physiological responses.
