Identify the hormone with its correct matching of source and function.
Identify the hormone with its correct matching of source and function.
The correct option is A Melatonin - pineal gland, regulates the normal rhythm of the sleep-wake cycle
The correct option is A.
Explanation of the correct option:
The pineal gland produces the hormone melatonin. It functions as a biological clock, regulating the normal rhythm of the sleep-wake cycle known as the circadian cycle.
Explanation of the incorrect option:
Option B:
The posterior pituitary secretes the hormone oxytocin. Because it ejects milk from mammary glands during suckling, oxytocin is also known as milk ejection hormone. It's also known as birth hormone because it produces labour pain and uterine contractions in preparation for the baby's birth.
Option C:
The hormone atrial natriuretic factor dilates blood arteries and lowers blood pressure. The release of atrial natriuretic hormone is stimulated by increased blood flow to the heart atria.
Option D:
The corpus luteum secretes the hormone progesterone. It is known as a pregnancy hormone because it regulates the changes that occur during pregnancy. It's a steroid hormone.
Final answer: The pineal gland produces the hormone melatonin. It functions as a biological clock, regulating the normal rhythm of the sleep-wake cycle known as the circadian cycle.
