Identify the hormone with its correct matching of source and function.
Options
- AOxytocin - posterior pituitary, growth and maintenance of mammary glands.
- BMelatonin - pineal gland, regulates the normal rhythm of sleepwake cycle.
- CProgesterone - corpus-luteum, stimulation of growth and activities of female secondary sex organs.
- DAtrial natriuretic factor-ventricular wall increases the blood pressure.
Correct answer
B. Melatonin - pineal gland, regulates the normal rhythm of sleepwake cycle.
Step-by-step solution
Oxytocin is produced by the posterior pituitary that helps in the process of parturition. Melatonin is secreted by the pineal gland and regulates the normal rhythm of sleep-wake cycle. Progesterone is the hormone secreted by the corpus-luteum that aids in maintenance of pregnancy. Atrial natriuretic factor is a polypeptide hormone secreted by the heart atria in response to atrial stretch and decreases the blood pressure.
