Multiple Choice

Which two hormones are secreted by the posterior pituitary gland, and what are their primary functions?

Thyroid-stimulating hormone and adrenocorticotropic hormone; they regulate thyroid and adrenal gland function, respectively.

Oxytocin and vasopressin; they regulate uterine contractions and water balance, respectively.

Melatonin and insulin; they regulate sleep cycles and blood sugar levels, respectively.

Prolactin and growth hormone; they stimulate milk production and growth, respectively.

Verified step by step guidance

Identify the hormones secreted by the posterior pituitary gland. The posterior pituitary gland releases two main hormones: oxytocin and vasopressin (also known as antidiuretic hormone, ADH).

Understand the primary function of oxytocin. Oxytocin is primarily involved in stimulating uterine contractions during childbirth and also plays a role in lactation by promoting the ejection of milk from the mammary glands.

Understand the primary function of vasopressin (ADH). Vasopressin helps regulate water balance in the body by increasing water reabsorption in the kidneys, which reduces urine output and helps maintain blood pressure.

Differentiate between the posterior and anterior pituitary gland functions. The anterior pituitary gland secretes hormones like thyroid-stimulating hormone (TSH) and adrenocorticotropic hormone (ACTH), which are not secreted by the posterior pituitary.

Review the options provided in the problem. The correct answer is oxytocin and vasopressin, as they are the hormones secreted by the posterior pituitary gland and are responsible for regulating uterine contractions and water balance, respectively.
