Which of the following hormones are secreted by the adrenal gland?

The adrenal gland is responsible for producing a variety of hormones that play critical roles in the body's response to stress, regulation of metabolism, and maintaining homeostasis. Among the hormones secreted by the adrenal gland, mineralocorticoids are specifically produced in the zona glomerulosa of the adrenal cortex. The primary mineralocorticoid is aldosterone, which regulates sodium and potassium balance and thus affects blood pressure.

The other listed hormones are not secreted by the adrenal gland. Growth hormone is produced by the anterior pituitary gland and is involved in growth and metabolism regulation. Prolactin, also produced by the anterior pituitary, primarily regulates lactation. Oxytocin is produced by the hypothalamus and released by the posterior pituitary; it plays roles in childbirth and milk release during breastfeeding. Therefore, among the given options, mineralocorticoids are the only hormones secreted directly by the adrenal gland.
