Which hormone is secreted by the neurohypophysis?

The neurohypophysis, also known as the posterior pituitary gland, is responsible for the storage and release of hormones produced by the hypothalamus. One of the key hormones secreted by the neurohypophysis is oxytocin. This hormone plays several critical roles in the body, including stimulating uterine contractions during childbirth and promoting the milk ejection reflex during breastfeeding.

In contrast, cortisol is a steroid hormone released from the adrenal cortex, insulin is a peptide hormone produced by the pancreas that regulates glucose metabolism, and follicle-stimulating hormone (FSH) is secreted by the anterior pituitary and is involved in reproductive processes. Each of these hormones is associated with different endocrine glands and functions, making oxytocin the correct choice for this question about the neurohypophysis.
