Verified step by step guidance
1
Understand the role of the hypothalamus in the endocrine system. The hypothalamus is a crucial part of the brain that links the nervous system to the endocrine system via the pituitary gland.
Identify the types of hormones released by the hypothalamus. The hypothalamus primarily releases releasing and inhibiting hormones that regulate the secretion of hormones from the anterior pituitary gland.
Examine the list of hormones provided in the problem: Adrenocorticotropic hormone (ACTH), Thyrotropin-releasing hormone (TRH), Oxytocin, and Prolactin.
Recognize that Thyrotropin-releasing hormone (TRH) is a releasing hormone produced by the hypothalamus. It stimulates the release of thyroid-stimulating hormone (TSH) from the anterior pituitary gland.
Conclude that TRH is the hormone released by the hypothalamus, as it fits the category of releasing hormones that regulate pituitary function.
