Verified step by step guidance
1
Understand the anatomy of the pituitary gland, which is divided into two parts: the anterior pituitary and the posterior pituitary.
Recall that the anterior pituitary synthesizes and secretes its own hormones, such as Thyroid-stimulating hormone (TSH), Adrenocorticotropic hormone (ACTH), and Prolactin (PRL).
Recognize that the posterior pituitary does not produce hormones itself but stores and releases hormones produced by the hypothalamus.
Identify the two main hormones released by the posterior pituitary: Oxytocin and Antidiuretic hormone (ADH, also called vasopressin).
Conclude that among the options given, Oxytocin is the hormone released from the posterior pituitary gland.
