Verified step by step guidance1
Understand the role of the pituitary gland: The pituitary gland is divided into two main parts, the anterior lobe and the posterior lobe, each responsible for releasing different hormones.
Identify the hormones released by the posterior lobe: The posterior lobe of the pituitary gland releases two main hormones, oxytocin and vasopressin (also known as antidiuretic hormone, ADH).
Differentiate between anterior and posterior lobe hormones: The anterior lobe releases hormones such as Thyroid-Stimulating Hormone (TSH), Prolactin, and Growth Hormone, which are not released by the posterior lobe.
Recognize the function of oxytocin: Oxytocin is involved in several physiological processes, including uterine contractions during childbirth and milk ejection during breastfeeding.
Conclude that among the options provided, oxytocin is the hormone released by the posterior lobe of the pituitary gland.
