Understand the anatomy of the pituitary gland, which has two main parts: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis). Each part secretes different hormones.
Recall that the anterior pituitary produces and secretes several key hormones, including Thyroid-stimulating hormone (TSH), Growth hormone (GH), Adrenocorticotropic hormone (ACTH), Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), and Prolactin.
Recognize that Melatonin is secreted by the pineal gland, not the pituitary gland.
Know that Antidiuretic hormone (ADH) and Oxytocin are synthesized in the hypothalamus but stored and released by the posterior pituitary, not the anterior pituitary.
Therefore, identify Thyroid-stimulating hormone (TSH) as the hormone secreted by the anterior pituitary, distinguishing it from the other hormones listed.
