Identify the role of the pituitary gland in the endocrine system. It is known as the 'master gland' because it secretes hormones that regulate other endocrine glands.
Understand the structure of the pituitary gland. It is divided into two lobes: the anterior lobe (adenohypophysis) and the posterior lobe (neurohypophysis).
Locate the pituitary gland anatomically. It is situated at the base of the brain, within a bony structure called the sella turcica.
Review the hormones produced by the pituitary gland. The anterior lobe produces hormones like growth hormone, ACTH, TSH, LH, FSH, and prolactin, while the posterior lobe releases oxytocin and vasopressin (ADH).
Clarify the production of insulin. Insulin is not produced by the pituitary gland; it is produced by the beta cells of the pancreas. Therefore, the statement that the pituitary gland directly produces insulin is false.
