Identify a true statement about the pituitary gland. Multiple Choice The pituitary gland produces oxytocin and vasopressin. The posterior lobe of the pituitary synthesizes hormones. The posterior lobe of the pituitary gland is an extension of the nerve tissue of the hypothalamus. The hypothalamus produces the hormones that are stored in the anterior lobe of the pituitary gland.

Indicate whether the following statements about the pituitary glands are TRUE or FALSE. If the statement is false, correct the statement to make it true 1. The anterior and posterior pituitary glands are responsible for producing and releasing hormones. 2. The posterior pituitary gland is regulated by the hypothalamus via a positive feedback loop. 3. The hypothalamus regulates the release of cortisol via the sympathetic nervous system and that of epinephrine via the parasympathetic nervous system. 4. The releasing hormones from the hypothalamus stimulate the production of stimulating hormones and human growth hormone.
