A nurse is describing the endocrine system to a nursing student. Which statement best describes the negative feedback system of the pituitary gland?
a. The pituitary gland produces five hormones that are interdependent.
b. Target organs stimulate the hypothalamus, which in turn produces hormones.
c. The anterior pituitary stimulates the produc-tion of posterior pituitary hormones.
d. The pituitary gland secretes hormones that stimulate target organs to produce specific hormones. As hormonal secretions of the target organs increase, the pituitary gland decreases the secretion of the stimulating hormone.
D
The pituitary stimulates target organs to produce specific hormones. When enough hormone is produced, the target organ signals the pituitary to stop secretion of the stimulating hormone. There are six hormones secreted by the anterior pituitary; they are not interdependent. The anterior pituitary gland stimulates target organs to produce specific hormones and does not control production of posterior pituitary hormones.
