9–16 The aden/o/hypophysis is composed of glandular tissue that manufactures

and releases several hormones. The neur/o/hypophysis is composed of nerve fibers

and releases neurohormones that it receives from the hypothalamus. Thus, the

neur/o/hypophysis merely acts as a storage site until the hormones are released. As

such, it is not a true endocrine gland in the precise sense. Refer to Figure 9–2 for a

summary of hormones secreted by the pituitary gland and their target organs.
