Question
Describe the relationship between the pituitary and hypothalamus.
Solution
The relationship between the pituitary gland and the hypothalamus is a crucial one in the human body's endocrine system. Here's a step-by-step description of their relationship:
-
Location: The hypothalamus is located in the brain, just above the pituitary gland. They are connected by a small stalk, the pituitary stalk, which allows them to communicate.
-
Communication: The hypothalamus sends signals to the pituitary gland. These signals can either stimulate or inhibit the release of hormones from the pituitary.
-
Hormone Release: The hypothalamus produces and releases certain hormones, known as releasing hormones, into the blood. These hormones travel to the pituitary gland and signal it to produce its own hormones.
-
Control of Body Functions: The hormones released by the pituitary gland then travel throughout the body, influencing various bodily functions such as growth, blood pressure, metabolism, and reproduction.
-
Feedback Mechanism: The hypothalamus also receives feedback from the levels of hormones in the blood. If the levels of a certain hormone are too high or too low, the hypothalamus will adjust its signals to the pituitary gland to correct the imbalance.
In summary, the hypothalamus and pituitary gland work together to regulate the body's hormone levels and maintain homeostasis.

As you know, the hypothalamus is thebasal part of diencephalon, forebrain(Figure 22.1) and it regulates a widespectrum of body functions. It containsseveral groups of neurosecretory cellscalled nuclei which produce hormones.These hormones regulate the synthesis and secretion of pituitaryhormones. However, the hormones produced by hypothalamus are oftwo types, the releasing hormones (which stimulate secretion of pituitaryhormones) and the inhibiting hormones (which inhibit secretions ofpituitary hormones). For example a hypothalamic hormone calledGonadotrophin releasing hormone (GnRH) stimulates the pituitarysynthesis and release of gonadotrophins. On the other hand, somatostatinfrom the hypothalamus inhibits the release of growth hormone from thepituitary. These hormones originating in the hypothalamic neurons, passthrough axons and are released from their nerve endings. These hormonesreach the pituitary gland through a portal circulatory system and regulatethe functions of the anterior pituitary. The posterior pituitary is underthe direct neural regulation of the hypothalamus (Figure 22.2)
