Feb 24, 2023 · The hypothalamus–pituitary complex can be thought of as the “command center” of the endocrine system. This complex secretes several hormones that directly produce responses in target tissues, as well as hormones that regulate the synthesis and secretion of hormones of other glands.
In addition, the hypothalamus is anatomically and functionally related to the pituitary gland (or hypophysis), a bean-sized organ suspended from it by a stem called the infundibulum (or pituitary stalk). The pituitary gland is cradled within the sellaturcica of the sphenoid bone of the skull.
Oct 30, 2023 · The major functions of the hypothalamus include: control of the pituitary gland, regulation of body temperature, food intake, fluid intake, control of the autonomic nervous system, control of stress, emotional expression and aggression, sleep and waking, sexual arousal and memory.
Nov 3, 2023 · The pituitary gland is anatomically and functionally closely related to the hypothalamus . The pituitary gland is made of two active lobes; anterior and posterior. The anterior lobe of the pituitary gland, also known as the adenohypophysis, produces and secretes the majority of pituitary hormones.
How does the hypothalamus interact with the pituitary gland? Your pituitary gland sits just below your hypothalamus. It consists of two lobes, called the anterior pituitary and posterior pituitary. Your hypothalamus is connected to and communicates with your anterior lobe through a network of blood vessels.
In this chapter, we provide an overview of the historical landmarks, embryologic, gross, microscopic and functional anatomy of the mammalian and human hypothalamus and pituitary, and how the hypothalamus relates to the rest of the brain and responds to peripheral signals.
The pituitary gland (or hypophysis cerebri) is an endocrine gland in vertebrates. In humans, the pituitary gland is located at the base of the brain, protruding off the bottom of the hypothalamus. The human pituitary gland is oval shaped, about the size of a chickpea, [2] and weighs 0.5 grams (0.018 oz) on average.
