The hypothalamus region lies inferior and anterior to the thalamus. It connects to the pituitary gland by the stalk-like infundibulum. The pituitary gland consists of an anterior and posterior lobe, with each lobe secreting different hormones in response to signals from the hypothalamus.
What is the connection between the hypothalamus and pituitary gland?
The hypothalamus links the nervous and endocrine systems by way of the pituitary gland. Its function is to secrete releasing hormones and inhibiting hormones that stimulate or inhibit (like their names imply) production of hormones in the anterior pituitary.
Is the pituitary gland attached to the hypothalamus?
Anatomy of the pituitary gland
The gland is attached to the hypothalamus (a part of the brain that affects the pituitary gland) by nerve fibers and blood vessels. The pituitary gland itself consists of 2 major structures: Anterior lobe.
How does hypothalamus affect pituitary?
The hypothalamus produces separate hormones that stimulate or inhibit hormone production in the anterior pituitary. Hormones from the hypothalamus reach the anterior pituitary via the hypophyseal portal system. The anterior pituitary produces seven hormones.
Where is the hypothalamus located in relation to the pituitary gland?
The hypothalamus is located on the undersurface of the brain. It lies just below the thalamus and above the pituitary gland, to which it is attached by a stalk. It is an extremely complex part of the brain containing many regions with highly specialised functions.
Why hypothalamus is called master gland?
It’s called the master gland because it regulates the activity of the glands. The hypothalamus sends either hormonal or electrical messages to the pituitary gland. In turn, it releases hormones that carry signals to other glands.
How does the hypothalamus affect the circulatory system?
The hypothalamus plays a significant role in the endocrine system. It is responsible for maintaining your body’s internal balance, which is known as homeostasis. To do this, the hypothalamus helps stimulate or inhibit many of your body’s key processes, including: Heart rate and blood pressure.

How does the hypothalamus regulate the release of anterior pituitary hormones by?
Unlike the posterior pituitary which basically stores hormones produced by the hypothalamus, the hypothalamus regulates the anterior pituitary via secreting “releasing hormones,” somatostatin and dopamine.
How do you control the hypothalamus gland?
