Why hypothalamus is called Master of 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. The system maintains its own balance.

How do you test for hypothalamus?
- Hormone injections followed by timed blood samples.
- MRI or CT scans of the brain.
- Visual field eye exam (if there is a tumor)
What color is the hypothalamus?
Dark green: pars tuberalis; light blue : nervous tissue in the hypothalamus; light green: pars distalis or anterior pituitary gland (adenohypophyseal tissue); red: blood vessels of hypophyseal portal vessels bringing releasing hormones from the neurosecretory terminals in the median eminence to stimulate or inhibit ...
What is the first gland the hypothalamus triggers?
