For most of us, it's difficult to imagine the complexity of our own human biology. In our day-to-day lives, we aren't conscious of the millions of cells working together in concert to let us do even the simplest tasks like eating, walking, or talking. And we're even less aware of what our body does that's beyond our direct volition.
This list celebrates just one of the many unsung heroic organs that make our body function, the hypothalamus. It's a tiny part of your brain that plays an enormous role in keeping the body running normally.

Interpreted Literally, the Word Means "Under Chamber"
The word "hypothalamus" is derived from the two Greek words "hypo" and "thalamus." Literally the word would mean something like "under chamber." Fitting, since the hypothalamus rests below the thalamus, between the two hemispheres of the brain.
To be a bit more specific, the hypothalamus lies near the center of the cranial cavity below the thalamus. Positioned along the front ends of the third ventricle, it is completely hidden by the overlaying cerebral hemisphere.
The hypothalamus itself is made of a group of nuclei contained in neural tissue. Each nuclei is responsible for specialized secretions that control certain aspects of the body. The nuclei are attached to neurons that transmit signals from the hypothalamus to the endocrine system.
No, it's not a dinosaur. The diencaphalon is a collection of structures housed under the cerebral cortex, including the thalamus and the hypothalamus. These structures play a vital part in relaying neural information and controlling visceral or subconscious bodily functions.
