What is epithalamus?

The human brain consists of four main areas: brain stem, brain, diagnosis and brain. Diecephalon is located near the center of the brain and consists of a hypothalamus, thalamus and epithalamu. Of the three sections consisting of Diecephalon, epithalamus is dorsal or furthest backwards. In terms of function, epithalamus is responsible for connecting the lympic system with the rest of the brain and for the regulation of hormones secreted by the pineal gland. On the way of the spinal cord to the skull, the cord passes into the brain through Medulla Oblongata and ends at the bottom of the middle brain. Just above and a few centimeters forward, the pituitaryights on the horizontal axis through the eyes and ears. Outstanding through Medulla Oblongata and pituitary Jeepithalamus and its related components.

Structures

in epithalamu include habenula, stria medularis and pineal body or pineal gland. Scientists do not fully understand all the functions of different structures in the epithalamus, although some functions are fromŘejmé. For example, scientists know that the regulation of circadian rhythms is responsible for the pineal gland, located in the back of the epithalamus. Melatonin, the hormone responsible for drowsiness, is excreted in a pineal gland in both humans and mammals to cause normal sleep cycles.

known as the "third eye", the body also participates in other functions of the body. No larger than a single grain of rice, the production of melatonin small pineal gland also inhibits sexual development in humans and animals until adolescence. Emotions and some motor tracks are also affected, due to the close similarities between melatonin and serotonin.

In addition to the Pineal gland, Habenula, also known as habenular nuclei. Scientists believe that habenula is involved in the regulation of the intake of nutrients and water of the body. In addition, research shows that Habenula contains an afferent or sensory input, fibers connecting the stria medularis with other parts of the brain involved in the release of serotonin, dopamine and norepinephrine.

projected backwards towards the habenular core jE Strai Medularis Thalam. Few is known about the hate of medularis than it is a bundle of eperential or sensory output, nerve fibers structured to form a comb between Thalam and Epithalam. Some anatomical databases cite Medularis as part of thalamus, while others refer to them as part of epithalamus.
