Chen, the 18-year-old who became U.S. champion with a score 40 points higher than the rest of the competition, was a no-doubt choice. With a five-quad program that is pushing the sport to literal new heights, Chen is the best American hope for a singles figure skating medal. âItâs been a dream of mine to be selected on the U.S. Olympic team as long as I can remember,â Chen said. âThe Olympics have really motivated me, ever since I started skating as a little kid.â [Nathan Chen secures first at U.S. nationals.

Cortical neurons are the cells of the brain's largest region, the two hemispheres of the cerebral cortex. Most of the complex activity of the brain enabling thought, perception, and voluntary movement is connected to the activity of these neurons.
Pineal Gland. The pineal gland, also called pineal body or epiphysis cerebri, is a small cone-shaped structure that extends posteriorly from the third ventricle of the brain. The pineal gland consists of portions of neurons, neuroglial cells, and specialized secretory cells called pinealocytes.ituitary Gland. The pituitary gland or hypophysis is a small gland about 1 centimeter in diameter or the size of a pea. It is nearly surrounded by bone as it rests in the sella turcica, a depression in the sphenoid bone. The gland is connected to the hypothalamus of the brain by a slender stalk called the infundibulum.
