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. Chaos reigns in his wake.]
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.
The inner ear contains the sensory organs for hearing and balance. The cochlea is the hearing part of the inner ear. The semicircular canals in the inner ear are part of our balance system.The cochlea is a bony structure shaped like a snail and filled with two fluids (endolymph and perilymph).The Organ of Corti is the sensory receptor inside the cochlea which holds the hair cells, the nerve receptors for hearing.The mechanical energy from movement of the middle ear bones pushes in a membrane (the oval window) in the cochlea. This force moves the cochlea's fluids that, in turn, stimulate tiny hair cells.he inner ear contains the sensory organs for hearing and balance. The cochlea is the hearing part of the inner ear.
