Those interested in becoming financial advisors will make the decision to either go independent by establishing an investment advisory firm of their own, or to pursue employment as investment adviser representatives (IARs) with an existing investment advisory firm.
How hearing works. When these sound waves reach the ear, they travel down the ear canal and hit the eardrum, making it vibrate. Three tiny bones in the middle ear link the vibrating eardrum to a tiny bone structure in the inner ear called the cochlea. The cochlea is filled with liquid that carries the vibrations to thousands of tiny hair cells. The movement in the fluid causes the cells to carry a message to the nerve that is connected to the brain, which turns the signals into what you hear.
The Brain. Once a pain signal reaches the brain, a number of things can happen. Certain parts of the brain stem (which connects the brain to the spinal cord) can inhibit or muffle incoming pain signals by the production of endorphins, which are morphine-like substances that occur naturally in the human body.ain messages may also be directed along a variety of pathways in the brain. 1  For instance, a fast pain message (A-delta fiber) is relayed by the spinal cord to specific locations in the brain, namely the thalamus and cerebral cortex.
