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.
Hearing and the cochlea. Overview. As sound waves enter the ear, they travel through the outer ear, the external auditory canal, and strike the eardrum causing it to vibrate. The central part of the eardrum is connected to a small bone of the middle ear called the malleus (hammer). As the malleus vibrates, it transmits the sound vibrations to the other two small bones or ossicles of the middle ear, the incus and stapes. As the stapes moves, it pushes a structure called the oval window in and out. This action is passed onto the cochlea, which is a fluid-filled snail-like structure that contains the receptor organ for hearing. The cochlea contains the spiral organ of Corti, which is the receptor organ for hearing. It consists of tiny hair cells that translate the fluid vibration of sounds from its surrounding ducts into electrical impulses that are carried to the brain by sensory nerves.
