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.
1 Sensory neurones carry signals from receptors receptors: organs which recognize and respond to stimuli to the spinal cord and brain. 2  Relay neurones carry messages from one part of the CNS CNS: Central Nervous System (brain and spinal cord). to another.here two neurones meet, there is a tiny gap called a synapse. Signals cross this gap using chemicals. One neurone releases the chemical into the gap. The chemical diffuses across the gap and makes the next neurone transmit an electrical signal.
