Document Summary
Sensory adaptation- perception that sense simply decreases to the point where we are not aware of it any longer. A sensory impulse is sent to the olfactory bulb and on to the brain. Neural connections between the olfactory bulb and the limbic system explain why smells trigger memories and emotions. Question: what is a consequence of the olfactory senses connection with the limbic system. Receptors for taste are 10,000 taste buds. Question: how many categories of taste can be distinguished by the taste buds in the mouth. Ear drum, cant hear sound without your ear drum (tympanic membrane) marks the beginning of the middle ear. The vibrating tympanic membrane moves the malleus which in turn moves the incus through a joint which then moves the stapes is the final small bone of the middle of the ear. Beyond the stapes lies the oval window, a membrane that functions like the tympanic membrane.
