Humans are very visual animals...we use
our sense of sight to interpret much of the world around us. What we see is
called "light." However, what we see is really only a small part of
the entire "electromagnetic spectrum."
The ears contain structures for both the
sense of hearing and the sense of balance. The eighth cranial nerve (vestibulocochlear
nerve made up of the auditory and vestibular nerves) carries nerve impulses for
both hearing and balance from the ear to the brain.
The smells of a rose, perfume, freshly
baked bread and cookies...these smells are all made possible because of your
nose and brain. The sense of smell, called olfaction, involves the detection and
perception of chemicals floating in the air.
As you might imagine, smell and taste are
often linked together. The sense of taste is also called gustation.
