The brain combines the input of our two eyes into a single three-dimensional image. In addition, even though the image on the

retina is upside-down because of the focusing action of the lens,

the brain compensates and provides the right-side-up perception.

Experiments have been done with subjects fitted with prisms thatinvert the images. The subjects go through an initial period of

great confusion, but subsequently they perceive the images as

right side up.

TONGUE

The receptors for taste, called taste buds, are situated chiefly in the tongue, but

they are also located in the roof of the mouth and near the pharynx. They areable to detect four basic tastes: salty, sweet, bitter, and sour. The tongue alsocan detect a sensation called "umami" from taste receptors sensitive to aminoacids. Generally, the taste buds close to the tip of the tongue are sensitive tosweet tastes, whereas those in the back of the tongue are sensitive to bitter tastes.The taste buds on top and on the side of the tongue are sensitive to salty andsour tastes. At the base of each taste bud there is a nerve that sends thesensations to the brain. The sense of taste functions in coordination with thesense of smell. The number of taste buds varies substantially from individual toindividual, but greater numbers increase sensitivity. Women, in general, have agreater number of taste buds than men. As in the case of color blindness, somepeople are insensitive to some tastes.

SKINThe sense of touch is distributed throughout the body. Nerve endings in the skinand other parts of the body transmit sensations to the brain. Some parts of the

body have a larger number of nerve endings and, therefore, are more sensitive.

Four kinds of touch sensations can be identified: cold, heat, contact, and pain.

Hairs on the skin magnify the sensitivity and act as an early warning system for

the body. The fingertips and the sexual organs have the greatest concentration ofnerve endings. The sexual organs have "erogenous zones" that when stimulated

start a series of endocrine reactions and motor responses resulting in orgasm.

SMELLThe nose is the organ responsible for the sense of smell. The cavity of the nose is lined withmucous membranes that have smell receptors connected to the olfactory nerve. The smells

themselves consist of vapors of various substances. The smell receptors interact with the

molecules of these vapors and transmit the sensations to the brain. The nose also has a

structure called the vomeronasal organ whose function has not been determined, but which

is suspected of being sensitive to pheromones that influence the reproductive cycle. The

smell receptors are sensitive to seven types of sensations that can be characterized ascamphor, musk, flower, mint, ether, acrid, or putrid. The sense of smell is sometimes

temporarily lost when a person has a cold. Dogs have a sense of smell that is many times

more sensitive than man's.

EARThe ear is the organ of hearing. The outer ear protrudes away from the head and isshaped like a cup to direct sounds toward the tympanic membrane, which

transmits vibrations to the inner ear through a series of small bones in the middle

ear called the malleus, incusand stapes. The inner ear, or cochlea, is a spiral-

shaped chamber covered internally by nerve fibers that react to the vibrations and

transmit impulses to the brain via the auditory nerve. The brain combines the

input of our two ears to determine the direction and distance of sounds.

Surprising Animal Senses

Taste,Smell, andHear.

Did you know that animals also use their senses tolearn about the world?Its true! But animal senses do not always work like

Some animals have senses that are much, much stronger than your senses.

Super Sight

Birds have some of the best eyes of all animals. They look forfood on the ground while they are flying high in the sky. An eaglecan spot its prey from up to a mile away!

Super Smell

A bloodhounds sense of smell is a million times stronger than a

persons sense of smell. That is why bloodhounds are used to track

people who are lost. A bloodhound can use its super nose to track ascent that is nearly four days old.

Super Hearing

Bats can not see in the dark. They use their ears at night to tellwhere

they are flying. They make a high noise and then listen to its echoto know where they are.
