  • Back
sensory receptors located on the tongue that result in taste perception.
taste buds
thin layer of tissue found at the back of the eye made up of light receptors and sensory neurons.
retina
receptor cells in the retina that are adapted for vision in dim light; also help detect shape and movement.
rod
receptor cells in the retina adapted for sharp vision in bright light and color detection.
cone
snail-shaped structure in the inner ear containing fluid and hairs; produces electrical impulses that the brain interprets as sound.
cochlea
structures in the inner ear containing fluid and hairs that help the body maintain balance.
semicircular canals
Summarize the different types of messages the senses receive.
The eyes respond to light. The ears respond to sound. Touch receptors respond to mechanical stimulation. The tongue and nose respond to chemicals
When you have a cold, why is it difficult to taste food?
The tasting of food involves both the sense of smell and the sense of taste. When your nose is stuffed up, therefore, you can't taste as well.
Explain how your eyes detect light and images.
Light stimulates the rod or cone cells in the retina, which transmit a signal to the brain through the optic nerve
List the different types of receptors that are found in the skin.
touch, temperature, pressure, and pain
Why might an ear infection lead to problems with balance?
Swelling associated with an ear infection could cause fluid in the ear to put pressure on the semicircular canals and cause the hairs in the canals to signal a false sense of balance in the brain.
List the sequence of structures through which sound waves pass to reach the auditory nerve.
outer ear, eardrum, malleus, incus, and stapes, fluid of cochlea, hairs of cochlea, auditory nerve to the brain
