This organ contains taste buds that detect sweet, salty, sour, bitter, and umami flavors.
What is the tongue?
This structure in the brain receives signals from smell receptors and processes odors.
What is the olfactory bulb?
This part of the eye controls the amount of light that enters by changing the size of the pupil.
What is the iris?
This small membrane at the end of the ear canal vibrates when sound waves hit it.
What is the eardrum (tympanic membrane)?
This is the body’s largest organ and contains receptors for touch sensations.
What is the skin?
These tiny sensory structures on the tongue house the receptors responsible for taste perception.
What are taste buds?
This mucus-lined area at the top of the nasal cavity contains the receptors for smell.
What is the olfactory epithelium?
This lobe of the brain processes visual information received from the eyes.
What is the occipital lobe?
This spiral-shaped structure in the inner ear converts sound vibrations into nerve signals.
What is the cochlea?
This sense allows you to know where your body parts are without looking at them.
What is proprioception?
This fluid produced by the salivary glands helps dissolve food chemicals so taste receptors can detect them.
What is saliva?
These airborne substances bind to receptors in the nose to create the sensation of smell.
What are odor molecules (or odorants)?
This transparent structure at the front of the eye helps focus incoming light.
What is the cornea?
This nerve carries sound information from the inner ear to the brain.
What is the auditory (cochlear) nerve?
This outermost layer of the skin provides a waterproof barrier and helps protect against infection.
What is the epidermis?
Once considered the fifth basic taste, this savory flavor is commonly associated with foods like mushrooms and soy sauce.
What is umami?
The olfactory system can help humans detect dangers such as this invisible, odorless gas that companies add scent to for safety.
What is natural gas?
This nerve carries visual information from the retina to the brain.
What is the optic nerve?
These three tiny bones in the middle ear amplify sound vibrations.
What are the malleus, incus, and stapes?
These glands produce sweat to help regulate body temperature.
What are sweat glands?
This part of the brain processes taste information received from the gustatory receptors.
What is the gustatory cortex?
This sense works closely with taste to help identify flavors in food.
What is smell (olfaction)?
This part of the eye contains the photoreceptors that convert light into neural signals.
What is the retina?
This condition involves partial or complete inability to hear and can result from damage to the ear or auditory nerve.
What is hearing loss (deafness)?
This middle layer of skin contains blood vessels, hair follicles, sweat glands, and sensory receptors.
What is the dermis?
