What are the five human senses? What three types of human sense receptor cells give us our 'special senses'?
What are the five flavors humans can taste? How does each taste receptor work? Describe at least one molecule for each of the 5 tastes.
Bitter, sweet, umami, salty, sour. Chewed food mixes with saliva.
What is the name of the nerve that carries sound sensation from the ear to the brain? What is the most common cause of acquired deafness?
Cochlear nerve. Hair cell loss
What are the parts of the eye and what do they do? What structures of the eye does light pass through? List them from first (cornea) to last (retina). What is the name of the nerve that carries visual sensation from the eye to the brain? What type of receptor provides vision? In which structure of the eye are the sensory receptor cells of vision?
Cornea, aqueous humor, pupil, lens, vitreous body, optic disc, retina. Optic nerve. Photoreceptors, rods and cones. Retina
What part of the retina allows humans to see terrific detail? Is this area filled with rods or with cones?
Fovea. Cones
What structure focuses the light that creates your vision? How does the eye regulate the amount of light reaching the retina?
Lens. Iris.
What are the 3 main parts of the ear and what does each do? What part of the ear drains into the back of your throat? What tube takes the drainage to the throat?
Outer ear, actually getting the noise. Middle Ear, turns sound waves into vibrations. Inner Ear, keeps your balance up.
What is your gustatory sense? What type of receptor cells provide this sense?
Perception of taste and flavor. Chemoreceptors
What two types of photoreceptors do humans have? What does each type do? Where in the retina will you find each type of photoreceptor cell?
Rods and Cones. Rods are for low light while cones are for colors. The fastest part of the Retina
Which organ provides your sense of balance? What type of receptor cells do this?
Semicircular canals. Mechanoreceptors
Describe the relationship of sensory receptor cells, sensory neurons, the brain and motor neurons.
Sensory receptors go to sensory neurons, it then goes to the brain and then is perceived as a motor neuron.
Which organ provides your sense of hearing? What type of receptor cell does this? Which part of the ear holds the sensory receptor cells for hearing?
The ear, mechanoreceptors. Cochlea
What causes the blind spot in each of your eyes?
The optic disc
What are nociceptors? What sense do they provide?
They detect pain. Touch
What is your olfactory sense? What type of receptor cells provide this sense? What is the name of the nerve that carries olfactory sensation to the brain?
They detect smell. Chemoreceptors. First cranial nerve or the olfactory nerve.
What are thermoreceptors? What sense do they provide?
They detect temperature change.
What are the five human senses? What three types of human sense receptor cells give us our 'special senses'?
Touch, smell, sight, taste, hear. Mechanoreceptors, chemoreceptors, photoreceptors
