Sensory Receptors Quiz

How many senses did Aristotle believe humans have?

• 3

• 5

• 7

• 10

Answer explanation

Aristotle believed humans have 5 senses: sight, hearing, touch, taste, and smell. This classification laid the foundation for understanding sensory perception.

Which sensory receptor responds to light?

• Nociceptors

• Proprioceptors

• Photoreceptors

• Thermoreceptors

Answer explanation

Photoreceptors are specialized sensory receptors that respond to light, allowing us to perceive visual information. Nociceptors detect pain, proprioceptors sense body position, and thermoreceptors respond to temperature.

What receptor nerve cells are involved in touch?

• Hair cells

• Meissner’s corpuscles

• Olfactory cells

• Gustatory cells

Answer explanation

Meissner’s corpuscles are specialized nerve endings located in the skin that respond to light touch. They are crucial for detecting changes in texture and are specifically involved in the sense of touch.

Which nerve cells are involved in taste?

• Gustatory cells

• Olfactory cells

• Hair cells

• Meissner’s corpuscles

Answer explanation

Gustatory cells are specialized nerve cells responsible for detecting taste stimuli. They are located in taste buds on the tongue, making them the correct choice for the question about nerve cells involved in taste.

What happens when a doctor taps your knee with a rubber hammer?

• Your arm moves

• Your leg kicks out

• You sneeze

• You blink

Answer explanation

When a doctor taps your knee with a rubber hammer, it triggers a reflex action causing your leg to kick out. This is known as the patellar reflex, which tests the nervous system's response.

What is the function of the organ of Corti?

• It helps in balancing the body.

• It transmits impulses to the brain as pitch and loudness of sound.

• It filters out background noise.

• It amplifies sound waves.

Answer explanation

The organ of Corti is responsible for converting sound vibrations into electrical impulses, which are then sent to the brain, allowing us to perceive pitch and loudness.

What do cones in the eye do?

• They detect light intensity.

• They allow us to see color.

• They focus light onto the retina.

• They protect the eye from dust.

Answer explanation

Cones are photoreceptor cells in the retina that are responsible for color vision. They allow us to perceive different colors by detecting specific wavelengths of light, unlike rods, which detect light intensity.

What chromosome is related to color blindness?

• Y chromosome

• Z chromosome

• X chromosome

• W chromosome

Answer explanation

Color blindness is primarily linked to the X chromosome, as the genes responsible for the most common forms of color blindness are located there. Males, having one X chromosome, are more affected than females.

Which sensory receptor is involved when you start to sweat from the hot sun?

• Mech (mechanoreceptors)

• Phot (photoreceptors)

• Ther (thermoreceptors)

• Chem (chemoreceptors)

Answer explanation

Thermoreceptors are sensory receptors that detect changes in temperature. When exposed to the hot sun, these receptors trigger sweating as a response to help cool the body down, making 'Ther (thermoreceptors)' the correct choice.
