Sensory Perception

What is the function of the cornea in the eye?

• The cornea regulates blood flow to the eye.

• The cornea is responsible for color vision.

• The cornea helps with tear production.

• The function of the cornea is to protect the eye and focus light.

Name the three small bones in the middle ear and their functions.

• hammer, anvil, stirrup

• tibia, fibula, patella

• radius, ulna, humerus

• malleus, incus, stapes

How do sound waves travel through the ear?

• Sound waves travel through the ear by passing through the nose and reaching the eardrum.

• Sound waves travel through the ear by being absorbed by the outer ear and then transmitted to the brain.

• Sound waves travel through the ear by directly stimulating the auditory nerve in the brain.

• Sound waves travel through the ear by causing the eardrum to vibrate and transmitting the vibrations to the cochlea in the inner ear.

What are the different types of touch receptors found in the human body?

• Nociceptors, Thermoreceptors, Photoreceptors, and Chemoreceptors

• Gustatory receptors, Olfactory receptors, Photoreceptors, and Auditory receptors

• Baroreceptors, Proprioceptors, Thermoreceptors, and Photoreceptors

• Meissner's corpuscles, Merkel cells, Pacinian corpuscles, and Ruffini endings

Explain the role of the retina in the sense of sight.

• The retina converts light into electrical signals and sends them to the brain.

• The retina produces the pigment that gives color to the eyes.

• The retina filters out unnecessary light before it reaches the brain.

• The retina is responsible for focusing the light onto the lens.

What is the function of the cochlea in the ear?

• The cochlea converts sound vibrations into electrical signals.

• The cochlea helps maintain balance in the ear.

• The cochlea filters out high-frequency sounds.

• The cochlea amplifies sound vibrations.

How does the brain process sensory information received from the eyes, ears, and skin?

• The brain processes sensory information through a series of chemical reactions.

• The brain processes sensory information by analyzing the color and shape of objects.

• The brain processes sensory information through a network of neurons.

• The brain processes sensory information by sending electrical signals to the muscles.

What is the purpose of the lens in the eye?

• To create color perception

• To absorb excess light

• To focus light onto the retina

• To block light from entering the eye

Name the three main parts of the outer ear and their functions.

• earlobe, ear canal, eardrum

• helix, ear canal, eardrum

• lobe, ear canal, eardrum

• pinna, external auditory canal, tympanic membrane

Describe the process of touch sensation from the skin to the brain.

• The process of touch sensation involves the detection of touch by mechanoreceptors in the skin, transmission of signals through sensory neurons to the brain, and processing of these signals in the brain.

• The process of touch sensation involves the detection of touch by thermoreceptors in the skin, transmission of signals through motor neurons to the brain, and processing of these signals in the brain.

• The process of touch sensation involves the detection of touch by chemoreceptors in the skin, transmission of signals through sensory neurons to the spinal cord, and processing of these signals in the spinal cord.

• The process of touch sensation involves the detection of touch by photoreceptors in the skin, transmission of signals through motor neurons to the brain, and processing of these signals in the brain.
