Sensory System Quiz

What are the main parts of the eye and their functions?

• Sclera, choroid, and vitreous humor - to regulate the amount of light entering the eye

• Eyelid, eyelash, and tear duct - to protect the eye from foreign objects

• Cornea, iris, pupil, lens, retina, and optic nerve

• Conjunctiva, ciliary body, and aqueous humor - to focus light onto the retina

Explain the process of vision in the human eye.

• Vision in the human eye is a result of the brain emitting light to see the surroundings

• Light enters the eye through the cornea, passes through the pupil, is focused by the lens onto the retina, and then converted into electrical signals sent to the brain via the optic nerve.

• Light enters the eye through the ear, passes through the nose, and is converted into sound waves sent to the brain

• The process of vision in the human eye involves the skin absorbing light and transmitting it to the brain

Describe the structure of the retina and its role in vision.

• The retina is a muscle that controls the movement of the eye.

• The retina is the outermost layer of the eye and does not play a role in vision.

• The retina is the innermost layer of the eye that contains photoreceptor cells called rods and cones. These cells convert light into electrical signals that are sent to the brain via the optic nerve, allowing us to perceive visual images.

• The retina contains taste buds and is responsible for the sense of taste.

What are the three main parts of the ear and their functions?

• Left ear, right ear, back ear

• Red ear, blue ear, green ear

• Top ear, bottom ear, side ear

• Outer ear, middle ear, inner ear

How does the ear convert sound waves into electrical signals for the brain to interpret?

• Transmission through the earwax

• Conversion by the eardrum

• Transduction by hair cells in the cochlea

• Amplification by the auditory nerve

Explain the role of the cochlea in the process of hearing.

• It helps to filter out background noise

• It converts sound vibrations into electrical signals for the brain to interpret.

• It is responsible for maintaining balance

• It amplifies the sound waves

What are taste receptors and where are they located in the human body?

• In the lungs and in the stomach

• In the ears and on the skin

• On the tongue and in the oral cavity

• In the eyes and in the nose

How do smell receptors in the nose contribute to the sense of smell?

• Smell receptors in the nose control body temperature

• Smell receptors in the nose aid in digestion

• Smell receptors in the nose help with hearing

• Smell receptors in the nose detect odor molecules in the air and send signals to the brain.

What are touch receptors and where are they found in the skin?

• Muscles and tendons of the skin

• Subcutaneous layer of the skin

• Hair follicles and sweat glands in the skin

• Dermis and epidermis layers of the skin

Explain the difference between fast and slow pressure receptors in the skin.

• Fast pressure receptors respond to sustained pressure, while slow pressure receptors respond to sudden changes in pressure.

• Fast pressure receptors only respond to temperature changes, while slow pressure receptors respond to sustained pressure.

• Fast pressure receptors are located in the muscles, while slow pressure receptors are located in the bones.

• Fast pressure receptors respond to sudden changes in pressure, while slow pressure receptors respond to sustained pressure.
