Q81.
What causes impulses in the auditory nerve?

a.

Vibrations in the cochlea

b.

Sound waves in the middle ear

c.

Chemical transmitters released by hair cells

d.

Changes in air pressure

Discuss
Answer: (c).Chemical transmitters released by hair cells Explanation:Hair cells in the cochlea bend due to vibrations in the cochlear liquid and release a chemical transmitter, which causes impulses in the auditory nerve.
Q82.
What is pitch?

a.

The amplitude of the sound

b.

The type of the sound

c.

The frequency of the sound

d.

The location of the sound

Discuss
Answer: (c).The frequency of the sound Explanation:Pitch refers to the frequency of the sound.
Q83.
How does the human ear perceive location of sound?

a.

By detecting changes in amplitude

b.

By identifying different instruments

c.

By analyzing frequency changes

d.

By comparing differences in sound reaching the two ears

Discuss
Answer: (d).By comparing differences in sound reaching the two ears Explanation:The two ears receive slightly different sounds due to the time difference and intensity reduction caused by sound waves reflecting from the head, allowing us to perceive the location of sound.
Q84.
Why is touch considered an important sense in our environment?

a.

It provides feedback when interacting with objects.

b.

It enhances visual perception.

c.

It helps in recognizing familiar sounds.

d.

It warns us about potential dangers.

Discuss
Answer: (a).It provides feedback when interacting with objects. Explanation:Touch provides us with vital information about our environment, such as feedback when interacting with objects.
Q85.
How does touch contribute to the experience of using computer systems?

a.

It helps in pressing buttons accurately.

b.

It enhances visual and auditory perception.

c.

It provides warning sounds and notifications.

d.

It enables virtual reality experiences.

Discuss
Answer: (a).It helps in pressing buttons accurately. Explanation:Feeling buttons depress is an important part of pressing them, which contributes to the experience of using computer systems.
Q86.
What type of sensory receptors are involved in touch perception?

a.

Thermoreceptors

b.

Nociceptors

c.

Mechanoreceptors

d.

Photoreceptors

Discuss
Answer: (c).Mechanoreceptors Explanation:Mechanoreceptors respond to pressure and are involved in touch perception.
Q87.
What is the difference between rapidly adapting mechanoreceptors and slowly adapting mechanoreceptors?

a.

Rapidly adapting receptors respond to heat, while slowly adapting receptors respond to pressure.

b.

Rapidly adapting receptors respond quickly to increased pressure, while slowly adapting receptors respond to immediate pressure.

c.

Rapidly adapting receptors respond to continuous pressure, while slowly adapting receptors respond to indented skin.

d.

Rapidly adapting receptors stop responding to continuous pressure, while slowly adapting receptors respond continuously.

Discuss
Answer: (d).Rapidly adapting receptors stop responding to continuous pressure, while slowly adapting receptors respond continuously. Explanation:Rapidly adapting mechanoreceptors respond to immediate pressure but stop responding to continuous pressure, while slowly adapting mechanoreceptors respond continuously to applied pressure.
Q88.
Why is touch important for users with impaired senses?

a.

It compensates for impaired sight and hearing.

b.

It enhances thermoreception and nociception.

c.

It enables virtual reality experiences.

d.

It provides feedback and information in interaction.

Discuss
Answer: (a).It compensates for impaired sight and hearing. Explanation:For those with impaired senses, touch (such as interfaces like braille) may be the primary source of information, compensating for impaired sight and hearing.
Q89.
How can the acuity of different areas of the body be measured?

a.

By measuring the distance between two points on the body

b.

By using pencils and the two-point threshold test

c.

By comparing the sensitivity of different body parts

d.

By assessing the responsiveness of mechanoreceptors

Discuss
Answer: (b).By using pencils and the two-point threshold test Explanation:The two-point threshold test, which involves using pencils held at a certain distance apart to measure the acuity of different areas of the body.
Q90.
Which part of the body typically has the highest acuity according to the two-point threshold test?

a.

Forearm

b.

Finger

c.

Thumb

d.

Leg

Discuss
Answer: (b).Finger Explanation:Fingers and thumbs have the highest acuity, which means they are more sensitive and can detect smaller distances between two points.
