Which of the following is NOT a type of mechanoreceptor?

  1. Tactile corpuscle

  2. Meissner's corpuscle

  3. Free nerve ending

  4. Thermoreceptor


Correct Option: D
Explanation:

Thermoreceptors are responsible for detecting temperature, not mechanical stimuli.

The sense of touch is primarily mediated by which cranial nerve?

  1. Trigeminal nerve

  2. Facial nerve

  3. Glossopharyngeal nerve

  4. Vagus nerve


Correct Option: A
Explanation:

The trigeminal nerve is responsible for sensation in the face, including the sense of touch.

Which of the following is NOT a function of the somatosensory system?

  1. Detecting pain

  2. Detecting temperature

  3. Detecting proprioception

  4. Detecting visual stimuli


Correct Option: D
Explanation:

The somatosensory system is responsible for detecting touch, pain, temperature, and proprioception, but not visual stimuli.

The ability to perceive fine details of an object's texture is known as:

  1. Tactile acuity

  2. Kinesthesia

  3. Stereognosis

  4. Proprioception


Correct Option: A
Explanation:

Tactile acuity refers to the ability to perceive fine details of an object's texture.

Which of the following is NOT a type of tactile illusion?

  1. Phantom limb syndrome

  2. Two-point discrimination

  3. Size-weight illusion

  4. Referred pain


Correct Option: B
Explanation:

Two-point discrimination is a test of tactile acuity, not an illusion.

The ability to sense the position of one's body parts without visual input is known as:

  1. Kinesthesia

  2. Proprioception

  3. Stereognosis

  4. Tactile acuity


Correct Option: B
Explanation:

Proprioception refers to the ability to sense the position of one's body parts without visual input.

Which of the following is NOT a type of thermoreceptor?

  1. Free nerve ending

  2. Ruffini corpuscle

  3. Krause end bulb

  4. Meissner's corpuscle


Correct Option: D
Explanation:

Meissner's corpuscle is a mechanoreceptor, not a thermoreceptor.

The ability to identify an object by touch without visual input is known as:

  1. Stereognosis

  2. Kinesthesia

  3. Proprioception

  4. Tactile acuity


Correct Option: A
Explanation:

Stereognosis refers to the ability to identify an object by touch without visual input.

Which of the following is NOT a type of pain?

  1. Nociceptive pain

  2. Neuropathic pain

  3. Psychogenic pain

  4. Phantom limb pain


Correct Option: D
Explanation:

Phantom limb pain is a type of neuropathic pain, not a separate category.

The gate control theory of pain suggests that:

  1. Pain signals can be blocked by activating certain nerve fibers.

  2. Pain signals are always transmitted to the brain.

  3. Pain is purely a psychological phenomenon.

  4. Pain is always caused by tissue damage.


Correct Option: A
Explanation:

The gate control theory of pain suggests that pain signals can be blocked by activating certain nerve fibers, which close a 'gate' in the spinal cord.

Which of the following is NOT a type of touch receptor?

  1. Tactile corpuscle

  2. Meissner's corpuscle

  3. Free nerve ending

  4. Photoreceptor


Correct Option: D
Explanation:

Photoreceptors are responsible for detecting light, not touch.

The ability to perceive the weight of an object is known as:

  1. Kinesthesia

  2. Proprioception

  3. Stereognosis

  4. Baresthesia


Correct Option: D
Explanation:

Baresthesia refers to the ability to perceive the weight of an object.

Which of the following is NOT a type of somatosensory cortex?

  1. Primary somatosensory cortex

  2. Secondary somatosensory cortex

  3. Parietal association cortex

  4. Visual cortex


Correct Option: D
Explanation:

The visual cortex is responsible for processing visual information, not somatosensory information.

The ability to perceive the shape of an object is known as:

  1. Stereognosis

  2. Kinesthesia

  3. Proprioception

  4. Tactile acuity


Correct Option: A
Explanation:

Stereognosis refers to the ability to perceive the shape of an object by touch.

Which of the following is NOT a type of tactile agnosia?

  1. Astereognosis

  2. Agraphesthesia

  3. Prosopagnosia

  4. Anosognosia


Correct Option: C
Explanation:

Prosopagnosia is a type of visual agnosia, not tactile agnosia.
