The following respond to pressure

  1. Meissner's corpuscle

  2. Pacinian corpuscle

  3. Bulbs of Krause

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

There are the different type of stimulus receptors they are mechanoreceptors, chemoreceptors, thermoreceptors, photoreceptors, and electroreceptors. Here, the pressure is a type of mechanoreceptors. Pacinian corpuscle commonly found in deeper tissues of the tendons and ligaments which senses deep pressure. Meissner's corpuscle senses light touch and motion. Bulbs of Krause senses cold and low-frequency vibration. 

So, the correct answer is option B.

Which of the following receptor classifications could be considered enteroreceptors?

  1. Chemoreceptors

  2. Photoreceptors

  3. Visceroreceptors

  4. Both (a) and (c)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Enteroceptor - any receptor that responds to stimuli inside the body.
  • Chemoreceptors: consists of aortic and carotid bodies. Aortic body detects changes in blood oxygen and carbon dioxide, but not pH, while carotid body detects all three.
  • visceroreceptors group of receptors that includes those located in visceral organs. Their stimulation gives rise to poorly localized and ill-defined sensations or to pain. In hollow visceral organs, they are stimulated principally by excessive contraction or by distention.

Since both chemoreceptors and visceroreceptors respond to stimuli inside the body, these can be categorized under enteroreceptors.

So, the correct answer is 'Both (a) and (c)'.

Which of the following are chemoreceptors?

  1. Taste receptors

  2. Olfactory receptors

  3. Auditory receptors

  4. Both (a) and (b)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Chemoreceptors are the receptors that respond to chemicals. Both taste and smell are related to chemical receptors. Therefore, they are chemoreceptors.

So, the correct option is 'Both (a) and (b)'.

D Correct answer
Explanation

(A)Chemoreceptor - Receptor that responds to chemicals.

(B)Photoreceptor - Receptor that responds to light.
(C)Mechanoreceptor - Receptor that responds to pressure, position, acceleration.
(D)Thermoreceptor -Receptor that responds to heat.

The various colours can be detected by

  1. Nose

  2. Skin

  3. Eyes

  4. Both B and C
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • There are two types of photoreceptor cells in the human eye. They are rods and cones.
  • The daylight (photopic) vision and colour vision are functions of cones and the twilight (scotopic) vision is the function of the rods.
  • There are three types of cones which possess their own characteristic photopigments that detect red, green and blue lights.
  • Hence various colours can be detected by Eyes.
  • So, the correct answer is 'Eyes'.

Identify the sense organs.

  1. Eyes

  2. Nose

  3. Tongue

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Sense organs are organs of the body which responds to external stimuli by conveying impulses to the sensory nervous system. For example, eyes, nose, tongue, and ear.
  • We see with our eyes, we smell with our noses, we listen with our ears, we taste with our tongue, and we touch with our skin. Our brain receives signals from each of these organs and interprets them to give us a sense of what's happening around us.
  • So, the correct answer is 'All the above'.

.......... helps to identify the taste of food.

  1. Nose

  2. Skin

  3. Tongue

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • The upper surface of the tongue has small projections called papillae, some of which bear taste buds.
  • About 50 -150 taste cells are found in a taste bud. These cells detect all 4 tastes i.e sweet, sour, salty and bitter.
  • Hence tongue helps to identify the taste of food.
  • So, the correct answer is 'Tongue'.

Organs that helps to detect stimulus from surroundings is called as

  1. Muscles

  2. Sense organs

  3. Blood

  4. None of the above

B Correct answer
Explanation
  • Sense organs are organs of the body which response to external stimuli by conveying impulses to the sensory nervous system.
  • We see with our eyes, we smell with our noses, we listen with our ears, we taste with our tongue, and we touch with our skin. Our brain receives signals from each of these organs and interprets them to give us a sense of what's happening around us.
  • Hence Organs that helps to detect stimulus from surroundings is called as sense organs.
  • So, the correct answer is 'Sense organs'.

Which of the following is a deep pressure receptor scattered in the dermis of our skin?

  1. Phonoreceptor

  2. Meissner's corpuscles

  3. Olfactory receptor

  4. Pacinian corpuscles
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Photoreceptors - These are the structures responsible for light sensitivity.
  • Meissner's corpuscle - They are located in the upper surface of the skin and is sensitive to touch.
  • Olfactory organs - The organs that are responsible for the detection of smell.
  • Pacinian corpuscles - They are embedded deeply into the skin, below the layer of dermis or hypodermis. They act as the receptors for pressure on the skin.
So, the correct option is 'Pacinian corpuscles'.
