Question

Match the sensation to their corresponding sensory receptors in the skin

$\begin{array}{cc}\text{Sensation}& \text{Sensory receptors}\\ \left(a\right)\text{Temperature}& \left(i\right)\text{Nociceptor}\\ \left(b\right)\text{Touch}& \left(ii\right)\text{Pacinian corpuscle}\\ \left(c\right)\text{Pain}& \left(iii\right)\text{Thermoreceptor}\\ \left(d\right)\text{Pressure}& \left(iv\right)\text{Tactile receptor}\end{array}$

• A. a-iv, b-ii, c-i, d-iii
• B. a-iii, b-iv, c-i, d-ii
• C. a-ii, b-i, c-iii, d-iv
• D. a-i, b-iii, c-iv, d-ii

Answer 1

The correct option is B a-iii, b-iv, c-i, d-ii

$\bullet$ Thermoreceptors are located in the dermal layer of the skin. They are sensitive to temperature.
$\bullet$ Meissner's corpuscles/tactile receptors extend to the epidermal layer. They respond to touch.
$\bullet$ Nociceptors with free nerve endings stretch into the surface of dermis to detect sharp pain.
$\bullet$ Pacinian corpuscles located towards the lower end of dermal layer respond to pressure.
