Question

question 1

_____ are sensory receptors responsible for providing the sensation of texture of objects touching the skin.

○ corpuscles of touch
○ lamellated corpuscles
○ root hair plexuses
○ organs of ruffini
○ bulbs of krause
○ free nerve endings

Explanation:

• Corpuscles of touch (Meissner's corpuscles) are located in the dermal papillae, especially in thick skin like fingertips. They are sensitive to light touch and low - frequency vibrations, which helps in discriminating fine textures.
• Lamellated corpuscles (Pacinian corpuscles) are deep in the dermis and hypodermis, sensitive to deep pressure and high - frequency vibrations.
• Root hair plexuses detect hair movement.
• Organs of Ruffini detect skin stretch.
• Bulbs of Krause are thought to be cold receptors (though their function is not fully clear).
• Free nerve endings detect pain, temperature (some types), and crude touch.

Answer:

Corpuscles of touch
