Which cutaneous receptors are concentrated in the fingertips and palms?
A) Meissner corpuscles
B) Pacinian corpuscles
C) Ruffini endings
D) root hair plexus
E) free nerve endings
Meissner Corpuscles
Touch receptors located in the upper dermis, primarily responsible for sensitivity to light touch.
Pacinian Corpuscles
Sensory receptors in the skin sensitive to pressure and vibration, helping organisms perceive touch and pressure changes.
Ruffini Endings
Sensory receptors in the skin that detect stretch, pressure, and heat, contributing to the sense of touch.

Final Answer :
A
Explanation :
Meissner corpuscles are responsible for light touch and are found in high concentrations in the fingertips and palms. Pacinian corpuscles are deep pressure receptors, Ruffini endings detect stretching and distortion, root hair plexus detect hair movement, and free nerve endings detect pain and temperature changes.
