Final answer:
Meissner's corpuscles, highly sensitive to fine touch and pressure, are concentrated in the glabrous skin, particularly abundant in the fingertips and also present but less numerous in the palms.
Step-by-step explanation:
Tactile (Meissner) corpuscles are specialized sensory receptors that respond to fine touch and pressure. These nerve endings are particularly sensitive to low-frequency vibration or flutter. They are described as rapidly adapting, fluid-filled, encapsulated neurons that can distinguish fine details.
Meissner's corpuscles are abundantly found in areas of the body where touch sensation is critical. They are primarily located in the upper dermis but project into the epidermis. These corpuscles are most concentrated in glabrous skin such as that on the fingertips and eyelids. While they are present in the palms, they are not as plentiful there as in the fingertips. Other tactile receptors include Merkel's disks that are associated with the sense of light touch, Pacinian corpuscles that detect deep pressure and vibration, and Ruffini endings that detect stretch and deformation within joints.
