This image from MH 091 Skin was obtained with a 60x oil immersion objective. The increased resolution is helpful in viewing the structure of a Meissner's corpuscle.
Meissner's corpuscles are nerve endings in skin responsible for sensitivity to light touch.
They are elliptical structures in direct contact with the undersurface of the epidermis within dermal papillae.
Each corpuscle consists of an unmyelinated axon (not visible by light microscopy) meandering between Schwann cells arranged as horizontal lamellae. The nerve fiber terminates at the superficial pole of the corpuscle.
Meissner's corpuscles are numerous near the tips of the fingers and toes.
