Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'Meissner's corpuscle'?

A. An encapsulated nerve receptor present in subpapillary dermis and deep dermis of hairy and glabrous skin.
B. Any of the rapidly adapting mechanoreceptors found in subcutaneous tissue beneath both hairy and glabrous skin, and which normally contain an afferent nerve fiber surrounded by a capsule with multiple concentric layers.
C. The the concept or Herbst corpuscles are a nerve-ending similar to the Pacinian corpuscle, in the mucous membrane of the tongue, in pits on the beak and in other parts of the bodies of birds. It differs from the Pacinian corpuscle in being smaller, in its capsules being more closely approximated, and in that the axis-cylinder in the central clear space is coated with a continuous row of nuclei. In many wading birds, a large number of Herbst corpuscles are found embedded in pits on the mandibles that are believed to enable birds to sense prey under wet sand or soil.
D. A type of nerve ending in the skin that is responsible for sensitivity to light touch. In particular, they have highest sensitivity (lowest threshold) when sensing vibrations lower than 50 Hertz. They are rapidly adaptive receptors.

Answer: A type of nerve ending in the skin that is responsible for sensitivity to light touch. In particular, they have highest sensitivity (lowest threshold) when sensing vibrations lower than 50 Hertz. They are rapidly adaptive receptors.
