Structure/Morphology
Bulbous corpuscles are slow adapting mechanoreceptors found in the reticular layer of the dermis, and are especially common on the plantar skin, or soles of the feet. They are highly branched nerve endings that are unmyelinated and traverse between bundles of collagen fibers. Ruffini bulbous corpuscles are located deeper in the dermis than the Krause bulbous corpuscles.
Function
Bulbous corpuscles act as stretch receptors in the dermis. They are also believed to be sensitive to heat.
