The bulboid corpuscles (end-bulbs of Krause) are cutaneous receptors in the human body.

The end-bulbs of Krause were named after German anatomist Wilhelm Krause (1833-1910).[1][2]

FunctionEdit

They were once thought to mediate temperature but are now known to have the ability to detect low-frequency vibration.

StructureEdit

They are minute cylindrical or oval bodies, consisting of a capsule formed by the expansion of the connective-tissue sheath of a medullated fiber, and containing a soft semifluid core in which the axis-cylinder terminates either in a bulbous extremity or in a coiled-up plexiform mass.

LocationEdit

They are found typically in mucocutaneous zones, those tissues that are transitional between dry glabrous skin and mucus membranes,

For eample they are found in the:

  • conjunctiva of the eye (where they are spheroidal in shape in humans, but cylindrical in most other animals),
  • mucous membrane of the lips and tongue,
  • epineurium of nerve trunks.
  • penis and the clitoris and have received the name of genital corpuscles; in these situations they have a mulberry-like appearance, being constricted by connective-tissue septa into from two to six knob-like masses.
  • synovial membranes of certain joints, e. g., those of the fingers, rounded or oval end-bulbs occur, and are designated articular end-bulbs.
