| colloid corpuscle | One of a number of small ovoid or rounded, sometimes laminated, bodies resembling a grain of starch and found in nervous tissue, in the prostate, and in pulmonary alveoli; of little pathological significance, and apparently derived from degenerated cells or proteinaceous secretions. Synonym: amniotic corpuscle, amylaceous corpuscle, amyloid corpuscle, colloid corpuscle. (05 Mar 2000) |

| Purkinje's corpuscle | <neurology, pathology> A class of output neurons in the cerebellum, which are the only neurons that convey signals away from the cerebellum. They form a layer of large ganglion cells near the surface of the cerebellum. Origin: From J. E. Purkinje, their discoverer. (12 Dec 1998) |
