SLIDE 66 - PACINIAN CORPUSCLE
This is a sensory receptor for vibratory and deep pressure sense. You will see it later in skin, but this present specimen is a whole mount of mesentery stained with carmine (notice the C.T. fibers, capillaries, and adipose tissue in the background).
Look for large, oval bodies with onion-like layers of specialized connective tissue surrounding a central, dense, red process (the dendritic receptor ending). This is considered an encapsulatednerve ending. In terms of a reflex arc, where do the cell bodies of these endings lie?
