The type, distribution, and density of encapsulated nerve endings in the hip of the cat were studied by means of the cholinesterase whole-mount staining technique. The capsules of the hip joints of ten cats revealed three basic types of encapsulated nerve endings: simple, elongated, and complex. The numbers and distribution of these types of nerve endings were tabulated for each of the quadrants of each joint: posterior, inferior, anterior, and superior. The highest density of encapsulated nerve endings was found in the inferior quadrant, the lowest in the superior quadrant.
The ligamentum teres contained nerve endings in all but six of the specimens studied.
