Schematic of cat’s back showing overlying tissues and the underlying L6 and L7 vertebra. A) Contact sites located on the skin overlying the osseous landmarks. “X” indicates where the center of the manipulator’s tip was placed. See Appendix for standardized method of locating contact sites. B) Contact sites (circles), center of receptive fields (letters), and measurement grid depicting method for determining distance between contact sites and the receptive field for muscle spindle “J”. Distances from each contact site to the center of the afferent’s receptive field were calculated as the hypotenuse h (black lines) of a right triangle with legs a and b (dark gray lines) using h = √a2 + b2. Note x- and y- axes are scaled independently.

SP = spinous process
LAM = lamina
IAP = inferior articular process
MP = mammillary process.
