Response of carbachol precontracted monkey ciliary muscle to L-arginine (top) and SNP (bottom) illustrating the biphasic nature of the relaxation response. Longitudinal vector (LV), circular vector (CV). Examples of what is referred to as maximum relaxation and minimum relaxation in the presence of the test agent and carbachol are noted. Also, the carbachol change in contraction force is indicated which was used for calculating the % change in responses.
