Fig. 1From: Comparison of cross-sectional area and fat infiltration of suboccipital muscles between normal dogs and dogs with atlantoaxial instabilityComparison of the CSA ratio (A) and the fat ratio (B) of the SOMs between groups. Error bars illustrate that the CSA ratio of SOMs of normal dogs is higher than that of AAI dogs (A) and that group A has the highest the fat ratio of SOMs, followed by group B, with the lowest in normal dogs (B)Back to article page
