A histochemical survey was done on the fiber composition of 12 different locomotory muscles in the lizard Dipsosaurus dorsalis. Three types of fibers were found in all muscles: (1) fast-twitch-glycolytic (FG); (2) fast-twitch-oxidative-glycolytic (FOG); and (3) tonic fibers. Virtually all locomotory muscles contain some tonic fibers. Most muscles have bulk white regions (containing mostly FG fibers) and distinct red, oxidative regions (with FOG and tonic fibers). These red regions are predominantly located around the joints in the hind limb muscles, and probably serve a postural and joint-stabilizing function. The predominance of FG fibers in the bulk white regions is well-correlated with the rapid, anaerobically supported predator escape behavior of D. dosalis.
对沙漠角蜥（Dipsosaurus dorsalis）12种不同运动肌肉的纤维组成进行了组织化学研究。在所有肌肉中发现了三种类型的纤维：（1）快肌糖酵解型（FG）；（2）快肌氧化糖酵解型（FOG）；以及（3）慢肌纤维。几乎所有的运动肌肉都含有一些慢肌纤维。大多数肌肉有大量白色区域（主要包含FG纤维）和明显的红色氧化区域（含有FOG和慢肌纤维）。这些红色区域主要位于后肢肌肉的关节周围，可能起到姿势维持和关节稳定的作用。大量白色区域中FG纤维的优势与沙漠角蜥快速的、由无氧支持的捕食者逃避行为密切相关。
