Composition of the rat psoas major muscle
Introduction. Rat psoas major muscle arises from lumbar vertebrae and inserts at the lesser trochanter of the femur. Unlike humans, the rat is a quadruped, and only occasionally rises on its hind legs. Therefore, composition of the rat psoas major muscle is expected to differ in relation to humans. Material and methods. Psoas major muscles of male Wistar rats were analyzed and Type I, IIA, IIB and IIX muscle fibers were typed using myosin heavy chain identification. Results. Rat psoas major muscle had predominance of fast type IIB muscle fibers with the largest cross-sectional area. Slow type I muscle fibers were present with the lowest percentage. Moreover, type I muscle fibers, together with type IIA muscle fibers, had the smallest cross- sectional area. Conclusion. Predominance of the fast muscle fiber types in the rat psoas major muscle indicates its primarily dynamic function in contrast to humans’ psoas major muscle whose composition indicates its dynamic as well as postural function.
