Objective    To provide a morphological basis for clinical muscle transplantation by determining the muscle architectural features and intramuscular nerve distribution of human sartorius.     Methods    The muscle architectural features of human sartorii from 20 human adult cadavers were observed and studied. Modified Sihler’s neural staining technique was utilized to observe the intramuscular nerve distribution of 10 human cadavers.     Results    Human sartorius was composed of long fascicles arranged in parallel. The muscle mass

muscle length

muscle fiber length

pinnate angle and cross-sectional area of human sartorius were (97.9±13.3) g

(47.3±4.3) cm

(40.0±3.8) cm

respectively. Human sartorius wa

s innervated with two primary nerve branches. The secondary nerve branches were independently distributed in the upper part as well as the middle and lower part of sartorius. Compared with the upper part of human sartorius

the middle and lower part of human sartorius has fewer intramuscular nerve branches and anastomoses.     Conclusion    There is a close relationship between intramuscular nerve distribution and muscle architectural features of human sartorius.
