HUMAN SKELETAL MUSCLES
This document presented in table format contains information about the skeletal
muscles of the human body. Each muscle’s origin, insertion, innervation, blood
supply, and action are included. In order to aid with memorization and retention, it is
good practice to utilize an anatomy atlas to help visualize the muscles as you study.
