Muscle Function and Anatomy Concepts

The video tutorial explores the golden rules of muscle motion, emphasizing that muscles can only pull, not push. It discusses the role of muscles in the skeletal system, focusing on how muscles like the zygomaticus and temporalis function. The tutorial explains muscle attachments, contractions, and the concept of origin and insertion. It highlights antagonistic muscle pairs, such as biceps and triceps, and their roles in motion. The video also covers muscle proximity to bones, tendon functions, and how tendons cross joints to facilitate movement.
