Document Summary

Lecture 1: structure and function of exercise and muscle. T- tubules: opens to the outside of the cell and are transverse (release calcium) Myofibrils: made up of proteins that allow the muscle to contract. Striated muscle: dark and light areas which is caused by certain muscles and their arrangement. Z-li(cid:374)e: dark li(cid:374)e stru(cid:272)ture (cid:862)z-disk(cid:863) defi(cid:374)es a sar(cid:272)o(cid:373)ere. Sarcomere; smallest functional unit the space that is between one sarcoemere to the next. H zone; lighter area that is inside the a band. M line: dark area within the h zone. Thick filament: runs the width of the a-band to the next. Thick filament: anchored at the z-line and goes into the a-band and ends at the end of the h- zone. Actin: round structure that is strung together. Actin: where the two strands are strung together.
