What is the differences between myocardial muscles and skeletal muscles?
Skeletal muscles: packed together, attach to, and cover the skeleton. obvious striations. VOLUNTARY muscles. contract rapidly but TIRE EASILY. responsible for overal body motility. extrememly adaptable (can exert forces from only onces to 70 lbs) Cardiac (myocardial): only in the heart. striated and NOT VOLUNTARY. contracts at a steady rate. contolled by nervous system and bodily changes. ONCE YOU LOSE IT, ITS GONE FOR GOOD. CAN'T FATIGUE. has to have stimulus great enough to stimulate all of the muscles of none will contract (where as skeletal muscles can be forced into twiches where only a small part of the muscle will contract)
