What are the three types of muscle fibers?
1. smooth, intermediate-twitch, cardiac
2. slow-twitch, intermediate-twitch, fast-twitch
3. smooth, cardiac, skeletal
4. slow-twitch, fast-twitch, involuntary
I believe it's four! I'm doing a presentation on the muscular system in my health class and I can send you a link if you think it'll be more help to you in the future
