Q

What are the 3 types of Muscle?

-characteristics of each

A

1) Cardiac (LOOK FOR INTERCALATED DISC)
- Striated
- Central Nucleus
- Short, Narrow cell
2) Skeletal
- striated
- peripheral nucli
- singl large, elongated cell
3) Smooth
- NOT Striated
- Central Nuscle
- Single Short, Elongate fusiform (tapered cell
