Document Summary
About 40% of our body mass is skeletal muscle. Know the similarities and differences (by the 2nd exam) Skeletal muscles are the largest of the three. They are multi-nucleated cells that are formed by the fusion of precursor cells. They have a particular pattern of the proteins and the organization of the proteins within them. Cardiac muscle is a single nucleated cell and is intermediate in size of the three types of muscles while smooth is the smallest. Shares features of both types of muscles and is striated. Cells are branched and connect with each other. Do not have the same organizations of the proteins within so they do not have the banding pattern. Skeletal muscles will support and move the skeleton. Cardiac and smooth muscle generate pressure and hallow cavities. As we focus in on skeletal muscle it is important to understand the anatomical- structural hierarchy. Whole muscle is attached bone to bone via tendon.
