human muscular system-A



1 comment:

  1. This seems to be a very informative blog. I have bookmarked it and I am looking forward to read more articles written by you. Human beings muscles can be classified in to two, voluntary and involuntary. The voluntary muscles are controlled by us while the involuntary ones work on their own volition and are controlled by the nervous system. We have no control over the muscles that control the heart.
