♥This week we have learned about muscular system. I have learned that muscle is a general form for all contractile of tissue. there are three kinds of muscles : smooth muscle, cardiac muscle, and skeletal muscle. smooth muscle are involuntary and not under our consciousness. These muscles are fond within certain organs, blood vessels, and airways. The second type of muscle is the cardiac muscle, it has a striated appearance and found within the walls of the heart. It makes up the walls of the heart to contract and also it is an involuntary muscle. The third type of muscle is the skeletal muscle, this muscle are fibrous tissues that are attached to our skeletal bones. I also learned the muscle contains a functional units called 'myofibrils' and each fiber must posses many functional contractile units called sarcomeres , this are thick and thin myofilamen.
The reporter of muscular system is Jan, well we can all see that he is not yet ready for his report though sir Gregg gave him enough time. It would have been better if he used a power point presentation as his visual aid so that his report could be easily understand.♥
