Muscles

What are the three types of muscles?
The three types of muscles are cardiac, smooth and skeletal. The skeletal muscle is a type of striated muscle, attached to the skeleton. Cardiac muscle contracts, it pumps blood into the heart and through the blood vessels of the circulatory system. The smooth muscle forms organs like the stomach, bladder, veins
Describe what agonist and antagonist muscles are?
Antagonist and agonist muscles is when one muscle contracts, the other relaxes. For example elbow extension, if i was stretching out my arm my triceps are contracted and my Biceps are relaxing.
What are some movements in the body and examples of the movement in a sport?
For example if i was playing softball  my movement is elbow abduction. When the ball is pitched the persons arm is stretching out the bat which the triceps are contracted and the biceps are relaxing until the person pulls back his arm its addiction. 


Choose one activity we have completed in class and describe what your task was.
One activity we did was to get into groups of 3 and write all the muscles and bones. One person had to stand up on the other side and we had to put the labels on that persons body. Mrs Doughty called a muscle/Bone and we had to put exactly where the bone/muscle is. The activity was very useful and fun.

Hey Texas, I love the pictures you have included in your post! Just to help you understand a little more - shoulder abduction is when you move your arm out to the side, and shoulder adduction is moving your arm back to the body. I think you might be a little confused about the movements, so I would recommend some revision of these. Your description of agonist and antagonist muscles is great though - one shortens and one contracts.

NICE! Texas I really like the way you have explained your participation also the way you were telling others that you were really enjoying it and the way you have showed what our p.e class is like with the photos. But just one thing is just try and remember the bullet points about some more information of the participation.
