The Musculoskeletal system

There are Three types of muscle are skeletal, smooth and cardiac muscles, The skeletal muscle is the muscle that moves the body, skeletal muscle pull on tendons which are attached to the bone making the body part move, smooth muscle helps your blood to flow better and also helps to push out urine where as the cardiac muscle helps you to pump blood through your body with the main cardiac muscle being you heart.

Agonist and antagonist- Agonist is the muscles which causes movement through the own activation, an example is the triceps brachii contracts, making a shortening contraction, during the up phase of a push-up (elbow extension), An Antagonist is the part when a muscle contracts the other muscle relaxes.

Some Movements in your body are Extension and flexion, Extension is straitening and extending of the joint to increase the angle between two bones or body parts. an example of this is knee extension, When standing up, the knees are extended. An example of Extension is when the hip or shoulder moves the backward towards the side of the body, A Weightlifter for example lifts the weight above head head which then the back hip extends to stay up right, Flexion is the movement which decrease the inner angel of the joint an example is when a bodybuilder flex's to shows his muscle.

 In our class we did an activity which was related to the Musculoskeletal system, the activity involved groups of three which then one person from the group would put on a suit from their the other two would label the bones and muscle that were in the body, This activity helped us to revise with our labelling on the muscle and bones and also the movements that they did, moreover with the body parts that we had gotten wrong we knew what the types of muscle and bones to focus on.
