Musculoskeletal system

What are the three types of muscles? Three examples of muscles are, cardiac which is the heart, Skeletal, which are all the muscles connected to you bones and smooth muscles which are, stomach, intestines and bladder.
Describe what agonist and antagonist muscles are? Agonist is a movement in a the muscles which contracts, while the antagonist is movement in the muscle which relaxes. An example is when you flex you arm forward, the biceps brachii(agonist) gets smaller where as the triceps brachii(antagonist) lengthens.
What are some movements in the body and examples of the movement in a sport? Some movements in the body are, Knee flexion, elbow flexion, hip extension, hip flexion, etc. An example of hip flexion in a sport is in football, when you kick the ball. When you kick the ball your your hip and leg go back, the agonist is your gluteus maximus and your antagonist is your illopsoas and satorious.

Choose one activity we have completed in class and describe what your task was.
An activity We did was to draw all the muscle and bone that we were learning about on ovaralls a teammate wore. There were 2 sides, on one half was all the bones and on the other half was all the muscles.

  1. Your explanation of agonist and antagonist muscles is clear, and the example you use helps to create a picture of what you are explaining. Just to clarify - moving your leg back as you have explained is hip extension, when you bring the leg forward, this is hip flexion.

    I would have liked to see some pictures in your post Jayden, because there are plenty which you could have included (and would have helped show your activity too). But, this is a great post for you (and your peers) to come back to.
