The Muscular Skeletal System

Muscular Skeletal System :

  • What are the three types of muscles ? (Examples)   
  1. Cardiac - (Example) Heart
  2. Smooth - (Example) Intestines 
  3. Skeletal - (Example) Biceps brachii
  • Choose one activity we have completed in class and describe what your task was
  1. Kahoot : for kahoot we revised the bones and skeletal muscles I worked with my two class friends paris and brodie.
  • Describe what agonist and antagonist muscles are 
  • What are some movements in the body and examples of the movement in a sport ? 
     Example/Sport movement - Pull ups

Agonist - Biceps brachii is the agonist in this movement because the biceps brachii is contracting/shortening. This muscle is the agonist when pulling up (elbow flexion) which is when you pull your body up by bending/contracting your arms(this is elbow flexion) and pull your chin over the bar.

Antagonist - Triceps brachii is the antagonist in this movement because the triceps brachii is extending/lengthening
