summary of the video with the time for reference:
1) Anconeus
-15% activity
-carries out elbow extension and stabilizes in supination and pronation
2)Triceps Brachii
-long head
-medial Head
-short Head
3)Medial and Lateral head
-Uniarticular muscle
-High extensor moment, around 70 to 90%
3)Long head
-Biiarticular muscle
-Very low extensor moment
-Active insufficiency is seen with shoulder extension
4)Synergistic Activity 4:52
-Biceps and triceps together create pure supination.
-All the muscles around the elbow joint together create stability.
