This is increasing the degree of which my radius is from my humorous. This is occurring because of my agonist muscle the Tricep which is contracting and shortening pulling my Radius and Ulna away from my humorous. My antagonist muscle the Bicep is relaxing and lengthening allowing the extension of my elbow to happen in a controlled manner. The bones which make up the fore arm are the Ulna, and the Radius. My upper arm contains the
