Functional Anatomy: Non-Dominant Arm Tennis Ball Throw
Functional Anatomy
Functional anatomy – Shoulder
Using my knowledge of Functional Anatomy, I can thoroughly asses my non dominant arm tennis ball throw from my preparation phase to my execution phase of the throw. Just looking at the shoulder of my left arm which is a Ball and Socket synovial joint, which is a joint that allows for a large range of different movements. From the preparation phase to the execution phase, my left shoulder is abducted with slight protraction this is because my arm is away from my midline. This is happening due to my agonist muscle which is my deltoids which are contracting and shortening which are pulling my humorous up and away from the middle line of my body. My antagonist muscles are the Pectoralias major and the Latissimus Dorsi which are relaxing and lengthening allowing the movement to occur in a controlled manner. The bones in the shoulder are the Clavicle, the Scapula, and the Humorous

Looking at my left arms elbow, which is a hinge joint. This only allows for a limited range of motion. During the preparation phase of my throw we can see that my left elbow is fully extended. 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
