1. Deltoid and Brachialis

   1. Deltoid Action: Shoulder muscles which allow the arms to reach the top of the head in order to do an overhead pass

   2. Deltoid Innervation: Axillary nerve

   3. Brachialis Action: Muscle found at the forearm near the elbow which contracts during the throw of the ball

   4. Brachialis Innervation: Musculocutaneous nerve 

2. Quadriceps and Iliacus

   1. Quadriceps Action: Front thigh needed in kicking to start the motion and generate force

   2. Quadriceps Innervation: Femoral nerve

   3. Iliacus Action: Allows motion in the hips in accordance with the hip muscle to generate a kicking motion

   4. Iliacus Innervation: Femoral nerve

3. Rectus abdominis and Rectus femoris

   1. Rectus abdominis Action: Forward bending motion during sit-ups creates motions within the lumbar portion of the spine

   2. Rectus abdominis Innervation: Thoracoabdominal nerve

   3. Rectus femoris Action: This muscle creates motion in the thigh from the hip all the way to the knees

   4. Rectus femoris Innervation: Femoral nerve

4. Diaphragm and Abdominal

   1. Diaphragm Action: Main muscle for respiration, constantly contracting during breathing

   2. Diaphragm Innervation: Phrenic nerve

   3. Abdominal Action: This muscle main function is to produce abdominal pressure to exhale air

   4. Abdominal Innervation: Thoracic spinal nerves
