  1. Throwing a baseball overhead

    1. Deltoid

      1. Action: assists with shoulder abduction, flexion, and extension

      2. Innervation: axillary nerve, originating from the brachial plexus

    2. Pectoralis Major

      1. Action: assists with shoulder adduction, internal rotation, and flexion

      2. Innervation: medial and lateral pectoral nerves

  2. Kicking a ball

    1. Quadriceps Femoris

      1. Action: knee extension

      2. Innervation: femoral nerve

    2. Hip Flexors (including the Iliopsoas)

      1. Action: hip flexion

      2. Innervation: femoral nerve and lumbar plexus

  3. Doing sit-ups

    1. Rectus Abdominis

      1. Action: flexes the spine

      2. Innervation: lower six thoracoabdominal nerves (T7-T11) and the subcostal nerve (T12)

    2. Obliques (External and Internal)

      1. Action:  trunk rotation, lateral flexion, and forward flexion

      2. Innervation: lower six thoracoabdominal nerves (T7-T11) and the subcostal nerve (T12)

  4. Breathing

    1. Diaphragm

      1. Action: muscle of respiration; when it contracts, it moves downward, increasing the thoracic cavity's volume and drawing air into the lungs; during relaxation, it moves upward, decreasing the thoracic cavity's volume and expelling air from the lungs.

      2. Innervation: phrenic nerve

    2. External Intercostal Muscles

      1. Action: elevate the ribs and expand the thoracic cavity during inhalation

      2. Innervation: intercostal nerves
