The muscular system is made up of three different types of muscle tissue - skeletal muscle, cardiac muscle and smooth muscle. The skeletal muscles are involved in voluntary actions while the smooth muscles are involved in involuntary actions. The cardiac muscle make up the layers of the heart only. The muscular system works with the skeletal system to bring about movement. e. taking a deep breath: Respiratory diaphragm, external intercostals, sternocleidomastoid and scalene muscles on the neck pointing your toes downward: Plantaris which helps in flexing your ankle and knee and especially while tiptoeing. keeping your seat when riding a horse: Gluteus maximus and glute medius help in sit trotting and maintaining balance and work with the adductor muscles to keep the rider stable in running, the actions at the hip joint: Gluteus maximus, hamstring muscles and the adductor magnus muscle. The primary adductor muscles are also involved - gluteus medius and gluteus minimus muscles touching your chin to your chest: Anterior scalene, sternocleidomastoid, longus capitis, and longus colli shrugging your shoulders: trapezius muscles in standing on your heels, the action at the ankle joint: the medial gastrocnemius, the lateral gastrocnemius and the soleus nodding your head to signify "no": sternocleidomastoid gripping a knife: flexor digitorum profundis and flexor pollicis longus in kicking a football, the actions at the knee joint: Quadriceps group, hamstrings group and plantar flexors closing your jaw, as in chewing: masseter muscle, temporalis and lateral pterygoid placing your palms in the anatomical position: pronator teres and pronator quadratus bringing your arm straight back at the shoulder joint, as in swimming: trapezius and deltoid moving your thigh laterally to take the "at ease" stance: gluteus medius doing sit-ups to tighten your abdomen: iliopsoas, tensor fasciae latae, rectus femoris, sartorius, obliques hunching your shoulders: longus capitis and longus coli, rhomboids and middle, lower trapezius, teres minor and infraspinatus doing Kegel exercises to strengthen the pelvic floor: pubococcygeal muscle bracing your arms when falling forward: Pectoralis major and minor, mid and lower trapezius, the rhomboids and the rotator cuff dropping your shoulders: trapezius, sternocleidomastoid, and levator scapulae muscles while sitting cross-legged, turn the soles of your feet to face each other, the action of turning the soles of your feet to touch each other and the muscles related to that movement: Tibialis posterior and tibialis anterior
