The muscles of the cat are more than 500.

Cutaneous muscles . They give expression to his face. They are very thin and are located immediately below the skin. Of great importance for the study of the behavior and in neurology; allow you to bend your ears, close your eyelids, show your teeth.

From the jaw . The digastric is responsible for the opening of the jaw. The temporal, the masseter and the pterygoid allow it to close effectively.

Neck flexors . Branquicephalic, sternocephalic and ventral cervical. They are complex and numerous. They swing the head, move the shoulder forward, etc.

Extenders of the spine. They make up the common mass of dorsal cervical spines and muscles and intervene active in stopping jumps and races. If they contract independently on the right or left side, they allow for abrupt changes of direction.

Flexors of the loins. The abdominals (outer and inner oblique and rectum of the abdomen ) and psoas are essential for capturing the power and flexibility of the spine.

Arm extensors . The branquiocephalic and the supraspinatus lengthen the stride, allowing the arm to get ahead a lot and prepare the reception after a jump. Arm flexors . The large dorsal, triceps brachii and ascending pectoral make the arm cling to the ground back in the fast races. Very powerful, these muscles also participate when the cat climbs.

Forearm Extenders . The triceps brachii, the most powerful muscle of the anterior limb, makes such an important function as propulsion possible by flexing the arm and extending the forearm.

Flexors of the hand. The antibranquial caudals favor the cat to grip the ground back after the propulsion (one of them, the flexor of the fingers, allows the cat to pull
voluntary claws, which usually remain retracted thanks to a small dorsal ligament.)

Thigh extensors . Thanks to them, the powerful buttocks have a primordial propulsive function.

Leg extensors. The femoral quadriceps is largely responsible for the range of jumps you can perform the cat.

Leg flexors. The hamstring muscles make the limb stay stuck to the body after the propulsion.

Flexors of the foot and extensors of the fingers. The cranial tibials, like their counterparts in the anterior limb, put the foot in position before touching the ground.

Foot extensors and finger flexors . The tibial caudals also participate in propulsion, but are less powerful than the quadriceps or buttocks.

Tail muscles . They are very numerous and, thanks to this, they allow the member so much mobility and they play an important role in balancing and expressing behaviors.
