Platysma, sternocleidomastoid, trapezius, deltoid, latissimus dorsi, sacrospinalis, pectoralis major, serratus anterior, rectus abdominis, external oblique, internal oblique, biceps brachii, triceps brachii, psoas, gluteus maximus, etc.
There are two types of muscles:
One is the muscle dominated by human consciousness, called voluntary muscle;
The other is a muscle that is not dominated by human consciousness, called involuntary muscle (such as the muscle that transports food to the stomach);
According to the position of muscles, there are pectoral muscles, abdominal muscles, psoas muscles and so on. According to the function, there are flexors and extensors.
According to the shape, there are long muscle, short muscle and platysma muscle. According to the number of muscle heads, there are biceps, triceps and quadriceps femoris; According to the fiber arrangement direction, there are pinnate muscles. Pinnate muscle is divided into pinnate muscle, semi-pinnate muscle and multi-pinnate muscle.
Extended data
Muscle contraction pulls bones to produce joint movement, which acts like a lever device and has three basic forms.
1, the balance bar moves, and the fulcrum is between the key point and the force point, such as the up-and-down movement of the atlanto-occipital joint.
2, labor-saving lever action, its focus is between the fulcrum and the stress point, such as the ankle action when starting to lift the heel.
3. Speed bar movement, the stress point is located between the key and the fulcrum, such as the movement of the elbow joint when lifting heavy objects.
