Muscle morphology can be divided into different can be divided according to the structure and function of the smooth muscle , cardiac muscle, and skeletal muscle of three longus and brevis, wide muscle and orbicularis muscle. Visceral and vascular smooth muscle main components, a slow contraction, durable, easy fatigue, myocardial constitutes the wall of the heart, neither with the contraction of the human will, it is called involuntary muscle. Skeletal muscle distribution in the head, neck, torso and limbs, usually attached to the bone, skeletal muscle contraction quick, powerful, easy fatigue, vasomotor human will, it is called the voluntary muscles. Skeletal muscle was stripes like under the microscope, it is also known as rhabdomyosarcoma.

Skeletal muscle is a dynamic part of the movement system, under the domination of the nervous system , skeletal muscle contraction, traction bones produce movement. A total of more than 600 blocks human skeletal muscle, widely distributed, accounting for about 40% of the body weight, skeletal muscles, regardless of size, have a certain shape, structure, location, and assistive devices, and rich in blood vessels and lymphatic distribution by certain nerve. Therefore, the skeletal muscles can be seen as an organ.

The triceps can be divided into the surface muscle (the expression muscle) and muscles of mastication two parts. Trunk muscles can be divided into the back muscles, chest muscles , the abdominal muscles and the diaphragm. Lower extremity muscle where the site is divided into a hip muscle, leg muscle, calf muscle and foot muscle, stout than upper limb muscle and support weight, maintain an upright and walking-related.

Skeletal muscle

You can see and feel the muscle type. When fitness through exercise to increase muscle strength, exercise is skeletal muscle. Skeletal muscle attached to the bone and occur in pairs: a bone muscles move in one direction, the other one is moved in the opposite direction bones. Usually supplied with the will of the contraction of these muscles means that you want to shrink them, the nervous system will direct them to do so. Skeletal muscle may be a short single contraction (twitch) or long-term sustained contraction (tetanus).

Smooth muscle

Present in the digestive system , blood tubes, bladder , respiratory and women's uterus . Smooth muscle a long time to tighten and maintain tension . This muscle is not under voluntary contraction, means that the nervous system will automatically control them, without the need for people to consider. For example, in the stomach and intestinal muscles every day tasks, but people are generally not aware of.

Myocardial

Exists only in the heart, it is the biggest feature is the endurance and rugged. It can be as smooth muscle limited stretch, can also be used as skeletal muscle as force to shrink. It's just a twitch muscles and not with the will of the contraction.

The roe of muscle

Muscle contraction traction bone joint movement, its role is like a lever device, there are three basic forms (Figure 3-4). (1) the balance lever movement, the fulcrum between focus and force, such as Atlanto-occipital joint upward, and the bow movement. (2) labor-saving lever movement, the focus is located between the fulcrum and the force points, such as the initial lift heel ankle movement. (3) speed lever movement, the force point located between the focus and the fulcrum the elbow of movement such as lifting a heavy object.

Muscle nomenclature

There are many muscles nomenclature, mainly: the shape, such as the trapezius muscle meat, triangular muscle;  by location, such as the supraspinatus muscle, infraspinatus muscle, the tibialis anterior muscle, intercostal muscle meat;  Press the start and end points sternocleidomastoid meat sternohyoid muscle;  by location and size of the pectoralis major muscle meat, the pectoralis minor muscle, the psoas muscle; according to the role, such as supination muscle, great adductor muscle, flexor muscle stretch muscle;  structure, such as the semitendinosus muscle, semimembranosus muscle;  Press the structure and location of the biceps meat, quadriceps meat;  by location and direction of the fibers, such as abdominal external oblique muscle, transverse abdominal muscle and so on.

Assist device muscle fascia, synovial capsule and tendon sheath. They have the to assist muscle activity, to maintain the position of the muscles, and reduce friction in the movement and protection function.somanabolic muscle maximizer product 

(A) fascia

Fascia (fascia) over the body, divided into two kinds of superficial fascia and deep fascia.

1. Superficial fascia (superficial fascia), also known as subcutaneous fascia, located in the dermis below, the package is the whole body, composed of loose connective tissue. Artery and subcutaneous vein, nerve, lymphatic line in the superficial fascia, some local can also have the muscles of the breast and skin. Superficial fascia located deep muscle, blood vessels and nerves have a protective effect, such as the palms and soles of the superficial fascia than those developed to have a dampening effect on the pressure.

2. Deep fascia deep fascia, also known as the inherent fascia consists of dense connective tissue in the superficial fascia deep surface coated body wall, limbs, muscles and blood vessels and nerves. Deep fascia and muscle are very closely related, with the muscle hierarchical and stratified. Human muscle groups in the limbs, deep fascia stretch between and attached to the bone, constitute muscle interval; deep fascia surrounding the muscle groups constitute the fascia sheath; deep fascia surrounding blood vessels, nerves, the formation of blood vessels and nerves sheath; also provide the muscle attachment, or as a muscle starting point.
