Research Paper Text:

Muscular system is secreted in the whole body by attaching to the frame in the organ system that rules the motor function and forming the wall to internal organs. The muscle that forms the muscle system is an organization that gets excited or tension by stimulation as well as the nerve, and causes the potential action. Muscular shrinks by getting excited for the nerve. This system makes movements of each muscle.

The muscle is classified into three by the difference of the mechanism of the structure and shrinkage. “Smooth muscle” that forms wall of internal organs, “cardiac muscle” is the wall of the heart formed and “skeletal muscle” attached to skeletons.

Skeletal muscles are classified into two. “White muscle” does fast shrinkage in detail for the small movement. ‘Red muscle” does slow and long movement of shrinkage for the maintenance of posture etc.

The muscle system has an important system of heat production besides the system of causing the movement. Skeletal muscles are the organs which produce most of heat. 25% of muscular energy is used for the movement of muscles. 75% of the remainder is used for keeping the body temperatures as the thermal energy.

The living thin gathers individual cells. Therefore, the muscles are formed by gathered cells, too. The cell that forms the muscle is called “muscle fiber”. Bundled and covered ‘muscle fiber” is called “Fascia”.

The muscle fiber of skeletal muscles is covered with the film, the endomysium. It connects with the structure like meshes of a net and the nerve that transmits information to the muscle and the blood vessel that carries blood to the muscle. Skeletal muscles adhere from one bone to other bones. Because skeletal muscles shrink, and loosen, it has the role to move the frame and to fix the joint. Skeletal muscles are “voluntary muscle” that can be shrunk by intention.

Mechanism of muscular shrinkage

The instruction in muscular shrinkage of skeletal muscles is transmitted from the motor nerve through nerve-streak. Moreover, smooth muscle, the excitement transmitted from autonomic to the muscle. The excitements of tensions transmit to the muscle is transmitted to the sarcoplasmic reticulum. The entire muscle shortens because the length of each muscle plate is shrunk because this movement if done in all the muscle plates when the excitement transmits. It returns to former length when the excitement of the muscle ends, and it prepares for the following shrinkage.

About the movement of dog’s tail

Dog’s feeling and excitement appear to the muscle and the hair of the body. Especially, the hair in the vicinity of the spine bristles up, and there is a thing that even the hair of the tail bristles up, too. Because the bone of the tail is connected with the spine as it is, and the part in the root of the tail is especially sensitive, it can be said that the content of transmission is comprehensible if the tail is seen.

When the tension and the excitement become to intense, the movement of the tail bristles up also the hear of the tail (Only the upper part) shows the rise of the nerve in the tail when the dog is strained or gets excited by going as for the nerve though the hair of the scruff of the neck and the back is bristled.

The movement of the tail shows the rise of the nerve. When not only happy but also angering it, the tail is shaken. If the tail is shaken by the bottom, it is shown that I am not comfortable. The tail is hung, and when placing it between legs confidence is lost, and it feels horror. And it is confident expression when shaking it on.

There is an important system on dog’s tail besides the expression of feeling. When run, jumping or swimming, the tail does the role of ‘Rudder’. Especially, it moves to turn the tail greatly when stopping slamming on the brakes when running at Frisbee etc., and the body is balanced. Moreover, the dog sleeps curled up at cold time of winter. The nose is covered with the tail at that time, cold air is not inhaled, and the respiratory organs is protected.

It is important that we untie the muscle by massaging dog’s body, promote circulation of the blood, improve working of the cell, and manage dog’s body. Moreover, the rise of the nerve because of the continuation of the tension and excitement, and softening by massage for the dog with hard muscles also stabilize, and connect felling with heart.
