Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten, or remain the same. Although the term contraction implies shortening, when referring to the muscular system, it means muscle fibers generating tension with the help of motor neurons (the terms twitch tension, twitch force, and fiber contraction are also used).

In the contraction of a skeletal muscle calcium acts to trigger the muscle for contraction. This occurs by removing the inhibition of troponin.

the stock is the wooden part that you hold against your shoulder, the trigger mechanism and the barrel are attached to it.





The sear is the part, usually moved by the trigger, that releases the striking mechanism, so that the cartridge is fired.


At the "balance" of the weapon. Just forward of the trigger mechanism. And practice a lot.


The pump is a pull-down located on the barrel, and the 12-shot loader is a cylinder integrated in the gun just past the trigger mechanism and before the barrel. I've tried dismantling it, but to no avail. the air cilinder (located on the barrel) does not seem to touch any of the springs associated with the firing/trigger mechanism. Blocked? or a missing part that fits into the air cylinder If someone can explain how the mechanism works i can see if everythings there. thank you.

When you pull the trigger the hammer (which was cocked back before) is released and it hits the primer on the cartridge which sets off the powder in the cartridge, and the bullet is propelled forward.

Regulatory molecules are commonly types of proteins which will regulate the functions of the muscles. The interaction of actin and myosin is regulated which will trigger muscle contraction.
