What is the primary motor bark?

The primary motor cortex is an area in the brain that works in tandem with other brain areas to coordinate voluntary movement throughout the body. It is located in the frontal lobe along the bumpy area known as the precentral gyrus. The primary motor cortex contains Betz cells, which are large neurons that communicate through the spinal cord axons with alpha motorons. Alpha Motor Neurons are cells responsible for the real perceived movement of the body. The signals initiated by this bark pass through the middle line of the body during acting, which means that the stimulation of the right side of the area controls the left side of the body and vice versa. This means that each part of the body has a subreal in the bark and that these areas are logically placed side by side. For example, a region that controls the action of the foot is next to the Associatory regionueed with a foot or an area that controls most of the movement on the body of the body is adjacent to the arm. The size of the sub -regions that control the specific parts of the body depends on the complexity of the action of the body. For example, one of the largest podoThe bllast in the primary motor bark is devoted to the complicated effect of hands and fingers.

The debate continues between scientists about the scope and the exact mechanism that this area operates. It is assumed that the bark itself does not control individual muscles. Instead, it seems that it directs individual movements or sequences of movements from different muscle groups to perform a voluntary action. Information coded in the primary motor cortex is rather an abstraction of actual movement that alpha neurons perform stimulation.

It has been shown that the primary motor bark helps to encode enforcement contractions using information that is sent back by the peripheral nervous system. For example, the force required to increase the arm varies very much, whether a person holds a bowling ball or a fork. At the same time, the ability to organize various muscle groups helps to create these types of differences. Also helps the body to navigate and encodedirection of movement. Laboratory studies have shown that one cell in the area can shoot more strongly than its counterpart when part of the body moves in one direction.
