Brain and heart and gut control
The brain is divided into three parts. The largest and most superior part of the brain is the cerebrum. It is responsible for processing and controlling everything Brain and heart and gut control from movement, autonomic control, decision-making, reasoning, learning, to hearing, speaking and listening, seeing, feeling and emotion. It is the part that separates us from other animals.
The second part, located in the lower part, is the brainstem. Which is further divide into three parts: the midbrain, pons, and medulla.
These parts are responsible for transmitting and receiving signals, and also the point where breathing and heart rate are controlled. It is also the point where 10 of the 12 cranial nerves that come directly out of the brainstem begin.
Finally, it is the connection point between the brain and spinal cord to the body and the cerebellum. Which is the third part that controls balance and rhythm of movement.
Today we will delve deeper into the 10th cranial nerve, the vagus nerve, which is the longest of the 12 nerves and is also the most important nerve in the autonomic, parasympathetic, or resting state nervous system.
The vagus nerve originates in the medulla, the lower part of the spinal cord, and exits with the main artery in the neck. Along the way, it branches off into สมัคร ufabet nerves. That innervate the muscles of the neck and mouth, including the larynx and muscles responsible for swallowing and sensory input from the back of the neck. In addition to innervating Brain and heart and gut control the areas it innervates, the parasympathetic autonomic nerves extend down to the heart, responsible for regulating the heart’s rhythm. Stimulation slows the heart’s rate.
