The Gut-Brain Axis The brain shares an intimate connection with the stomach through the gut-brain axis. It’s a two-way connection linking nerves, hormones, and gut flora. The enteric nervous system (ENS), a key component of the brain-gut connection, is often referred to as the ‘second...
and short gastric arteries are responsible for blood supply to the stomach. Celiac ganglia and the vagus nerve innervate the stomach. The vagus nerve serves as an essential link between the brain and the gut respective to appetite control, acid secretion, and gastric motility. ...
The stomach is the digestive system's most dilated portion. This organ lies between the esophagus, which is superior to it, and the small intestine, which is inferior to it. The stomach is a large, muscular, and hollow organ with a great capacity to hold food. This organ can hold about...
Three parallel nerve circuits control stomach emptying: the gutenteric nervous systemfrom the duodenum to the stomach; extrinsic nerves that travel to the prevertebralsympathetic gangliaand return to the stomach by the inhibitory sympathetic nerve fibers; and thevagus nervesto the brain that inhibit ex...
Shunts blood to parts of the body more important for survival, such as the brain and muscles, and away from those less important, such as the skin and digestive system. Suppresses the digestive system so that the body's energies are directed to those systems that are vital for survival. To...
Patients with stab wounds and hypotension, peritonitis, or both should undergo laparotomy immediately. Asymptomatic patients without central nervous system injury (brain or spinal cord injury) or drug or alcohol involvement may be observed with repeated physical exams. In other patients, local wound exp...
The gut is controlled by the enteric nervous system (ENS), a complex system of about 100 million nerves that starts in the brain and ends in the gut. It controls every aspect of digestion, so it's no surprise that when the brain is disturbed, the gut can be as well.The nerve ...
If you’ve ever felt “butterfly in your stomach” when nervous, you’re likely getting signals from your “second” brain. Hidden in the walls of the digestive (消化的) system, this “brain in your gut (肠道)” is changing medicine understanding of the link between digestion, mood and ...
role in removing waste and toxins from the brain and is most active while we sleep, especially on our left side. The brain's ability to efficiently clear metabolic waste through the glymphatic system is what helps our central nervous system. That happens most efficientl...
Stomach-churning and associated symptoms such as nausea, vomiting, loss of appetite, peptic ulcer, and others are commonly caused by stress and anxiety. The reason for this is that the abdomen and the brain share a neural system. Stress hormones are released when someone is upset or anxious,...
