Which nervous system division controls smooth muscle contraction and secretion in the digestive system?
Autonomous nervous system. Consisting of Parasympathetic nervous system and Sympathetic nervous system. Parasympathetic nervous system increases the secretions of digestive tract and Sympathetic system decreases the secretions. Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.

The nerves of the gastrointestinal tract are referred to as?
The nerves of the gastrointestinal tract are referred to as the enteric nervous system. It controls the movement of food and secretions within the digestive system independently of the brain and spinal cord.
What system is the gastrointestinal tract?
The gastrointestinal tract is part of the digestive system, which is responsible for processing food and extracting nutrients to support the body's functions. It consists of various organs including the mouth, esophagus, stomach, small intestine, and large intestine.
4 Stimuli that regulate gastrointestinal tract activity are generated by what?
Stimuli that regulate gastrointestinal tract activity are generated by factors such as nervous system inputs, mechanical stretch of the intestinal wall, chemical stimuli from food and hormones released by the digestive organs. These stimuli play a crucial role in coordinating digestion and absorption processes in the gastrointestinal tract.
Which parts of the gastrointestinal tract are innervated by the somatic nervous system?
GI tract is innervated locally by the enteric nervous system and activity of the Cajal pacemaker cells and by the autonomic nervous system (sympathetic / parasympathetic). It is not innervated by the somatic nervous system. I'm a neurobiologist/physiologist.
What is sympathetic stimulation?
Sympathetic stimulations are signals to the body that imply stress. Sympathetic stimulation stimulates the sympathetic part of the peripheral nervous system and results in multiple response such as increased cardiac output, dilation of the pupil, inhibition of the smooth muscles of the gastrointestinal tract and urinary bladder, and erection of the penis.
What controls the rate and force of the heart beat the secretion of glands of the alimentary tract?
The rate and force of the heart beat are primarily controlled by the autonomic nervous system, specifically the sympathetic and parasympathetic branches. The secretion of glands in the alimentary tract is controlled by various factors, including nervous system input, hormones, and local factors in the gastrointestinal tract.
Which nervous system division controls smooth muscle contraction and secretion in the digestive system?
Autonomous nervous system. Consisting of Parasympathetic nervous system and Sympathetic nervous system. Parasympathetic nervous system increases the secretions of digestive tract and Sympathetic system decreases the secretions. Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.

The nerves of the gastrointestinal tract are referred to as?
The nerves of the gastrointestinal tract are referred to as the enteric nervous system. It controls the movement of food and secretions within the digestive system independently of the brain and spinal cord.
Does the autonomic nervous system control peristalsis?
Yes, the autonomic nervous system (ANS) plays a crucial role in controlling peristalsis, which is the rhythmic contraction of smooth muscles in the gastrointestinal tract. The enteric nervous system, a component of the ANS, specifically regulates these contractions to facilitate the movement of food through the digestive system. It operates independently but is influenced by the sympathetic and parasympathetic branches of the ANS, which can either enhance or inhibit peristaltic activity.
Are the digestive tract and heart enervated by the sympathetic nervous system?
Digestive system has got own local nervous system in the form of myenteric plexus. But then it is supplied by vagus nerve, the tenth cranial nerve, that comes down all the way from your skull. It has got powerful influence on your digestive system. Only terminal part of digestive system gets it's parasympathetic nervous supply from the sacral autonomic outflow.
What effects for both the sympathetic nervous system have on skeletal muscles cardiac muscle and the muscle surrounding the digestive tract?
The sympathetic nervous system stimulates skeletal muscles by increasing blood flow and energy availability, enhancing physical performance during "fight or flight" situations. For cardiac muscle, it increases heart rate and contractility, improving blood circulation to vital organs. In contrast, it inhibits the muscle surrounding the digestive tract, reducing digestive activity and blood flow to the gastrointestinal system, allowing the body to prioritize more critical functions during stress.
Does the digestive system have its own nervous system?
Yes, the digestive system has its own nervous system called the enteric nervous system. This network of neurons controls the function of the gastrointestinal tract independently of the central nervous system. The enteric nervous system helps regulate digestion, absorption of nutrients, and movement of the intestines.
What part of the autonomic nervous system causes an increase in digestive tract mobility?
Stimulation of the Parasympathetic nervous system causes an increase in digestive tract mobility. When stimulated the parasympathetic post-ganglionic neurons release a hormone called Acetylcholine. This causes the Digestive tract to increase its contractions. Counteracting this increase in digestive tract mobility is the sympathetic nervous system, which releases a hormone called noradrenaline which slows down the digestive tracts contractions. This is how the Parasympathetic Nervous System gets the name "rest and digest"
The submucosal and myenteric nerve plexuses that help regulate the mobility and secretory activity of the GI tract organs are both part of the?
The submucosal and myenteric nerve plexuses are both part of the enteric nervous system, which is a division of the autonomic nervous system located in the GI tract walls. They work together to coordinate and regulate the movement, secretion, and absorption processes in the gastrointestinal tract.
