Salivation is entirely under nervous control. Some saliva is secreted continuously in response to parasympathetic stimulation via the vagus nerve. The presence of food in the mouth stimulates the salivary glands to increase their secretions. This response operates through a simple cranial reflex via the vagus nerve. The smell, sight, and thought of food also stimulate salivary secretion.
The vagus nerve (working via the parasympathetic division of the autonomic nervous system) also activates the enteric nervous system. The ENS is responsible for motility, digestion, and secretion (such as HCl, gastrin, histamine in the case of the stomach) throughout the GI tract.
What else can I help you with?
What nerve stimulates normal digestive activity?
Vagus nerve
What is the nerve responsible for regulating visceral activity?
blood pressureThe Vagus Nerve
Which cranial nerve is responsible for regulating visceral activity?
The vagus nerve (cranial nerve X) is responsible for regulating visceral activity. It plays a key role in controlling various internal organs, including the heart, lungs, and digestive system.
What is the most important nerve of the digestive tract?
Vagus nerve
What cranial nerve affects smooth muscle in the stomach?
The cranial nerve that affects smooth muscle in the stomach is the vagus nerve, or cranial nerve X. It plays a crucial role in the autonomic nervous system, particularly in promoting parasympathetic activity, which stimulates digestive processes. The vagus nerve innervates the smooth muscle of the stomach, facilitating peristalsis and the secretion of digestive enzymes.
Where does the vagus nerve go through?
The vagus nerve passes through the neck and enters the thorax where it descends through the chest and abdomen, innervating organs such as the heart, lungs, and digestive system. It is the longest nerve of the autonomic nervous system and plays a key role in regulating many bodily functions.
The vagus nerve is a cranial nerve that carries?
The vagus nerve is the tenth cranial nerve that carries sensory and motor signals between the brain and various organs such as the heart, lungs, and digestive system. It plays a key role in regulating functions like heart rate, digestion, and breathing. Stimulation of the vagus nerve has been used in medical treatments for conditions like epilepsy and depression.
What are the symptoms of vagus nerve damage?
The vagus nerve runs throughout the body and is responsible for the functioning of various bodily systems including the heart and digestive tract. Symptoms of vagus nerve damage include digestive problems, loss of hearing, fainting, pain and difficulty swallowing.
What cranial nerves slows the heart and increases motility of digestive tract?
The vagus nerve (cranial nerve X) slows the heart and increases motility of the digestive tract. It is part of the parasympathetic nervous system which is a branch of the autonomic nervous system.
Most of the digestive system receives its parasympathetic innervation from the?
vagus nerve
Regulates heart activity via the vagus nerve?
The vagus nerve plays a key role in regulating heart activity by controlling the parasympathetic nervous system. Stimulation of the vagus nerve can slow down heart rate and decrease blood pressure, helping to maintain cardiovascular function and stability. It acts as the main connection between the brain and the heart for controlling heart rate and other cardiac functions.
Which cranial nerve controls the heart and lungs?
CN X (Vagus)
