What else can I help you with?
Sympathetic nervous system stimulation causes what?
with stimulation of the sympathetic nervous system there will be a. constriction of the pupils b. dilation of the coronary arteries c. constriction of selected blood vessels d. profuse sweating
Is decrease GI motility and secretion has a cholinergic effect?
Acetylcholine is a neurotransmitter in the GI tract (among other places). An increase in acetylcholine activity (also known as cholinergic activity) results in an increase in GI motility and secretion, not a decrease.
What are the mixing waves in digestive system?
These waves of in the smooth muscles in the GI tract are call peristalsis.
What provides major nerve supply to the GI throat?
The major nerve supply to the gastrointestinal tract, including the throat, primarily comes from the vagus nerve (cranial nerve X). The vagus nerve provides parasympathetic innervation, which regulates various functions such as peristalsis and secretion of digestive enzymes. Additionally, the sympathetic nervous system, particularly through the celiac and mesenteric ganglia, plays a role in modulating GI activity. Together, these neural components coordinate the complex processes of digestion.
The ability of the GI tract to mix and move material along its length is called?
peristalsis, which is the coordinated muscle contractions that propel food and liquids through the gastrointestinal tract.
Sympathetic division stimulation causes?
Increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure.
What is the rhymic contraction of the lining of the gastrointestinal tract called?
The rhythmic contractions of tubular organs, such as the esophagus or intestine, are called peristaltic waves. These waves propel the food material forwards. They are automatic due to local nerve plexus. The peristaltic waves increase in rhythm and force due to stimulation by the parasympathetic autonomic nervous system, and decrease due to stimulation by the sympathetic autonomic nervous system.

This is on a crossword for school. Contractions of GI tract.?
Peristalsis Peristaltic contractions
Stimulation of what receptors would most likely decrease glandular secretions within the GI tract?
muscarinic (M3,M4)
Peristalsis refers to?
Peristalsis is the contraction and propelling movement of the muscular walls of the gastrointestinal (GI) tract.
What do bowel sounds indicate?
peristalsis -- that the GI tract is functioning.
What type of muscle tissue can you find in your livers?
Smooth Muscle would be found in the liver and also throughout the GI tract. Regulated by peristalsis which is regulated by parasympathetic nervous system stimulation by cranial nerve 10 (vagus nerve) by the neurotransmitter acetylcholine ACh.
What are the mixing waves in digestive system?
These waves of in the smooth muscles in the GI tract are call peristalsis.
Rhythm like movement of the muscle in the walls of the GI tract?
The rhythmic movement of muscles in the walls of the gastrointestinal (GI) tract is called peristalsis. It helps propel food and nutrients through the digestive system by contracting and relaxing muscles in a coordinated manner. This movement is essential for digestion and absorption of nutrients.
Name the muscular contraction that is a periodic squeezing of the GI tract that helps to mix and break up chyme?
peristalsis
