As well as being partly innervated by the same nerves as the rest of the body, the digestive system also has its own dedicated mini system called the enteric nervous system.
More specifically the innervation of the Stomach is by a few main facets:
Parasympathetic Efferents (outflow) via the Vagus nerve which originates in the brianstem
Sensory Afferents (inflow to the central nervous system) via the Vagus
Sympathetic Efferents from the spinal cord
Sesory Efferents via the spinal cord
To elaboarte on each of these; the Vagal impulses mediate what you could call the 'rest and digest' side of physiological function and increase gastric secretions and motility. On the other hand the parasympathetic efferents do the reverse (Parasympathetic activity via Muscarinic Receptors and Sympathetic Via Adrenergic).
The spinal nerves that particularly supply the (Gastric Plexus) Stomach originate from the Coeliac Plexus and are constituted by the Greater Splanchnic Ganglion and Lesser Splanchnic Ganglion.
These nerves originate from T5-T9 (Greater = T5-9, Lesser = T9-10)
The enteric nervous system refers to intrinsic innervation of the GIT via ganglia just below the mucosa and between the circular and longitudinal smooth muscle. The sensory role of the submucosal plexus is to control glandular secretion whilst the myenteric plexus senses stretch and contraction of the smooth muscle. Increases in stretch immediately increase secretion via reflex integration of the sumbucosal and myenteric plexi.

What cranial nerve is responsible for slowing the heart rate and accelerating peristalsis?
The vagus nerve (cranial nerve X) is responsible for slowing the heart rate (parasympathetic control) and accelerating peristalsis in the gastrointestinal tract.
Which of the cranial nerves is named for the fact that it wanders that is it innervates organs and structures throughout the thorax and abdomen?
The cranial nerve that is named for its wandering nature is the vagus nerve, also known as cranial nerve X. It extends from the brainstem and innervates various organs and structures throughout the thorax and abdomen, including the heart, lungs, and digestive tract. Its extensive reach allows it to play a crucial role in autonomic functions, influencing heart rate, digestion, and respiratory rate.
What cranial nerve is the only one to leave the head and neck area?
The vagus nerve (CN X) is the only cranial nerve that extends beyond the head and neck area. It travels throughout the body, reaching organs such as the heart, lungs, and gastrointestinal tract.
What nerve carries most of the parasympathetic?
The vagus nerve (cranial nerve X) carries most of the parasympathetic fibers in the body. It innervates various organs, including the heart, lungs, and digestive tract, helping to regulate functions such as heart rate, respiratory rate, and gastrointestinal activity. The vagus nerve plays a crucial role in the body's rest-and-digest response, promoting relaxation and energy conservation.
What cranial nerve tract is frequently misidentified as this nerve?
The cranial nerve tract frequently misidentified as the olfactory nerve (Cranial Nerve I) is the optic nerve (Cranial Nerve II). This confusion often arises because both nerves are involved in sensory functions related to the head and can be similarly affected by certain neurological conditions. However, they have distinct functions, with the olfactory nerve responsible for the sense of smell and the optic nerve for vision. Proper identification is crucial for accurate diagnosis and treatment in neurology.

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.
Cranial nerves part of what nervous system?
PNS means peripheral nervous system. CNS means central nervous system.
What is vagus nerve efferent?
The tenth carotid nerve of human is the vagus nerve.A cranial nerve that's a major output of the parasympathetic nervous system. The sympathetic system is fright, fight, or flight enhancer, the parasympathetic is the opposite ... sort of relax and digest your last meal. Slows the heart and increases digestion.
In the gastrointestinal tract where is myenteric plexus?
in wall of GIT the muscularis layer is composed of longitudinal and circuler fibers and the myentric nerve which is the part of enteric nervoius system is present between the longitudinal and circuler fibers
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.
Is sorbitol absorbed by the gastrointestinal tract?
Sorbitol is poorly absorbed by the gastrointestinal tract as it has a low lipid solubility.
What is the abbreviation for gastrointestinal?
GIT. It stands for GASTROINTESTINAL TRACT in full.
