Enteric nervous system

The enteric nervous system (ENS) is primarily in charge of controlling most of bowel and gut movements and is a relatively new concept. The ENS is made up of multiple ganglia that function organs including: the small and large intestines, stomach, liver, gallbladder, appendix, and pancreas. Hirschsprung’s disease can result from a mutation of the ENS. Hirschsprung’s disease is a condition where the colon partially forms due to the mutant genes that have preceded it during the development of the enteric nervous system. Hirschsprung’s disease can be caused by failure of the pathway from BMP, SOX10, RET receptor tyrosine kinase, endothelin-3 and EDNRB, CDX 1 and CDX 2, and FOXA1 and DUSP6. ENTERIC NERVOUS SYSTEM Overview The enteric nervous…

seen in various regions of the brain upon post mortem examination. Lewy Bodies are a rather obscure area of research and it is not known whether they are the direct cause of neuronal death. However, several studies have proven that Lewy Bodies have the ability to spread from cell to cell and propagate to other parts of the body: when ventral tissue from the fetal midbrain is transplanted into the SN of PD patients, Lewy Bodies can be found in the new tissue after several years (REFERENCE); and…

lost makes it a progressive disorder of the nervous system. The National Parkinson Foundation states on their website that the most substantial area of degeneration is the Substantia Nigra in the brain which produces dopamine. Before symptoms occur, roughly 60%-80% of the neurons in the Substantia Nigra have diminished. Dopamine allows for communication between neurons that can control movement. With less dopamine in the brain, a person develops motor symptoms of Parkinson’s. According to the…

are elicited by the stretch stimulation of the walls of the intestine, are mediated by the depolarization of the intrinsic primary neurons within the myenteric plexus that contains nerves that are essential for the peristalsis reflex, thus instigating the release of excitatory neurotransmitter (Furness, 2000). The release of the excitatory neurons then results in the stimulation of excitatory or inhibitory motor neurons, which prompts the contraction or relaxation of the smooth muscle…

Role of the Brain, Nervous System, & Sensory Systems In humans, the nervous system is the area in which the body processes and sends messages. It is a complicated system that gathers sensory information from the entire body, replies to changes in the body, evaluates request information, begins and implements all bodily activity, and preserves “homeostasis” in the body. An organism nervous system is separated into two systems: the “central nervous system (CNS) and the peripheral nervous system…

The nervous system is the system in our bodies that transmits signals to and from various parts of the body. It helps control the body and somewhat connects the body together. The nervous system is key to communication with all the parts of the body. Without the nervous system, people would not be able to perform certain functions in the body or be able to sense when things are dangerous. The nervous system is composed of primarily two parts: the central nervous system and the peripheral nervous…

no:16472374 The nervous system and neuron communication The nervous system is a highly complex and broad area of biopsychology. People depend on the nervous system for their survival and safety.This essay will explore the components from which the nervous system is composed and their main functions. This essay will also decipher the mechanisms through which neurons communicate. According to Carlson (2014) the Nervous system is branched into two categories - the central nervous system (CNS)…

gland is stimulated by its parasympathetic nerve. a) Describe the organization of the parasympathetic division of the autonomic nervous system The autonomic nervous system (ANS) is a part of the peripheral nervous system that largely acts involuntarily. It consists of nerves in cardiac muscle, smooth muscle, exocrine and endocrine glands. The main visceral activities are temperature regulation, digestion, blood pressure and genitourinary function. The second main division of the peripheral…

Logos, or the means of persuasion by use of reasoning, is a very effective rhetorical strategy that appeals to the reader’s logic. Not only is logos Aristotle’s favorite form of rhetoric but, it is the most widely used rhetorical form. Logos is composed of both inductive and deductive reasoning and in “Does the internet make you dumb” Nicholas car uses both to prove his thesis that the internet is turning us into “superficial and scatterbrained thinkers (Carr 218). He believes the internet is…

In 1944, Ralph H.Baer invented the words “video games”, and then created the first console in 1966, launching a billion dollar industry of future games to come. Games began as non-violent competition. Today they have become more and more vehement. The Age of technology has taken over many teenagers’ lives. What began as a fun activity is now an obsession for the video gamer. Although video games are entertaining, teens should not waste their time playing video games because the games will…
