Neurotransmitter acetylcholine has a major role in what behavioral function?
Muscle Movement Cognitive functioning
What is behavioral envionment?
i believe behavioral environment transpires as: the environment that we live in has an effect on each individuals behaviour.
What is the effect of pilocarpine on heart rate?
Pilocarpine stimulates the release of acetylcholine from parasympathetic neurons. Therefore, it stimulates the effect of vagal stimulation on the heart.
What is an example of acetylcholine?
acetylcholine
What effect will organopesticides have on muscle tissue?
Organopesticides will increase the severity of muscle contraction beyond normal conditions. Acetylcholine esterase inhibition will allow a more than normal amount of acetylcholine to bind to receptors.
Acetylcholine is an example of what neurotransmitter?
acetylcholine
What is the main neurotransmitter of the parasympathetic autonomic nervous system?
Parasympathetic system has acetylcholine as its chemical mediator.
The chemical that transmits the signal across the neuromuscular junction is called?
Acetylcholine
Why does acetylcholine causes vaso-dilation?
In some muscle tissue acetylcholine causes vaso-dilation, but not all. Norepinephrine is the opposite competor/effector of acetylcholine. Acetylcholine is present in all preganglionic fibers, both parasympathetic and sympathetic. Acetylcholine is present in postganglionic parasympatic fibers, where norepinephrine is present in the postganglionic sympathetic fibers. In some tissues acetylcholine causes constriction. Can also reduce heart rate vi the vagus nerve. Acetylcholine is the only neurotransmitter used in the somatic nervous system! Acetylcholine can effect vasodilation by several mechanisms, including activation of endothelial nitric oxide (NO) synthase and prostaglandin (PG) production. In human skin, exogenous Acetylcholine increases both skin blood flow and bioavailable NO levels, but the relative increase is much greater in skin blood flow than NO. So this may lead us to speculate that acetylcholine may dilate cutaneous blood vessels through PGs, as well as NO. In some muscle tissue acetylcholine causes vaso-dilation, but not all.

What neurotransmitter is found at the synapse between nerves and human skeletal muscle cells?
Acetylcholine is the neurotransmitter at the neuromuscular junction.
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.
Is the effect of a neurotransmitter on the muscle cell membrane to modify its ion permeability properties temporarily?
Acetylcholine
