What gland produces catecholamines?
"Catecholamines are produced mainly by the chromaffin cells of the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Dopamine, which acts as a neurotransmitter in the central nervous system, is largely produced in neuronal cell bodies in two areas of the brainstem: the substantia nigra and the ventral tegmental area. The similarly melanin-pigmented cell bodies of the locus ceruleus produce norepinephrine." - WikipediaThe main catecholamines are epinephrine and norepinephrine, which are produced in the adrenal medulla (in the adrenal glands). Dopamine is the other, which is from neuronal cell bodies.
How drugs affect the nervous system?
Depressant Drugs: Alcohol, Benzodiazepines, Barbiturates and other central nervous system depressant drugs act primarily on a neurotransmitter substance known as GABA (Gamma Aminobutyric Acid). GABA is an inhibitory neurotransmitter that makes other neurons less likely to activate. The depressant drugs are GABA agonists, acting to help GABA reduce neuronal activation more efficiently than it usually would. Alcohol also inhibits (acts as an antagonist against) another excitatory neurotransmitter (Glutamate), making it harder for Glutamate to get the nervous system excited. Stimulant Drugs Amphetamines have their primary effects on the neurotransmitter Dopamine. Amphetamines both induce the terminal button of Dopamine-producing neurons to let more Dopamine out than normal, and also keep that Dopamine out in the synapse longer than it normally would be allowed to stay. Amphetamine also acts agonistically on receptors for a different neurotransmitter, Norepinephrine, by competing with Norepinephrine for post-synaptic receptors and turning those post-synaptic receptors on. Cocaine has its major effect by blocking the re-uptake of the neurotransmitters Dopamine and Serotonin. Opioid Drugs: Opioid drugs bind to special endorphin receptors in the brain (the 'mu', 'kappa', 'sigma' 'delta' and 'gamma' receptors) that have to do with pain. When these receptors are occupied and activated, the perception of pain lessens. Drug treatments for opioid addictions sometimes include the administration of Naltrexone, which is an opioid antagonist. Naltrexone competes with the opioids for their receptor sites, but is not itself capable of activating those receptor sites. An opioid addict on Naltrexone is thus rendered more or less incapable of getting high from their opioid drug of choice; they may take an opioid, but it will be blocked from the opioid receptors by the Naltrexone, and will not have its effect. Cannabinoids: Marijuana has a complex set of effects. It acts on the neurotransmitters Serotonin, Dopamine and Acetylcholine. It also binds to a receptor for a recently discovered neurotransmitter known as Anadamide. Hallucinogens: LSD is known to antagonize Serotonin by blocking its release.

What is the cause of manic-depressive illness?
Manic Depressive Illness or Bipolar Disorder is caused by disturbance in brain chemistry. Though not fully understood it is found that neurotransmitters like serotonin and dopamine in certain areas of the limbic system function poorly. Medicines like mood stabilizers and selective serotonin reuptake inhibitors correct neuronal transmission to produce near normal functionality.
Site of the nucleus and most important metabolic area?
Neuronal cell body
What is a Neuronal cell body?
The soma
What are neuronal varicosities?
vb cvbcbcxn
What is the importance in a reverberation neuronal pool?
there is no importance
What is the prognosis for patients with neuronal migration disorder?
Due to the congenital nature of neuronal migration disorders, most patients do not recover from their symptoms. The course of disease tends to be static.
What is the part of the neuron that carries impulses to the body?
Synapses. Net flow of charged ions ("impulses") in neuronal cells trigger additional ion flow (ionotropic signaling) or neurotransmitter release (metabotropic signaling) to both neuronal and non-neuronal cell types ("the body") at junctions called synapses.
How does the respiratry system work?
combination of mechanical and neuronal activitiy
