how process is governed by the autonomic nervous system?
By release of chemical neurotransmitters like epinephrine and norepinephrine, increasing response to tough external stimuli.
Two major neurotransmitters of the autonomic nervous system?
You have acetylcholine liberated at ganglion in both sympathetic and parasympathetic nervous system. You have noradrenaline secreted at post ganglionic sympathetic nerve terminals. You have acetylcholine secreted at post ganglionic parasympathetic nerve terminals.
Which autonomic neurons release norepinephrine as a neurotransmitte?
Sympathetic postganglionic neurons release norepinephrine,
What are the two neurotransmitters that axon terminals of autonomic neurons release?
Nonepinephrine and acetylcholine
The portion of the nervous system that controls involuntary activities is a subdivision of the what nervous system?
Autonomic
Which nervous system subdivision is a chain of two motor neurons consisting of a preganglionic and a postganglionic neuron?
autonomic
As part of which nervous system do postganglionic neurons release norepinephrine?
Sympathetic nervous system, which is part of autonomic nervous system.
Which division of the autonomic nervous system is involved in secreting norepinephrine via adrenergic nerve fibers?
Sympathetic nervous system .
Which of subdivision of nervous system serves as communication lines linking all parts of the body to central nervous system?
autonomic nervous system
What are the two subdivisions of the motor subdivision of the peripheral nervous system?
The two subdivisions of the motor subdivision are the somatic nervous system and the autonomic nervous system. The somatic nervous system transmits action potentials from the CNS to skeletal muscle, and the autonomic nervous system transmits action potentials from the CNS to smooth muscle, cardiac muscle, and glands.
Why the symptoms of hyperthyroidism may be confused with a disorder of the autonomic nervous system?
Hyperthyroidism may be confused with a disorder fo the autonomic nervous system primarily because of the the permissiveness (biology) of the thyroid hormones on the hormones and neurotransmitters (epinephrine and norepinephrine) of the sympathetic division of the autonomic nervous system. Thyroid hormones exacerbate the effect of the sympathetic nervous system, causing "speeding up" of various body systems and symptoms resembling an overdose of epinephrine (adrenaline). These include fast heart beat and symptoms of palpitations, nervous system tremor such as of the hands and anxiety symptoms, digestive system hypermotility (diarrhea), considerable weight loss and unusually low lipid panel (cholesterol) levels as indicated by a blood test.
What is the difference between epinepherin and norepinepherin?
Epinephrine and norepinephrine are two very structurally similar molecules. They've both involved in the sympathetic part of your autonomic nervous system. Epinephrine (also known as adrenaline) is a hormone which is secreted from the adrenal medulla when activated by the sympathetic nervous system (during times of stress). Norepinephrine (also known as noradrenaline) is a neurotransmitter that is released by neurons in the sympathetic nervous system. Epinephrine and norepinephrine generally produce the same effects as they both interact with adrenergic receptors in the body. Epinephrine is structurally different from norepinephrine as epinephrine has a methyl group (-CH3) attached to the nitrogen atom (making it a secondary amine), whereas norepinephrine is just a primary amine.
