Does parasympathetic have postganglionic axons secrete norepinephrine?
No, parasympathetic postganglionic axons secrete the neurotransmitter acetylcholine, not norepinephrine. Norepinephrine is the primary neurotransmitter used by postganglionic neurons of the sympathetic nervous system.
Are Efferent neurons are the most abundant type of neuron?
Efferent neurons are not the most abundant type of neuron, as interneurons make up the majority of neurons in the central nervous system. Efferent neurons, also known as motor neurons, transmit signals from the central nervous system to muscles and glands to elicit a response.
What do all regenerated fibers have in common?
Regenerated fibers are all produced from natural materials, such as cellulose from plants or proteins from animals. They are chemically processed to create new fibers that resemble natural fibers like cotton or silk. Regenerated fibers are known for their sustainability and eco-friendly properties.
What is the basic chemical substance of all synthetic fibers?
The basic chemical substance of all synthetic fibers is polymer. Polymers are long chains of repeating molecular units that are synthesized through chemical reactions to create fibers with specific properties like durability and flexibility.
Which nervous system controls the voluntary function of the limbs and the sense organs?
The muscle fibers are functionally organized as motor units. A motor unit consists of a single motor neuron and all of the muscle fibers it innervates.Whole muscles exhibit characteristics that are more complex than those of individual muscle fibers or motor units. Instead of responding in an all-or-none fashion, whole muscles respond to stimuli in a graded fashion, which means that the strength of the contractions can range from weak to strong.
Does parasympathetic have postganglionic axons secrete norepinephrine?
No, parasympathetic postganglionic axons secrete the neurotransmitter acetylcholine, not norepinephrine. Norepinephrine is the primary neurotransmitter used by postganglionic neurons of the sympathetic nervous system.
Do all visceral motor neurons synapse in a sympathetic ganglion?
No; some axons synapse in nearby autonomic ganglion. postganglionic fibers travel along either sympathetic nerves or rejoin at the spinal nerve.
Is the aorta an afferent or efferent blood vessel?
Afferent means going towards; efferent means going away from. In reference to the heart, all veins, including the inferior and superior vena cavae, are afferent. All arteries are efferent.
Will the efferent explode?
All organs can be damaged; the term explosion is not adequate.
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.

Do all rational numbers terminate?
Yes

Can all Jedi terminate hunger and thirst?
Probably not
In the periodontal ligament the fibers are the most numerous and make up the bulk of all fibers?
the oblique fibers
What are staple fibers?
Staple fibers are short, non-continuous fibers. All natural fibers, except silk, come in staple form.
Difference between afferent and efferent in kidney?
Efferent means going away from and afferent is going toward. The afferent arteriole of the kidney carrys blood toward the glomerulus, whereas the efferent arteriole carrys blood away from the glomerulus.
What power of attorney does not terminate upon death?
All power of attorney grants terminate upon death. They can only represent a living person.
