It is because of the different neurotransmitters and their receptors.
Sympathetic stimulation of arterioles in skeletal muscle is mediated by epinephrine acting on its β-adrenergic receptors.
Sympathetic stimulation of vasoconstriction occurs as a result of activation of α-1 adrenergic receptors by norepinephrine released by post-ganglionic sympathetic neurons.
Answer:
Questions, hypotheses, and ideas should be tested against observable evidence.
Explanation:
Skepticism is extremely important, if not fundamental, in all areas of Science. This attitude is based on the belief that all questions, hypotheses, and ideas should be tested against observable evidence. Moreover, it allows scientists to <u>question and think thoroughly about all possibilities behind a phenomenon, instead of just 'believing' any observation or vague and non-supported reason that explains it.</u>
In addition, it allows researchers to investigate all possibilities and test numerous methodologies to be certain and gather enough evidence to explain this certain phenomenon.
Answer:
compound can be broken down into smaller compound or their basic element by chemical change
Synaptic preganglionic fibers can follow 3 (three) different routes after entering the sympathetic synaptic chain.
<h3>What are synaptic preganglionic fibers?</h3>
Synaptic preganglionic fibers are fibers of the autonomic nervous system that form the paravertebral sympathetic chain ganglia.
The synaptic preganglionic fibers also form the prevertebral ganglia and enters into the sympathetic synaptic chain.
In conclusion, Synaptic preganglionic fibers can follow 3 (three) different routes after entering the sympathetic synaptic chain.
