The peripheral nervous system (PNS) is a system of nerves that connect the central nervous system (CNS) (includes the brain and spinal cord) with other parts of the body. Reflex action is the result of the coordination of the spinal cord and peripheral nervous system. This action does not ...
It is common practice to add tests to requests to expedite diagnosis or clarify the significance of a particular result using algorithms. We devised algorithms for reflex addition of tests which allowed the differentiation of significantly abnormal results as either critical values or those that only ...
a. What do receptors do? b. What can they NOT do? Classify the nervous system into two major parts. Explain the effects of demyelination on action potential propagation and nerve conduction. What are the organs involved in nervous system? Describe the important reflex patterns of movement provid...
Describe the muscle contraction process from the arrival of an action potential at the neuromuscular junction to a full muscle contraction. Define a crossed extensor reflex. What are two mechanisms to increase the strength of a muscle contraction? Describe how nerves, muscles and bones work together...
此外,小脑对植物性反射中枢也有调节作用 The cerebellum is getting up at will to the movement the control action, causes the movement the strength, the speed and the direction is under the precise control.In addition, the cerebellum also has the control action to the plant sexual reflex main ...
One of the most interesting findings as to the role played by the ANS in the occurrence of AF came from the observation that in patients with paroxysmal AF, during pulmonary vein isolation, there was greater efficacy of the procedure in those in whom the evocation of a vagal reflex was dete...
