Watch this video (http://openstaxcollege.org/l/motorpathway) to learn more about the descending motorpathway for the somatic nervous system. The autonomicconnections are mentioned, which are covered in anotherchapter. From this brief video, only some of the descendingmotor pathway of the somatic nervous system is described.Which division of the pathway is described and whichdivision is left out?
Regeneration of a severed axon has a better chance forsuccess in the PNS than in the CNS. Why is regeneration inthe CNS less likely to succeed?
Contrast the somatic nervous system with the ANS foreach of the following:a. number of neurons between the CNS and the effectororganb. location of neuron cell bodiesc. structures each innervatesd. inhibitory or excitatory effectse. conscious or unconscious controlf. neurotransmitter(s) used
Visit this site (http://openstaxcollege.org/l/neurolab)to see a virtual neurophysiology lab, and to observeelectrophysiological processes in the nervous system,where scientists directly measure the electrical signalsproduced by neurons. Often, the action potentials occur sorapidly that watching a screen to see them occur is nothelpful. A speaker is powered by the signals recorded froma neuron and it “pops” each time the neuron fires an actionpotential. These action potentials are firing so fast that itsounds like static on the radio. Electrophysiologists canrecognize the patterns within that static to understand whatis happening. Why is the leech model used for measuringthe electrical activity of neurons instead of using humans?
what type of diet pattern must be followed to have the nervous sytem function optimally
Using your knowledge of normal physiology, list theeffects of increased sympathetic nervous systemstimulation on body function and muscle tone.
There are two divisions of the autonomic nervous system: Sympathetic and parasympathetic What are the functions of each system?
Students in a veterinary school are given the following hypotheticalproblem: A dog ingests organophosphate poison, and the students areresponsible for saving the animal’s life. Organophosphate poisons bindto and inhibit acetylcholinesterase. Several substances the studentscould inject include the following: acetylcholine, curare (which blocksacetylcholine receptors), and potassium chloride. If you were a studentin the class, what would you advise to save the animal?
The peripheral nervous system’s efferent or motor division may be broken into two broad categories. Please shortly describe their importance to human body homeostasis.
Imagine that you are hiking in the mountains one afternoon with friends. As you turn acorner, you come across a lion standing in the middle of the trail.a. Identify the specific division of the nervous system that is responsible for thebody’s response to this situation.b. Describe at least six physiological responses you might have upon seeing thebears.c. Indicate the division of the nervous system that is responsible for returning thebody back to equilibrium after the event is over.
