Comparison of somatic and autonomic divisions of the peripheral nervous system Classify the following statements according to the area of the peripheral nervous system they describe. Nerves take sensory information from external receptors to central nervous system Voluntary actions occur in the cerebral cortex Innervates all internal organs Takes motor commands away from central nervous system to the skeletal muscles Somatic System Serves the skin, skeletal muscles, and tendons Composed of sympathetic and parasympathetic divisions Blood pressure and breathing rate reflex actions are maintained Functions automatically and involuntarily For each signal, two motor neurons are utilized Regulates the activity of cardiac muscle, smooth muscle, and glands Autonomic System

Most of the neurons from the fasciculus gracilis synapse in the inferior thoraxand enter the spinocerebellar system, whereas most of the neurons fromthe fasciculus cuneatus synapse in the nucleus cuneatus and then continueto the thalamus and cerebrum. Therefore, it can be deduced that most ofthe proprioception from the lower limbs is unconscious and most of theproprioception from the upper limbs is conscious. Explain why this differencein the two sets of limbs is of value.
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
Suppose that a sensory neuron in the periphery generates a trainof action potentials, and synaptically excites an interneuronin the CNS. What does this signal mean? What additionalinformation does the interneuron need in order to decode themessage?
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?
86. All of the following statementsconcerning the corticospinal tract arecorrect EXCEPT:A. Most of the upper motor neuronshave their cell bodies in the precentralgyrusB. Pyramidal tract axons descendthrough the corona radiataC. Upper motor neurons reach theanterior limb of the internal capsuleD. Pyramidal tract separates intobundles in the midbrainE. Uncrossed pyramidal fibers continueas the ventral corticospinal tract
Watch this video (http://openstaxcollege.org/l/motorpathway) to learn more about the descending motor pathway for the somatic nervous system. The autonomic connections are mentioned, which are covered in another chapter. From this brief video, only some of the descending motor pathway of the somatic nervous system is described. Which division of the pathway is described and which division is left out?
According to the function ofthe transmitted neuralimpulse which are the types ofneurons? How different arethe concepts of afference andefference of the neuralimpulse transmission?

Its' output pathways have two divisions sympathetic and parasympathetic It receives input from enteroreceptors, special and somatic senses It operates under conscious control. It's output pathway is a chain of two neurons.
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?
