Central nervous system (CNS) and peripheral nervous system (PNS) are two systems innervous system that control human movement and activity.(a) Describe the pathway of receiving and transferring information in neuron.
Two separate post-synaptic interneurons receive synaptic potentials from afferent neurons in the periphery. The dendrites of one these interneurons receive an excitatory post-synaptic potential (EPSP) and an inhibitory post-synaptic potential (IPSP) of equal magnitude at the same time. The dendrites of the other interneuron receive one excitatory post-synaptic potential that is the same sized as the EPSP and IPSP received by the other interneuron

- Match each region of the central nervous system with some of its functions.arrow_forwardIn what way does the interior surface of the cell membrane of a resting (non-conducting) neuron differ from the external environment? The interior is: positively charged and contains less sodium. negatively charged and contains less sodium. negatively charged and contains less potassium positively charged and contains more sodium.arrow_forwardSuppose that a neuroanatomist performed two experiments on an animal with the same basic brainstem structure as a human’s: In experiment 1, he selectively transected (cut across) the pyramids on the anterior side of the medulla oblongata; and in experiment 2, he selectively transected the gracile and cuneate fasciculi on the posterior side. How would the outcomes of the two experiments differ?arrow_forward
- Sensory fibers, or pathways, are referred to as “afferent.” Motor fibers, or pathways, are referred to as “efferent.” What can you infer about the meaning of these two terms (afferent and efferent) in a structural or anatomical context?arrow_forwardsometimes the terms neuron and nerve are mistakenly used interchangeably. explain the difference between the two structures.arrow_forwardWhat is the difference between Central and Peripheral Nervous System?arrow_forward
- Which statement is TRUE about the synapse? Neurotransmitters shuttle the signal back and forth between the pre- and post-synaptic cell. The pre-synaptic cell and post-synaptic cell are in direct contact, allowing the electrical signal to seamlessly flow from one to the other. The action potential jumps from the pre-synaptic cell into the post-synaptic cell. The action potential ends in the pre-synaptic cell and neurotransmitters carry the signal across the synaptic cleft to the post-synaptic cell.arrow_forwardFill in the descriptions for the following terms as they relate to the PNS or CNS neural tissue: Tract: Bundles of [ Select ] ["axons", "cell bodies"] in the [ Select ] ["CNS", "PNS"] Nerve: Bundles of [ Select ] ["axons", "cell bodies"] in the [ Select ] ["CNS", "PNS"] Ganglion: Bundles of [ Select ] ["axons", "cell bodies"] in the [ Select ] ["CNS", "PNS"] Nucleus: Bundles of [ Select ] ["axons", "cell bodies"] in the [ Select ] ["CNS", "PNS"]arrow_forwardWhich of these alternatives shows the correct order for a neuron that is leaving the spine? Think of the neuron starting at the spinal cord and an exiting the spine, going to your chest. What would be the path? It would travel out of the spine into the spinal nerve, past the dorsal branch and into the rootlet of the chest. into a spinal nerve, then into a ventral root and then into an anterior branch past a rootlet, into a ventral branch, past a dorsal root, and then to the chest past a rootlet, into a ventral root, into a spinal nerve and then into an anterior brancharrow_forward
