Document Content and Description Below

This is a bundle of axons found in the peripheral nervous system. * Answer-nerve This part of the autonomic system accelerates the heart beat and increases breathing rate. * Answer-sympathetic nerv... ous system The ventral root of a nerve contains what type of neurons? * Answer-motor (efferent) This part of a neuron conducts nerve impulses towards the cell body. * Answer-denderites A neuron going to the bicep of the forearm is part of the: * Answer-A. Central nervous system B. Peripheral nervous system C. Autonomic system D. Somatic system E. A&C Correct! F. B&D The neuron pictured, below, is best described as: * Answer-A) Bipolar B) Correct! Multipolar C) Unipolar D) Pseudounipolar True or false: Neurons do not physically touch one another. * Answer-True Neurons do not physically touch. They are separated by synapses. Describe the synthesis and storage of neurotransmitters. * Answer-The neuron cell body manufactures neurotransmitters, which are stored in secretory vesicles at the end of axon terminals. An afferent neuron carries information: * Answer-A) From the central to the peripheral nervous system B) Correct Answer From the peripheral to the central nervous system C) Within the central nervous system D) Within the peripheral nervous system A presynaptic neuron would be found: * Answer-A) Correct Answer Before the synapse B) After the synapse C) Inside the synapse D) Only in the peripheral nervous system What is the location and function of Satellite cells? * Answer-Location: Peripheral nervous system (PNS) Function: Regulation of environment of neuron cell bodies A patient's spinal cord was severed in a car accident. Would the patient be expected to regrow axons in their spinal cord? Why or why not? * Answer-No; Only peripheral system axons are capable of regeneration. The spinal cord is in the central nervous system. Name and describe what is occurring in the [Show More]
