This is a collection of cell bodies found in the peripheral nervous system. - Correct Answer: Ganglia This part of the autonomic system increases digestion. - Correct Answer: Parasympathetic The ventral root of a nerve contains what type of neurons? - Correct Answer: Motor This part of a neuron conducts nerve impulses towards the cell body. - Correct Answer: Dendrite A neuron going to the bicep of the forearm is part of the: - Correct Answer: Peripheral Nervous System Somatic Nervous System The neuron pictured, below, is best described as: - Correct Answer: Multipolar True or false: Neurons come into direct physical contact with one another. - Correct Answer: False Describe the function and release of neurotransmitters. - Correct Answer: Neurotransmitters are chemicals stored inside secretory vesicles/ axon terminal vesicles at the end of the axon terminal. When neurotransmitters are released by the axon terminal vesicles they carry the transmission of the nerve impulse from 1 neuron to another. An efferent neuron carries information: - Correct Answer: From the central to the peripheral nervous system A postsynaptic neuron would be found: - Correct Answer: after the synapse What is the location and function of Satellite cells? - Correct Answer: Location - Peripheral Nervous System 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? - Correct Answer: No, only the Peripheral Nervous System axons regenerate. Name and describe what is occurring in the neuron cell membrane in section 4 of the diagram. Include the charge of the membrane during this phase. - Correct Answer: Afterpolarization - K gates close slowly and the potential is undershot The charge drops below -70mV and then returns to -70mV once at resting again
