Document Content and Description Below

This is a collection of cell bodies found in the peripheral nervous system. * Answer-Ganglia This part of the autonomic system increases digestion. * Answer-Parasympathetic The dorsal root of a ... nerve contains what type of neurons? * Answer-Sensory (Afferent) This part of a neuron conducts nerve impulses towards the cell body. * Answer-Dendrites An interneuron inside the spinal cord is part of the: * Answer-D. Central nervous system The neuron pictured, below, is best described as: * Answer-Multipolar True or false: Neurons do not physically touch one another. * Answer-True 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-From the peripheral to the central nervous system A postsynaptic neuron would be found: * Answer-After the synapse What is the location and function of Astrocytes? * Answer-Location: Central nervous system (CNS) Function: Regulation of chemical environment inside CNS, forming a physical barrier (blood-brain-barrier) by wrapping around blood capillaries A patient's left thumb was severed in a cooking accident and then reattached during surgery. Would the patient be expected to regrow axons in their thumb? Why or why not? * Answer-Yes; Peripheral nerves can regenerate the length of the axon through axonal regeneration because of the growth of Schwann cells ahead of the axon. 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. * Answer-Afterpolarization (Hyperpolarization) Potassium gates are slow to close and there is an undershoot of the potential. The charge drops below -70mV and then returns to -70mV once at resting state again. [Show More]
