A Test Organism Develops a Genetic Mutation That Causes Neurons

question 72

Multiple Choice

A test organism develops a genetic mutation that causes neurons to develop without synaptic knobs. How will this impact neuronal function?

• A)Signal transduction down the axon will be interrupted, so the signal will not "jump" the synapse and reach the postsynaptic neuron.
• B)The dendrites of the postsynaptic neurons will have no means to attach to presynaptic axons.
• C)No neurotransmitters will be released into the synapse to signal the postsynaptic neuron, as the synaptic knob is where they are stored.
• D)Action potentials will not travel down the axon nearly as rapidly.
