An axon that does not receive enough neurotrophins from a target cell will ____.
A) branch out and form other synapses on other cells
B) manufacture its own neurotrophins
C) degenerate and die
D) fail to reabsorb transmitters that have already been released

Question

Quizplus · Accepted Answer

Without sufficient neurotrophins, the axon is unable to receive the necessary signals for survival and maintenance, leading to degeneration and eventually, cell death. Option A is not necessarily true in this scenario, as branching out may require more resources that the axon cannot afford to spare. Option B is also unlikely as neurotrophins are typically supplied by the target cells. Option D is unrelated to the issue of neurotrophins and transmitter reabsorption.
