Neurons have different shapes and sizes depending on their roles.A bipolar cell in the retina of the eye collects information from a few inputs and transmits it a short distance to one or more closely spaced neurons.What shape would you predict it to have?
A) A few dendrites and a short axon with one or more terminals
B) A long axon with many axon terminals
C) A dense field of dendrites and a single axon
D) Numerous dendrites and a long axon
E) Dendrites and a highly branched axon

Question

Quizplus · Accepted Answer

A bipolar cell has only a few inputs and transmits information over a short distance, therefore it is likely to have a few dendrites and a short axon with one or more terminals. Option B and D describe neurons that have long axons, which is not indicative of a bipolar cell. Option C describes a neuron with numerous dendrites and a single axon which is also not specific to a bipolar cell. Option E describes a neuron with highly branched axons, which is not necessary for a cell that collects information from a few inputs.
