Question

Quizplus · Accepted Answer

Structures that move from the cell body of a neuron down the axon toward the neuron terminals are said to move in an anterograde direction. This is because this direction is towards the front end of the neuron, which is where the axon terminals are located. Retrograde refers to movement in the opposite direction, from the axon terminals towards the cell body. The other choices, astronomical, radial, and intergrade, are not terms used to describe the direction of movement of structures within neurons.
