Question

Quizplus · Accepted Answer

Dendrites are branching fibers that get narrower near their ends, which helps them receive signals from other neurons and transmit them towards the cell body. They contain various structures found in most cells, including the nucleus and ribosomes, but they are not an insulating material that cover an axon. They are also not thin fibers of constant diameter, as their shape and size can vary depending on the type of neuron and the location of the dendrites.
