Question

Quizplus · Accepted Answer

Dendrites are specialized structures in neurons that receive electrical signals from the synapses of other neurons or from sensory receptors, facilitating the transmission of these signals to the neuron's cell body. They do not typically generate nerve impulses themselves (that's more characteristic of axons), nor are they usually covered with a myelin sheath, which is more characteristic of axons to speed up the transmission of nerve impulses. Additionally, dendrites are not usually the longest nerve fibers; that description fits axons better. Lastly, dendrites are typically shorter and more numerous than axons, which helps in receiving signals from multiple sources.
