What will be an ideal response?
Dendrites are numerous short, branching projections from a neuron that receive information from other neurons or from the environment. The cell body controls the neuron's metabolic activities and integrates input from other neurons. The axon conducts the nerve impulses away from the cell body. Neurotransmitters are released at synaptic knobs.
