Dendrites are appendages that are designed to receive communications from other cells.
They take the shape of projections with a tree-like structure that are triggered by other neurons and carry the electrochemical charge to the cell body.
These occupy a large surface area of a neuron.
These little appendages convey electrical stimulation to the soma and take in information from neighboring neurons.
Synapses are also found on dendrites.
Dendrites are also called the "arms" of a neuron.
As it is given in the description, Synapses are also found on dendrites.
Therefore, the parts of the neuron include (A) dendrites.
