Dendrites are described as?

Explanation:
Dendrites are the input arms of a neuron, designed to receive signals from other neurons or sensory receptors. Their branched structure increases surface area for synaptic contacts, which is why they’re described as branches off of the cell body. They don’t carry outgoing messages—that’s the axon’s job. The nucleus sits in the cell body, not in the dendrites, and ventricles are lined by ependymal cells, not dendrites. So describing dendrites as branches off the cell body best matches their form and role in neuronal communication.
