What roles do the dendrites, cell body, and axon play in communication of signals?

Open in App

Solution

Dendrites and the cell body receive input signals and the axon conducts nerve impulses (action potentials) and transmits the message to another neuron or effector cell by releasing a neurotransmitter (acetylcholine) at its synaptic end bulbs.
Cell body connects the dendrites to the axon body. They are composed of different organelles like the nucleus, ribosomes, and Nissl's granules. These granules give colouration to the cell body.
