The answer is true. The nerve cell is the primary unit of communication in the neurological system (neuron). The cell body, a primary branching fiber (axon), and numerous smaller branching fibers comprise each nerve cell (dendrites). Nerve cells (neurones) are 'excitable' cells that may convert a range of stimuli into electrical impulses, continuously delivering information about the external
The internal environment to the central nervous system (in the form of sequences of action potentials) (CNS). Except for sponges and placozoa, the neuron is the primary component of neural tissue in all animals. Plants and fungi, for example, lack nerve cells.
