the longest part of a nerve cell is called the Axon.
A is for the axon, which is a long, thin extension of a neuron that carries impulses away from the cell body towards other neurons or target cells.

Peripheral nervous system.
Neurons come in many sizes. For example, a single sensory neuron from your fingertip has an axon that extends the length of your arm, while neurons within the brain may extend only a few millimeters. Neurons have different shapes depending on what they do. Motor neurons that control muscle contractions have a cell body on one end, a long axon in the middle and dendrites on the other end; sensory neurons have dendrites on both ends, connected by a long axon with a cell body in the middle.
Yes, an electrical signal is passed from the dendrites of 1 motor neuron, through it's cell body, through it's axon (the long tail looking feature of the neuron). It then travels through branches of the axon and forms synapses with other motor neurons, this is how the electrical signal is passed.
The longest cells are neurons (nerve cells) linking the central nervous system (brain and spinal cord) to other parts of the body. For example, for every receptor cell in your feet, there is a sensory neuron extending from the foot to the base of the spine.
An Axon. I believe that is what you are asking for.
A is for the axon, which is a long, thin extension of a neuron that carries impulses away from the cell body towards other neurons or target cells.
The parts of a generic neuron are:- soma - cell body axon - upto 1 meter long dendrite - many
While axons of the neuron are often mere micrometres thick, they can be up to a meter long (and longer in adults). This makes the neuron the longest cell in the body.
There are actually 3 parts to a neuron. The dendrites are tree branch like projections that receive nerve impulses from another neuron, the cell body that contains the nucleus, and the axon, a long fiber that carries the nerve impulse away from the cell body to the next neuron.
The longest cells are neurons (nerve cells) with a length of 90cm-100cm linking the central nervous system (brain and spinal cord) to other parts of the body.

Each cell type has evolved a shape that is best related to its function. For example, the neuron in Figure below has long, thin extensions (axons and dendrites) that reach out to other nerve cells. The extensions help the neuron pass chemical and electrical messages quickly through the body.
An axon is the long extension of a nerve cell body. The dendrites are the short branches.
The three main parts of a neuron are the soma (cell body), the axons, the long trailing output of a neuron and the dendrite or dendritic tree. Almost all neurons have axons, but not all axons have a dendritic tree.
