Explanation: 

Detailed explanation-1: -A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells.

Detailed explanation-2: -Cell body. Also known as a soma, the cell body is the core section of the neuron. The cell body contains genetic information, maintains the neuron’s structure, and provides energy to drive activities. Like other cell bodies, a neuron’s soma contains a nucleus and specialized organelles.

Detailed explanation-3: -The structure of a motor neuron can be divided into three components: the dendrites, the cell body (soma), and the axon. They are multipolar in structure, which means they possess a single axon and multiple dendrites.
