Verified step by step guidance

Understand the structure of a neuron: Neurons are composed of three main parts - the cell body (soma), dendrites, and axon.

Identify the function of each part: The dendrites receive signals from other neurons, the axon transmits signals away from the cell body, and the cell body (soma) contains the nucleus and organelles necessary for the cell's survival.

Focus on the cell body (soma): The cell body is responsible for maintaining the life of the neuron as it houses the nucleus and other organelles that produce energy and synthesize proteins.

Consider the role of the nucleus: Located within the cell body, the nucleus contains the cell's genetic material and regulates activities such as growth and metabolism, crucial for cell maintenance.

Conclude that the cell body (soma) is essential for the neuron's survival, as it performs vital functions necessary for maintaining the life of the cell.
