Question

The cell body of the neuron responsible for maintaining the life of the cell is known as:

• A. Dendrites
• B. Axon
• C. Soma
• D. Glial cells

Hint:

Think of the soma as the "headquarters" or "life-support system" of the neuron, containing the nucleus and machinery to keep the cell alive. Dendrites are the "receivers," and the axon is the "transmitter."

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The question asks for the name of the part of a neuron that serves as its metabolic center and is essential for its survival.
Step 2: Detailed Explanation:
(A) Dendrites: These are branch-like extensions that receive signals from other neurons and transmit them toward the cell body.
(B) Axon: This is a long, slender projection that conducts electrical impulses away from the neuron's cell body to transmit signals to other neurons.
(C) Soma: The soma is the cell body of the neuron. It contains the nucleus (which houses the genetic material) and other essential organelles, like mitochondria. The soma is responsible for protein synthesis and all the metabolic processes that maintain the neuron's life and function.
(D) Glial cells: These are non-neuronal cells in the nervous system that provide support and protection for neurons. They are separate cells and not a part of the neuron itself.
Step 3: Final Answer:
The cell body responsible for maintaining the life of the neuron is the soma.
