Our body's nervous system is build from billions of nerve cells, which are calledQuestion 10Answera.hormones.b.axons.c.neurotransmitters.d.neurons.

Break Down the Problem

1. Identify what the question is asking: The question seeks to identify the term used for nerve cells in the nervous system.

Relevant Concepts

2. Recall relevant biological concepts:
   • Hormones: Chemical messengers that are secreted into the bloodstream.
   • Axons: Long, slender projections of a nerve cell that conduct electrical impulses away from the cell body.
   • Neurotransmitters: Chemicals that transmit signals across a synapse from one neuron to another.
   • Neurons: The basic working units of the nervous system, specialized cells that transmit nerve impulses.

Analysis and Detail

3. Analyze the definitions:
   • Hormones are not cells; they are produced by glands.
   • Axons are parts of neurons, not separate cells.
   • Neurotransmitters are substances released by neurons but are not considered cells themselves.
   • Neurons are indeed the primary cell type in the nervous system.

Verify and Summarize

4. Verify the definitions to ensure accuracy. Based on the established definitions, the majority conclusion leads to neurons being the correct answer to the question.

Final Answer

The correct answer is d. neurons.
