Impulses are conducted towards the nerve cell through the

Step 1: Analyze the question The question asks which part carries impulses towards the nerve cell (the cell body, or cyton).

Step 2: Concept A typical neuron has these parts:

• Dendrites/dendrons: short, branched extensions that receive impulses and carry them towards the cell body.
• Cell body (cyton): contains the nucleus and cytoplasm.
• Axon: a long fibre that carries impulses away from the cell body to other neurons, muscles, or glands.
• Myelin sheath: a fatty insulating layer around the axon that speeds up impulse conduction. It does not receive impulses.
• Synapse: the junction between two neurons. "Synaptic nodes" is not a standard term for a conducting structure.

Step 3: Eliminate the options

• A. Myelin sheath: insulates the axon only. ❌
• B. Dendrons: carry impulses towards the cell body. ✅
• C. Axons: carry impulses away from the cell body. ❌
• D. Synaptic nodes: not a conducting pathway towards the cell. ❌

Step 4: Answer The correct answer is **B.

Tip: Remember "Dendrites Deliver to the cell body; Axons Away." The letters Axon and Away both start with A.
