Verified step by step guidance

Step 1: Understand the basic structure of a neuron, which is the functional unit of the nervous system. Neurons consist of a cell body (soma), dendrites, and an axon.

Step 2: Learn the function of each part of the neuron. The dendrites receive electrical signals from other neurons, the cell body processes these signals, and the axon transmits electrical impulses away from the cell body to other neurons, muscles, or glands.

Step 3: Recognize the role of the myelin sheath. The myelin sheath is a fatty layer that wraps around the axon, insulating it and increasing the speed of electrical impulse transmission, but it is not responsible for transmitting impulses itself.

Step 4: Note that the nucleus is located within the cell body and is responsible for regulating cellular activities, not transmitting impulses.

Step 5: Conclude that the axon is the structure responsible for transmitting electrical impulses away from the cell body, as it is specifically designed for this function in the nervous tissue.
