Verified step by step guidance

Understand the basic structure of a neuron, which includes the cell body, dendrites, axon, axon hillock, and synaptic terminals.

Recognize that neurons communicate through electrical impulses and chemical signals. Electrical impulses are crucial for transmitting information along the neuron.

Identify the role of the axon hillock, which is located at the junction between the cell body and the axon. It is responsible for integrating incoming signals from the dendrites and determining whether the threshold for an action potential is reached.

Learn that when the axon hillock reaches a certain threshold of depolarization, it initiates an action potential, converting the integrated signals into an electrical impulse that travels down the axon.

Conclude that the axon hillock is the structure responsible for converting signals into electrical impulses, as it is the site where action potentials are generated.
