Verified step by step guidance1
Understand the structure of a neuron: Neurons have several key parts including dendrites, the cell body (which contains the nucleus), the axon, and the axon hillock.
Learn the function of dendrites: Dendrites receive signals from other neurons and convey this information to the cell body.
Explore the role of the axon: The axon is responsible for transmitting electrical impulses away from the cell body to other neurons, muscles, or glands.
Focus on the axon hillock: The axon hillock is a specialized part of the cell body where the axon begins. It is crucial for integrating signals from multiple inputs.
Understand signal integration: The axon hillock is where excitatory and inhibitory inputs are summed up. If the combined signal is strong enough to reach the threshold, an action potential is generated and travels down the axon.
