검증된 단계별 안내1
Step 1: Understand the structure of a neuron. Neurons are specialized cells that transmit signals in the nervous system. Key parts include the axon, dendrites, and cell body.
Step 2: Learn how neurons communicate. Neurons do not physically touch each other; instead, they communicate across a small gap between them.
Step 3: Define the term 'synaptic cleft.' The synaptic cleft is the small gap between the axon terminal of one neuron and the dendrites or cell body of another neuron, where neurotransmitters are released to transmit signals.
Step 4: Review the other options provided. The Node of Ranvier refers to gaps in the myelin sheath along the axon, the Myelin sheath is a protective covering around the axon, and the Axon hillock is the part of the neuron where the axon connects to the cell body.
Step 5: Conclude that the correct answer is 'Synaptic cleft,' as it specifically refers to the gap between two neurons where signal transmission occurs.
