Verified step by step guidance1
Step 1: Understand what a synapse is — it is the junction between two neurons where communication occurs.
Step 2: Identify the main types of synapses: chemical synapses and electrical synapses, with mechanical and mixed synapses being less common or specialized.
Step 3: Recognize that chemical synapses use neurotransmitters to transmit signals across a synaptic cleft, allowing for complex and modifiable communication.
Step 4: Note that electrical synapses involve direct electrical coupling through gap junctions, allowing faster but less flexible communication.
Step 5: Conclude that chemical synapses are the most common type in the nervous system due to their versatility and ability to modulate signals.
