Neurotransmitters carry signals across the ________ ________.
- A. refractory gap
- B. axonal gap
- C. synaptic gap
- D. hippocampal gap
Correct Answer: C
Rationale: Neurotransmitters carry signals across the synaptic gap, also known as the synaptic cleft, which is the small space between the terminal button of one neuron and the dendrite of another. When an action potential reaches the terminal button, neurotransmitters are released into the synaptic gap and bind to receptors on the postsynaptic neuron, facilitating communication between neurons. This process is essential for neural signaling and brain function.
