What is the gap between the axon of one neuron and the dendrite of another called?

The gap between the axon of one neuron and the dendrite of another is known as a synapse. This small gap is where communication between two neurons takes place, allowing for the transfer of neurotransmitters. When an electrical impulse travels down the axon, it triggers the release of these neurotransmitters into the synapse, which then bind to receptors on the neighboring neuron's dendrites. This process is crucial for transmitting signals throughout the nervous system, playing a vital role in various functions, including reflexes, muscle movements, and even complex cognitive processes.

The other terms provided in the choices refer to different aspects of the nervous system. A neural network refers to a series of interconnected neurons working together to process information. Nerve endings are the terminal branches of neurons that interact with other tissues but do not refer specifically to the gap between neurons. The axon terminal is the end part of an axon that releases neurotransmitters into the synapse but does not denote the gap itself. Therefore, the term that most accurately describes the connection point between the axon of one neuron and the dendrite of another is synapse.
