Final Answer:
The point at which the axon of one neuron meets the dendrite of another and allows nerve impulses to pass is called a Synapse. The correct answer is d) Synapse.
Step-by-step explanation:
A synapse is a specialized junction between two neurons, where the axon of one neuron meets the dendrite of another. This is the fundamental site where nerve impulses are transmitted from one neuron to another.
The synaptic cleft, a small gap, separates the axon terminal of the presynaptic neuron from the postsynaptic neuron's dendritic membrane.
When an action potential reaches the axon terminal, neurotransmitters are released into the synaptic cleft, facilitating the transmission of signals to the postsynaptic neuron. This crucial process allows for communication between neurons, enabling the integration and processing of information in the nervous system.
The other options (a) Cyton, (b) Reflex arc, and (c) Meninx, do not specifically refer to the junction between neurons.
