Question

which of the following is the point at which two neurons meet?
a gyrl
b ventricles
c synapse
d sulci

Explanation:

• Gyrl: This is not a recognized term in the context of neuron - neuron interaction.
• Ventricles: Ventricles are cavities in the brain that contain cerebrospinal fluid, not related to neuron - neuron meeting points.
• Synapse: A synapse is the junction or point where two neurons meet. It is the site of communication between neurons, where neurotransmitters are released from the presynaptic neuron and can bind to receptors on the postsynaptic neuron.
• Sulci: Sulci are grooves on the surface of the brain, not related to neuron - neuron meeting.

Answer:

C. synapse
