a- Synaptic knobs, also known as synaptic terminals or axon terminals, are involved in the synthesis of neurotransmitters. These neurotransmitters are produced in the neuron and transported to the synaptic knobs.

b- Synaptic knobs release neurotransmitters into the synaptic cleft. This process is known as exocytosis. The neurotransmitters diffuse across the synaptic cleft and bind to receptors on the post-synaptic neuron.

c- Synaptic knobs do have voltage-gated calcium channels. When an action potential reaches the synaptic knob, these channels open and allow calcium ions to enter the knob. This influx of calcium triggers the release of neurotransmitters.

d- Synaptic knobs are located at the terminal ends of axons, not dendrites. They are the point of communication between a neuron and its target cell. The dendrites are the structures that receive signals from other neurons.
