Neuron Synapse Infographic, Human Blood Vessels Diagram Style

Biological diagram infographic titled "Neuron Synapse" centered around a clean labeled cross-section of a human chemical synapse between two neurons, educational and simple for kids ages 8–12, with the presynaptic terminal on the left, synaptic cleft in the center, and postsynaptic dendrite on the right. Render an editorial-grade anatomical cross-section in medical illustration (Netter-style), monochrome scientific palette with soft grays, charcoal linework, subtle shading, and calm academic mood. Show 7 labeled components arranged evenly around the central diagram, each connected by a thin leader line, each with a short English label and a one-line English function caption, all sharp and highly readable. Include these exact labels and captions: "Axon Terminal" — "Sends the signal to the next cell."; "Synaptic Vesicles" — "Store chemical messengers called neurotransmitters."; "Neurotransmitter" — "Carries the message across the gap."; "Synaptic Cleft" — "Tiny space between two nerve cells."; "Receptor" — "Receives the chemical message on the next cell."; "Postsynaptic Dendrite" — "Takes in the signal from the synapse."; "Mitochondrion" — "Provides energy for synapse activity." Ensure biologically accurate neuronal anatomy and proportions, tasteful educational presentation, no blood or gore. Add a small unobtrusive legend style note for signal direction using English text: "Signal direction" with a clear arrow from presynaptic side to postsynaptic side. Composition should emphasize the membrane boundaries, vesicle release, neurotransmitters diffusing across the cleft, and receptor binding. medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no graphic gore, no real patient photos, no watermarks No graphic medical gore, no real patient photographs, no surgical blood. For human anatomy, keep illustrations educationally tasteful. For animal anatomy, no cruelty imagery. Scientifically accurate labeling and proportions.
