Chemical Synapse Structure Comparison Infographic Diagram

Biological diagram infographic titled "Chemical Synapse Structure Comparison" centered on a clean labeled diagram comparing two neuronal synapse structures side by side: a typical excitatory synapse and a typical inhibitory synapse, shown as editorial-grade anatomical cross-sections with aligned pre-synaptic terminal, synaptic cleft, and post-synaptic membrane for direct visual comparison. Use a comparison layout with the two structures mirrored left and right around a central divider, with 9 labeled parts total arranged around the composition using thin leader lines. Each label must include a short heading in English and a one-line function description in English. Labels to render exactly as: "Presynaptic Terminal" — "Axon ending that stores and releases neurotransmitter."; "Synaptic Vesicles" — "Membrane sacs that package chemical messenger molecules."; "Voltage-Gated Calcium Channels" — "Open during depolarization to trigger vesicle fusion."; "Active Zone" — "Specialized release site where vesicles dock and exocytose."; "Synaptic Cleft" — "Narrow extracellular gap across which neurotransmitters diffuse."; "Postsynaptic Receptors" — "Membrane proteins that detect neurotransmitter and start a response."; "Postsynaptic Density" — "Protein-rich scaffold that organizes receptors and signaling molecules."; "Mitochondrion" — "Provides ATP needed for synaptic transmission and recycling."; "Reuptake Transporter" — "Clears neurotransmitter from the cleft to help end signaling." Distinguish excitatory versus inhibitory synapse by subtle iconography and receptor clustering differences, while keeping biologically accurate neuronal anatomy and proportions. Include clear comparison cues such as small headings above each side reading "Excitatory Synapse" and "Inhibitory Synapse". Visual style: colorful kids-book simplified shapes combined with medical-professional accuracy, cool clinical blues palette with cyan, teal, navy, and soft lavender accents, calm educational mood, high readability, crisp typography, sharp labels, balanced white background, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. No depiction of gore, blood, surgery, cruelty, or real patient photos. 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.
