Diagrama celula: sinapsis neuronal médica en infografía

Biological diagram infographic titled "Neuron Synapse" centered on a clean labeled cross-section of a chemical synapse between a presynaptic axon terminal and a postsynaptic dendritic spine, editorial-grade and biologically accurate for a medical professional audience. Render a minimal flat scientific anatomical illustration with forest green and earth-tone palette, balanced negative space, crisp typography, sharp readable labels, and precise proportions. Show the presynaptic bouton packed with synaptic vesicles, mitochondrion, active zone, and voltage-gated calcium channels; depict the synaptic cleft between membranes; show the postsynaptic membrane with neurotransmitter receptors and a dendritic spine/shaft profile. Arrange exactly 9 labels around the central diagram with thin leader lines, each containing a short heading in quotes and a one-line function caption in quotes. Use medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Labels to include: 1. "Presynaptic terminal" — "Axon ending that stores and releases neurotransmitter." 2. "Synaptic vesicles" — "Membrane sacs that package neurotransmitter for exocytosis." 3. "Active zone" — "Specialized presynaptic membrane where vesicles dock and fuse." 4. "Voltage-gated Ca2+ channels" — "Calcium entry triggers synaptic vesicle fusion." 5. "Mitochondrion" — "Provides ATP for neurotransmission and vesicle recycling." 6. "Synaptic cleft" — "Narrow extracellular gap across which transmitter diffuses." 7. "Postsynaptic membrane" — "Receiving membrane that converts chemical signal to response." 8. "Neurotransmitter receptors" — "Ligand-gated proteins that bind transmitter and open signaling pathways." 9. "Dendritic spine" — "Postsynaptic protrusion that compartmentalizes excitatory input." Include subtle arrows indicating neurotransmitter release from vesicles across the cleft toward receptors, but keep the composition primarily a labeled anatomical cross-section rather than a process flow. Overall mood: calm, precise, professional, educationally tasteful, scientifically rigorous, no gore, no blood, no patient photography, no cruelty imagery, no decorative clutter. 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.
