19th-century pregnant dolls

In the 18th and 19th centuries, sideshow carnivals known as misemono were a popular form of entertainment for the sophisticated residents of Edo (present-day Tokyo). The sideshows featured a myriad of educational and entertaining attractions designed to evoke a sense of wonder and satisfy a deep curiosity for the mysteries of life. One popular attraction was the pregnant doll.

This illustration shows a synapse.  When an action potential arrives at a synapse, the positive charge causes the opening of voltage gated calcium channels.  Calcium pours into the synaptic button and binds to several proteins, changing their shape.  The activated proteins dynamically rearrange the blue cytoskeleton to transport green vesicles filled with yellow neurotransmitters to the synaptic cleft, which is filled with red adhesion proteins.  Calcium-activated SNARE proteins bind to both the vesicle and the synaptic membrane, causing the vesicle to fuse with the membrane, turning it inside out and spilling neurotransmitters into the synaptic cleft.  The neurotransmitters then bind to proteins on the receiving cell.  There are several types of yellow-green receptor proteins.  Sodium (Na+) channels (excitatory) respond the the neurotransmitter Glutamate.  Chloride (Cl-) channels (inhibitory) respond to the neurotransmitter GABA.  Dopamine, Serotonin, and Opioids bind to G-Protein Coupled Receptors (GPCRs) which cause complicated phosphorylation cascades that change the metabolism of the cell.
