How happiness comes to us

Recently, Adagamov published a gif with the caption: "a molecule of the protein kinesin walks along a tubulin tube, dragging an endorphin ball behind it." I decided to describe in more detail what is happening on this gif:

The gif shows not the endorphin itself, but the wall of a bubble filled with endorphin, which was synthesized and packaged into a bubble inside the neuron. The tubulin tube along which the kinesin strides is located inside the neuron process. This bubble moves along the process in the direction from the cell to the end of the process, where the walls of the bubble merge with the walls of the end of the process, and endorphin is released from the neuron. Then endorphin will bind to the receptors of neighboring neurons, after which they will be properly torpedoed! And the chain reaction went.


The top of the figure shows a synapse with the ends of the tubes and neurotransmitters released from the vesicles:





The speed of movement of kinesin is 21 cm / h. But that doesn’t mean that happiness doesn’t come right away. These bubbles accumulate at the end of the process in advance, and endorphin is released as a result of a change in charge on the cell membrane. This charge spreads through a network of interconnected neurons almost instantly - like reposts and likes of pictures with kittens in social networks.
