This is a neuron labeled blue for tubulin, green for F-actin, and red for presynaptic protein.  Basically, these are all structural parts of a neuron that create its location in space and in relation to other neurons.  Tubulin makes up microtubules.  Microtubules and actin are the main components of the cytoskeleton (cell skeleton- does the same thing for cells as your bones do for you).  Presynaptic proteins are located at the synapses with other cells and serve a variety of functions- here, you can see how many synapses this neuron has with other neurons by the clusters or spots of ‘red’.

There’s just something about this picture that gets to me. How amazing that something like that is working inside our bodies. Quite entrancing…
