There are many ways to relate a neuron to a tree. For example, the axon sends electrical messages outside the cell body, much like the roots of a tree distribute nutrients throughout the tree.Similar to tree branches gathering nutrition and sunlight, the dendrites receive signals from neighboring neurons.In the same way as a tree trunk connects and supports its branches and roots, the cell body contains the nucleus and supports the neuron.Similar to how tree leaves exchange gasses and release energy, axon terminals release neurotransmitters to neighboring neurons or muscles. In the same way that a tree depends on its branches, trunk, roots, and leaves to flourish, this comparison illustrates how every component of the neuron cooperates to convey messages
I drew an illustration of the brain's three sections: Forebrain, Midbrain, and Hindbrain. Also displaying the many lobes and their roles.
