Artwork of a nerve cell of the brain & a synapse
Nerve cell and synapses. Artwork of a nerve cell (neurone) of the brain with a close-up of a synapse. The nerve cell body is at lower right. It has a central nucleus (circle) and axons and dendrites (branching processes). The nerve cell receives impulses (messages) from other nerve cells at junctions called synapses. These synapses occur where the terminal boutons (small, triangular) meet the nerve cell. A close-up of a synapse is in the box at top left. The impulses are passed from the bouton (left) to the receiving cell (right) across the synapses in the form of chemical neurotransmitters (small, blue dots)

EDITORS COMMENTS
This artwork showcases the intricate beauty of a nerve cell and synapse within the brain. The image highlights the complexity of our nervous system, revealing the remarkable structure and function of these vital components. At first glance, we are drawn to the nerve cell body situated at the lower right corner. Its central nucleus stands as a focal point, surrounded by axons and dendrites that branch out like delicate tendrils. These branching processes serve as conduits for receiving impulses or messages from other nerve cells. The true marvel lies in the synapses depicted in exquisite detail within a box at the top left. Here, we witness where terminal boutons – small triangular structures – meet with the nerve cell. It is through these junctions that impulses are transmitted from one cell to another. Zooming in further on this close-up view reveals an awe-inspiring sight: chemical neurotransmitters represented by small blue dots bridging between bouton and receiving cell. These neurotransmitters play a crucial role in transmitting information across synapses, enabling communication between neurons. This artwork not only serves as a testament to human ingenuity but also offers us a glimpse into our own inner workings. It reminds us of both our fragility and resilience, showcasing how every thought, sensation, and movement relies on these microscopic wonders within our brains.
