This grayscale electron micrograph shows a close-up view of neurons (nerve cells). The image depicts several neuron cell bodies and their surrounding structures. The cell bodies are irregularly shaped and contain visible nuclei (the darker circular regions within the cells). Thin, linear structures represent axons and dendrites - the processes that extend from the cell body to communicate with other neurons. The background is a dense matrix of cellular components. The image's high magnification detail shows the complexity of neuronal morphology.
