For those who are curious (simplified definitions): Top left: Dendritic–A specialized white blood cell for immune defense). Middle left: Red blood cells (red discs–oxygen carriers); white blood cells (purple nuclei); platelets (tiny lighter red–blood clotting); lymph nodes (light brown beans arranged like a net–garrison for immune cells; filters for bad stuff). Top right: Epidermal–Type of cell in the top-most layers of your skin. Middle left: Type of tumor cell. Middle middle: Macrophage–A cell that gobbles up the bad stuff in your body. Middle right: Neutrophil (type of white blood cell). Bottom left: Osteoclast–A cell that breaks down bone for remodeling. Bottom middle: Columnar–A special kind of highly absorbent cell lining all body surfaces. Bottom right: Stromal (long skinny tapered)–A cell that physically supports and helps maintain others. Tumor (ovoid with purple nuclei). |
Another word about cells: certain ones resemble others. The dendritic cell from my collage for example can be mistaken for a NEURON, which also has dendrites, or branched arms extending from the cell body. In the lower illustration, I included glial cells to show some structural variations.
The big difference is in function, for a dendritic cell helps to stimulate your immune system cells into action, whereas the neurons are your brain cells.
