Satellite in biology refers to small cells or structures that are close to or surrounding larger cells or tissue that they depend on for survival. Think of them like little helper cells. Just like how we need our parents to take care of us when we're little, satellites need the larger cells to take care of them.
These satellites can be found in various parts of the body including muscles, nerves, and glands. They help provide support and nutrients to the larger cells and tissue, allowing them to function properly.
Without satellites, these larger cells and tissues may not be able to survive or function as well. It's kind of like how a plant needs the right soil and nutrients to grow.
Scientists are still studying these little helper cells and discovering new things about them every day. But for now, just remember that satellites are important cells that help keep our bodies working properly.
