Description
In order to swim, it is not enough for jellyfish to have only muscles. They also need nerve cells that instruct the muscles to contract. It is often believed that the nervous system of jellyfish is a simple neural network of individual cells. But that's also not true. Jellyfish have complex sensory organs (eyes and organs of balance) and clusters of nerve cells - nerve nodes. You could even say they have a brain. It just doesn't look like the brain of most animals in the head. Jellyfish do not have a head and their brain is a nerve circle with nerve nodes at the edge of the umbrella. From this ring leave the processes of nerve cells, which issue commands to the muscles. Among the cells of the nerve ring are amazing cells - pacemakers. At regular intervals, an electrical signal (nerve impulse) is generated in them without external influence. Then this signal spreads through the ring, is transmitted to the muscles and the jellyfish pulls down the umbrella. If these cells are removed or destroyed, the umbrella will stop shrinking. Man has similar cells in his heart.
