Question

explain how cells in the nervous system form tissues and organs. Explain an in-beginner 7th grader's words and in 7 sentences.

Answer 1

The nervous system is made mostly of two kinds of cells: neurons, which send messages, and glial cells, which help and protect neurons. Neurons send information using tiny electrical pulses and by releasing chemical signals to other cells. Glial cells give neurons nutrients, clean up waste, and hold them in the right place. Many neurons and glial cells group together and stick to each other to form nervous tissue. That nervous tissue is organized into larger parts like nerves, the spinal cord, and the brain. In the brain, billions of neurons connect into networks that let us think, remember, and control our muscles. During growth, these cells divide, become specialized, and make the correct connections so the tissues and organs work properly.
