Answer:
Neurons
Explanation:
Neurons are specialized cells, found in the nervous system, which transmit information.
Neurons contain a dendrite, a soma, and an axon. Some axons are covered with a fatty substance known as the myelin sheath, which surrounds the axon, acting as an insulator and allowing faster transmission of the electrical signal.

Answer:
Your immune system fights off infection and disease. It has a number of ways to detect and destroy anything it recognizes as foreign to your body, including bacteria, viruses, fungi, parasites or unhealthy cells such as cancer cells. In some people, the immune system goes into overdrive, causing the body to see its own cells as foreign and attack them. This leads to what we call autoimmune diseases, such as Crohn’s disease, rheumatoid arthritis and lupus.
Explanation:
Centrioles are paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope. Centrioles play a role in organizing microtubules that serve as the cell's skeletal system. They help determine the locations of the nucleus and other organelles within the cell.
