Which system includes the brain and nerves?

• A. Musculoskeletal system
• B. Endocrine system
• C. Nervous system
• D. Lympho-reticular system

Answer: (C)

The brain and nerves are part of the nervous system, the body's rapid communication and control network. Neurons transmit electrical signals that coordinate thoughts, senses, reflexes, and movements, with the brain acting as the control center and nerves carrying messages to muscles and organs. The musculoskeletal system involves bones, muscles, and joints for movement but doesn’t include brain or nerves. The endocrine system uses glands and hormones to regulate processes more slowly, not through direct neural signaling. The lympho-reticular system handles immune functions and fluid balance, not neural communication. So, the nervous system best fits the description.
