重要情報
- 1Your nervous system is a network of organs and cells that transmit signals between different parts of your body. It controls everything you do, from blinking to solving math problems.
- 2The brain is the main control center. It receives information from your senses, processes it, and sends out instructions to your muscles and organs.
- 3The spinal cord is like a super highway that carries messages between the brain and the rest of the body.
- 4Neurons are the special cells that carry these electrical signals. They are the building blocks of your entire nervous system.
- 5You can keep your brain healthy by eating nutritious foods, getting enough sleep, and exercising regularly.
- 6Even your skin helps with sensing! It has special nerve endings that detect touch, pain, and temperature.

キーワード
Nervous System
The biological system responsible for transmitting signals between different parts of the body. It includes the brain, spinal cord, and a vast network of nerves. It controls movement, thought, sensation, and automatic functions like breathing.
Brain
The main organ of the central nervous system, located inside the skull. It processes information from the senses, controls thoughts, emotions, and voluntary movements, and regulates many automatic body functions.
Spinal Cord
A long, thin bundle of nerves that runs from the base of the brain down the back, protected by the spine. It acts as a major pathway for signals traveling between the brain and the rest of the body.
Neuron
A specialized cell that transmits electrical and chemical signals throughout the body. Neurons are the basic units of the nervous system, connecting the brain, spinal cord, and other parts of the body.
Reflex
An automatic, rapid response to a stimulus, such as pulling your hand away from a hot stove. It involves a simple neural pathway that doesn't require conscious thought from the brain.
Senses
The ways your body gathers information about the world around you, including sight, hearing, smell, taste, and touch. These signals are sent to the brain for processing.
