The Nervous System flashcards are study tools that help students learn about the brain and how it controls the body. These flashcards have been used for many years to help people understand the complex network of nerves and cells that make up the nervous system.
Studying the Nervous System is important because it helps us understand how our bodies work and how our brains control everything we do. By learning about the nervous system, we can better understand how to take care of our bodies and how to keep our brains healthy.

quick facts
- The nervous system is made up of the brain, spinal cord, and nerves.
- Neurons are the cells that make up the nervous system and help transmit messages throughout the body.
- The brain is the control center of the nervous system and is responsible for processing information and sending signals to the rest of the body.
- The spinal cord acts as a pathway for messages to travel between the brain and the rest of the body.
- The nervous system is divided into two main parts: the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves throughout the body).

Front | Back |
---|---|
Neuron | Neuron: A nerve cell that transmits information in the brain and nervous system. |
Central nervous system | The central nervous system is the main control center of the body, including the brain and spinal cord. |
Peripheral nervous system | The peripheral nervous system is the network of nerves that connect the brain and spinal cord to the rest of the body. |
Spinal cord | The main pathway for messages between the brain and the rest of the body. |
Brain | The brain is the control center of the body, responsible for thinking, feeling, and controlling movement. |
Cerebellum | The cerebellum is the part of the brain that helps with coordination and balance. |
Cerebral cortex | The outer layer of the brain responsible for thinking, feeling, and voluntary movement. |
Axon | The axon is a long, slender projection of a nerve cell that carries electrical signals away from the cell body. |
Dendrite | A dendrite is a branch-like structure on a nerve cell that receives information from other cells. |
Synapse | A synapse is a small gap between two nerve cells where they communicate with each other. |
Neurotransmitter | Chemical messenger that transmits signals between neurons in the brain and nervous system. |
Nerve impulse | Signal that travels along a nerve cell. |
Myelin sheath | Protective covering around nerve cells that helps speed up electrical signals. |
Reflex | Reflex: A quick automatic response to a stimulus without needing to think about it. |
Autonomic nervous system | Controls involuntary actions in the body. |
Sympathetic nervous system | Part of the nervous system that controls the body’s fight or flight response. |
Parasympathetic nervous system | The part of the nervous system that helps the body relax and rest. |
Fight or flight response | The body’s automatic reaction to danger, where it prepares to either fight or run away. |
Brainstem | The brainstem is the part of the brain that connects the brain to the spinal cord and controls basic functions like breathing and heart rate. |
Medulla oblongata | The medulla oblongata controls vital functions like breathing and heart rate. |
