The Basics
How the Brain Works
Nerves
Neurons
Sense of Touch
100
The brain, spinal cord and nerves make up this system.
What is the nervous system?
100
This is the largest, most complex part of the brain.
What is the cerebrum?
100
True or false: messages travel slowly along nerves.
What is false?
100
This is a long extension within a neuron.
What is an axon?
100
We use this to touch and feel things (another word for skin).
What is dermis?
200
This is the most important organ in the nervous system.
What is the brain?
200
This is responsible for balance, movement and coordination.
What is the cerebellum?
200
These transmit messages that our brain sends to our muscles, joints and skin.
What are motor nerves?
200
These are shorter, thin fibers within a neuron.
What are dendrites?
200
This lies between the most outer and inner layer of our skin.
What are nerve endings?
300
This connects the brain to the rest of the body.
What is the spinal cord?
300
This coordinates all the messages going in and out of the brain.
What is the brainstem?
300
These receive messages from the muscles, joints and skin and send them to the brain.
What are sensory nerves?
300
These are electrical signals created to transmit messages.
What are nerve impulses?
300
These detect information about the objects that we touch.
What are nerve endings?
400
These connect the spinal cord to our muscles, joints and skin.
What are nerves?
400
Breathing, digestion and our heartbeat are all considered...
What are involuntary movements?
400
These change light, touch, and sound into neural signals.
What are sensory neurons?
400
This controls the neuron and creates nerve impulses.
What is the cell body?
400
This is the most outer layer of our skin.
What is epidermis?
500
When this receives information, it sends a message to a part of the body to tell it how to react.
What is the brain?
500
This controls our intelligence, memory, personality, emotion, speech and the ability to feel and move.
What is the cerebrum?
500
These nerves cause results in movement or a physical reaction such as sweating.
What are motor nerves?
500
The space between one neuron and another.
What is a synapse?
500
These produce nerve impulses which the sensory nerves transmit to the brain.
