Science Sensory Receptors Flashcards
What are human sensory receptors?
They are parts of our body that help us use our senses to gather information about the world around us.
What are the five senses?
The five senses are sight, hearing, touch, taste, and smell. They help us understand our environment.
What is a stimulus?
A stimulus is anything that triggers (starts) our senses.
For example, a sound, a bright light, or a strong smell.
What is a response?
A response is what our body does when it reacts to a stimulus.
For example, jumping when you hear a loud noise.
How do we use our senses?
We use our senses to gather information. Each sense works with receptors to send messages to our brain.
What is the central nervous system?
The central nervous system includes the brain and spinal cord. It helps process the information from our senses.
What happens when sensory input triggers a behavior?
The input starts an action or behavior, which is called a response.
What can we do to test our reaction time?
We can do fun tests online, like seeing how fast we can click when we see a signal!
What is a Receptor?
A receptor is a tiny part of your body that helps you feel, see, hear, or smell things around you and sends that information to your brain.
What is a Response?
A response is how your body reacts to something, like jumping when you hear a loud noise.
What is a Stimulus?
A stimulus is something that causes you to react, like a loud noise or a bright light.
How do Sensory Receptors help animals survive?
Sensory receptors help animals by noticing things around them.
For example, rabbits hear a predator and run away, or birds spot food with their eyes.
What is the Central Nervous System?
The central nervous system is like a messenger highway that helps your brain talk to the rest of your body using the spinal cord.
How does the Brain send messages to the Body?
The brain sends messages through nerves to tell your body what to do, like move your hand if you touch something hot.
What is the job of Sensory Receptors?
Sensory receptors help you notice things around you, so you can stay safe and react quickly.
