Parts of the Neuron
Brain
Explain the difference between a sensory and a motor neuron
Sensory Neurons pick up on stimuli and deliver them to the central nervous system (cause)
Motor Neurons deliver messages from the brain to the rest of the body (reaction)
The central nervous system is located in the ______ of your body.
Center
Bundles of neurons come together to create...
Nerves
Something from the outside world that causes our bodies to react.
The nucleus
Sensory neurons work closely with which of the two parts of the nervous system?
-Peripheral
-Central
Peripheral
The central nervous system is made up of....
The brain and the spinal cord
Where can you find the peripheral nervous system (or our nerves)?
All over our body!
When you put your hand on a hot stove, which part of the nervous system is activated FIRST and sends a message using which type of neuron?
Peripheral nervous system, sensory neurons
The circular part of the neuron that protects the nucleus
Cell Body
How quickly do sensory and motor neurons respond to stimuli from the outside world?
Instantly
Which statement best describes the CNS?
1. It includes the brain, spinal cord and all the nerves in the body.
2. It gathers information from the outside world through touch, sight and temperature.
3. It includes the brain and the spinal cord and makes decisions for the body.
4. It helps your body only respond to pain.
3. It includes the brain and the spinal cord and makes decisions for the body.
If the CNS is the effect or reaction, the PNS senses the ________.
Cause
Which of the following is NOT an example of stimuli?
A. Feeling the rain on your skin
B. Seeing a double rainbow
C. Falling asleep after a long day
D. Getting a brain freeze from eating ice cream too fast
C. Falling asleep after a long day
Explain why the axon is like amazon and why the myelin sheath is like amazon prime
Axon - delivers a message from the nucleus to the axon terminal
Myelin Sheath - speeds the message up
When I say sensory you say _______
When I say motor you say ________
Senses
Motion
The central nervous system delivers responses to stimuli from the outside world by sending ______ neurons out to the rest of the body.
Motor Neurons
The peripheral nervous system is like a pathway because the nerves all over our body respond to stimuli by sending signals to the central nervous system.
You are listening to your favorite song and start to sing along. Your sensory neurons deliver the message that your favorite song is on to the ____________ ___________ which then delivers the message to the ___________.
Spinal cord, brain.
Dendrites connect to other neurons by their...
Axon Terminals
Motor neurons tell the body how to react to stimuli
Sensory neurons sensing stimuli and sending a signal through the nerves to the spinal cord and brain
Based on what you have read... How is the spinal cord like a cable?
It carries messages between the brain and the rest of the body.
