CNS
What does CNS stand for?
What is the central nervous system?
What does PNS stand for?
What is the Peripheral Nervous System?
What is a neuron?
What is a cell that sends/receives signals in the nervous system?
What does the nervous system help your body do?
What is sense, process, and respond to stimuli?
You touch something hot. What system sends information to your brain?
What is the PNS?
Name the two main parts of the CNS.
What is the brain and spinal cord?
What does the PNS connect to the CNS?
What is nerves outside the brain and spinal cord?
What part of a neuron receives signals?
What is dendrites?
What is a stimulus?
What is A change or piece of information that causes a response?
You hear a loud noise. Is hearing the stimulus or the response?
What is a stimulus?
What is the main job of the brain?
What is Controls and processes information?
What is the main job of the PNS?
What is carries information to and from the CNS?
What is the job of the axon?
What is carries signals along the neuron?
What is a synapse?
What is the gap between neurons where a signal is passed to the next neuron.
Ethan steps on a sharp game piece and quickly lifts his foot. What is his response?
What is lifting his foot and saying ouch?
What is the role of the spinal cord?
What is relays signals from the PNS to the brain and can send responses
Explain how the PNS sends information to the CNS.
What is carries information about the body/environment to the CNS and carries instructions from the CNS back to the body?
What does the myelin sheath do?
What is increases the speed at which signals travel?
Put these in order: response, stimulus, brain processes information, sensory information reaches CNS.
What is Stimulus to sensory information reaches CNS to brain processes information to response.
Lindsey sees a red cardinal, but when she looks back, the bird is gone. What sense did Lindsey use to notice the bird?
What is sight?
Explain how the brain and spinal cord work together.
What is the brain processes information and makes decisions; the spinal cord carries messages between the brain and body.
Compare the CNS and PNS.
What is CNS = brain and spinal cord; PNS = nerves outside the brain and spinal cord that carry messages to and from the CNS
Explain how dendrites, cell body, axon, and synapse work together to send a signal.
What is Dendrites receive signals. Cell body contains the nucleus and controls cell activity. Axon carries the signal. Signal reaches the synapse and can pass to the next neuron.
Describe the path of information when you touch something hot and move your hand away.
What is touch hot object to PNS detects/sends information to spinal cord/CNS processes the information to signal is sent to the body to hand pulls away.
Renzo hears his dog barking, gets up, walks to the door, and lets the dog outside. What was the stimulus and what was the response?
What is
Stimulus: Renzo hears his dog barking.
Response: He gets up, walks to the door, and lets the dog outside.
