Nervous System
Name the two divisions of the Nervous System
What is the central nervous system (CNS) and peripheral nervous system (PNS)?
carries information from one neuron to another
What is an interneuron?
The number of neurons the human body has.
What is 100 million-100 billion?
What is an action potential?
There are five of these in your brain
What is a lobe?
Contains a network of nerves that branch out of your Central Nervous System
What is the peripheral nervous system?
sends nerve impulse to muscle or gland
What is motor neuron?
The number of miles of nerves in your body.
Electrical impulses move in this direction.
What is from dendrite to axon?
What is the largest part of the brain?
What is the cerebrum?
In charge of voluntary actions
What is the somatic nervous system?
picks up stimuli from the external and internal environment
What is sensory neuron?
the percentage of neurons are in the cererbum
What is 75%?
The space between the axon and dendrite.
What is a synapse?
This lobe of the brain is still forming in teenagers
What is the frontal lobe?
in charge of involuntary actions
What is the automatic nervous system?
carries information towards neurons cellular body
What is dendrite?
The percentage of the brain that is water.
What is 75 percent?
This carries neurotransmitters, or messages, and causes the axon to open up small holes which allow the neurotransmitters to leave the axon and enter the synapse.
What is a vesicle?
The weight of the adult brain.
What is 3 pounds?
the five functions of the nervous system
What are motor, sensory, automatic, cognition, emotions, and consciousness?
carries nerve impulses away from the cellular body of the neuron
What is an axon?
Number of nerves in the human body
What is 7 trillion?
*DOUBLE JEOPDARY*
In your own words, explain how neurons pass an electrical signal or message?
responses will vary
The part of the brain that stores memories and emotions
What is hippocampus?
