Neurons 1
Signals from the environment that activate neurons.
Stimuli
Nerve cells that send and receive messages throughout the body.
Neurons
What is the system that serves as the body's command center?
What parts of the body does this include?
The Central Nervous System, which includes the brain and the spinal cord.
The part of the brain that controls the spinal cord and many involuntary activities, like breathing and heart rate.
Medulla
A word that describes the reaction to stimuli.
Response
The receiving neuron recognizes and processes the message.
Receptor sites
The long, thin fiber of a neuron that transmits signals to other neurons.
Axon
What is the system that serves as the informational highway?
Where do these nerves transmit information from and to?
The Peripheral Nervous System transmits electrical signals from all over the body to the central nervous system.
The part of the brain that controls voluntary movements, the senses, and thought.
Cerebrum
Type of stimuli by smell and taste.
Chemical
Finger-like structures of a neuron that receive electrical signals.
Dendrite
A wave of electrical activity transmitted between neurons.
Nerve impulse
Your heart rate increases during a stressful situation. This part of the nervous system releases hormones, such as adrenaline, which increase heart rate and blood flow.
Hint: an involuntary movement
the Peripheral Nervous System
The part of the brain that keeps the body in balance.
Cerebellum
Type of stimuli by touch, pressure, and sound.
Mechanical
The places where neurons connect and communicate with each other.
Synapse
An involuntary response to an outside stimulus.
Withdrawal reflex
A person suffers a head injury, resulting in a concussion. What part of the nervous system would this affect?
The Central Nervous System
This part of the brain is necessary during a ballerina's performance.
Cerebellum
Type stimulated by light
Electromagnetic
Nerves that transmit signals to skeletal muscle, causing movement.
Motor nerves
Nerves that receive sensory stimuli, such as how something feels.
Sensory nerves
You decide to pick up a can of soda. What part(s) of the nervous system would this involve?
The central nervous system and the peripheral nervous system.
Your blood pressure involves what part of the brain?
Medulla
Chole has just started playing the violin and asked her mom to listen to her play.
Which stimuli is being activated by this environment?
Mechanical
