sensory organs
chemical stimuli
How does the amount of alcohol consumed by an individual affect the number of brain cells. Identify the Independent variable
spinal cord
How does the amount of alcohol consumed by an individual affect the number of brain cells. Identify a possible controlled variable
Convert chemical stimuli (molecules) in the air into electrical impulses. They are found in your nose.
How does the amount of alcohol consumed by an individual affect the number of brain cells. Identify the dependent variable
taste receptors
mechanical stimuli
hair receptors
brain
Rods and Cones Receptors
Neurons
touch receptors
electromagnetic stimuli
Convert mechanical stimuli in the form of pain, temperature, and pressure into electrical impulses. They are found in your skin.
Processes the electrical signals sent from each receptor and decides on how to respond to the stimuli by sending an electrical signal to a part of the body and/or committing the electrical signal to memory
Age of the individual drinking alcohol
Convert mechanical sound wave stimuli that travel through the air into electrical impulses. They are found in your ears.
Nerve cells that carry information as tiny electrical signals between the receptors and the brain
Olfactory Receptors
Pathway for neural fibers traveling to and from brain; controls simple reflexes that are not sent to the brain.
Stimuli due to a molecule entering through the mouth for taste or nose for smell
Tongue, eyes, skin, nose, and ears are these
number of brain cells
Convert electromagnetic waves (light) stimuli into electrical impulses. These are found in your eyes.
Stimuli that enters the eye as light
amount of alcohol
Stimuli due to touching something and sound waves
Convert chemical stimuli in the food you eat into electrical impulses. They are found on your tongue.
