The part of the central nervous system that is located in the skull and controls most functions in the body
What is the brain?
What is a stimulus?
A stimulus is anything that can cause a response in an organism.
An example of a response to a stimulus.
Pulling your hand away from a hot surface
Identify the components of a reflex arc.
sensory neuron, spinal cord, motor neuron
Identify the response..."A squirrel scratches at a flea bite"
A squirrel scratches
Which of the following is NOT a function of the nervous system?

b) Regulating emotions
c) Digesting food
d) Processing sensory information
c) Digesting food
What are the two types of neurons
give the third type of neuron and where you can find it for extra 100
Motor neuron, Sensory neuron
interneurons in the Brain
How do stimuli affect behavior?
Stimuli can trigger reactions or changes in behavior.
How is a response related to a stimulus?
A response is a direct reaction to a stimulus.
Why is a reflex action faster than any other action?
Reflex actions bypass the brain and are processed directly through the spinal cord.
When is your test ?

How do taste and smell work together to enhance flavor?
They both contribute to the perception of flavor; taste detects basic flavors while smell adds complexity.
Central Nervous system consist of two organs .. what are their names
The Brain and the Spinal Cord
what is a non example of stimulus
response , jumping, taking hand away from a hot stove, cover eyes for the bright light
What is the type of the nerve that response traveles/
Motor Neuron
Give an example of a reflex action.
The knee-jerk reaction, The pupil constricts when exposed to bright light, Blinking when something approaches the eye. or similar
You quickly move your head when a baseball is thrown toward your face. You are responding to____________
(what kind of stimulus)
an external stimulus
What is the diference in function between motor neuron and Sensory neuron
sensory neuron send message to the brain, motor neuron send message from the brain to the muscles
The Brain
Explain the difference between external and internal stimuli
External stimuli come from the environment, while internal stimuli arise from within the body, such as hunger or thirst.
Describe the role of the brain in forming a response.
The brain interprets the stimulus and decides the appropriate response based on past experiences and current context.
How do reflex arcs protect the body?
They allow for quick reactions to harmful stimuli, preventing injury.
What type of stimulus is heat?
Thermal Stimuli
A quick response to a stimulus, such as pulling your hand away from a hot surface... this is called ...
Reflex Arc
What role do neurons play in the nervous system?
Neurons transmit signals throughout the body, allowing communication within the nervous system.
How do emotional stimuli affect the body?
They can trigger physiological responses, such as increased heart rate or sweating, laughing or crying.
Describe how the body reacts when you feel fear.
The body may experience a rapid heartbeat, sweating, and heightened awareness (the fight-or-flight response)
Give an example of a reflex action not involving pain.
Blinking when something approaches your eye.
