Shivering from excitement
Drinking coffee to stay awake
Eating food when bored
When body temperature rises, which of the following is a homeostatic response?
Blood vessels constrict
Heart rate slows
Sweat glands become inactive
Sweat glands release sweat
Which part of the neuron receives signals from other cells?
Axon
Cell body
Axon terminal
Dendrites
What is the function of the axon in a neuron?
Insulates the neuron
Stores neurotransmitters
Sends electrical impulses away from the cell body
Receives signals from other neurons
Where are neurotransmitters released from in a neuron?
Dendrites
Axon terminal
Cell body
Nucleus
What type of signal travels within a neuron?
Magnetic
Chemical
Electrical
Optical
How is the signal transmitted between neurons at the synapse?
By hormones
By neurotransmitters
By electric sparks
Through physical contact
Which of the following best describes what happens at a synapse?
Electrical impulses jump directly between neurons
Neurons touch to transfer impulses
Neurotransmitters cross the gap between neurons
The axon fuses with the dendrite of the next neuron
Which neurotransmitter is most associated with feelings of happiness?
Adrenaline
Dopamine
Serotonin
Cortisol
Which neurotransmitter is involved in the ‘fight or flight’ response?
Dopamine
Serotonin
Adrenaline
Oxytocin
Which neurotransmitter plays a key role in motivation and reward?
Dopamine
Serotonin
Acetylcholine
Adrenaline
Which neuron carries messages from sense organs to the spinal cord or brain?
Motor neuron
Relay neuron
Sensory neuron
Reflex neuron
What is the function of a relay neuron?
Carries signals to muscles
Sends messages to the skin
Passes signals between sensory and motor neurons
Sends signals from muscles to the brain
Why is a reflex arc important?
It slows down responses to pain
It ensures conscious thought is involved
It allows quick responses to protect the body
It helps maintain blood pressure
