23 Questions
What is a reflex action?
An automatic response to a stimulus that doesn't involve the brain
Which component of the reflex arc carries the impulse from the receptor to the spinal cord?
Sensory neuron
Where is the interneuron located in the reflex arc?
Spinal cord
What is the function of the effector in a reflex arc?
Produces the response such as muscle contraction or gland secretion
In what sequence does the impulse travel from receptor to effector in a reflex arc?
Receptor → Sensory Neuron → Interneuron → Motor Neuron → Effector
What is the main function of a reflex action?
To protect the body from harm without brain involvement
Which component of a reflex arc converts a stimulus into an impulse?
Sensory Neuron
During a reflex action, what is the role of the interneuron?
Carries the impulse from the sensory neuron to the motor neuron
What is the function of an effector in a reflex arc?
Produces the response by muscles or glands
