What is the role of interneurons in reflex pathways?
  1. To transmit signals from sensory neurons to motor neurons
  2. To amplify the reflex response
  3. To inhibit motor neuron activity
  4. To connect sensory and motor neurons

Questions & Step-by-Step Solutions

What is the role of interneurons in reflex pathways?
  • Step 1: Understand that reflex pathways are the routes that signals travel in the body to produce a quick response.
  • Step 2: Identify that sensory neurons are responsible for detecting stimuli (like touching something hot).
  • Step 3: Recognize that motor neurons are responsible for sending signals to muscles to create a movement (like pulling your hand away).
  • Step 4: Learn that interneurons are special neurons that connect sensory neurons to motor neurons.
  • Step 5: Realize that when a sensory neuron detects a stimulus, it sends a signal to an interneuron.
  • Step 6: Understand that the interneuron processes the information and then sends a signal to the motor neuron.
  • Step 7: Conclude that this connection allows for a quick reflex action without needing to send the signal to the brain first.
