Question: What is the role of interneurons in a reflex arc?

Options:

  1. To transmit signals to the brain
  2. To connect sensory and motor neurons
  3. To inhibit reflex actions
  4. To enhance muscle contraction

Correct Answer: To connect sensory and motor neurons

Solution: 

Interneurons connect sensory and motor neurons within the spinal cord, facilitating the reflex response.

Questions & Step-by-Step Solutions

What is the role of interneurons in a reflex arc?
  • Step 1: Understand that a reflex arc is a pathway that controls a reflex action.
  • Step 2: Identify the three main types of neurons involved: sensory neurons, interneurons, and motor neurons.
  • Step 3: Recognize that sensory neurons carry signals from the body to the spinal cord when a stimulus is detected.
  • Step 4: Learn that interneurons are located in the spinal cord and act as connectors.
  • Step 5: Understand that interneurons receive signals from sensory neurons and then send signals to motor neurons.
  • Step 6: Realize that motor neurons carry signals from the spinal cord to muscles, causing a reflex action.
