What are the differences between reflex action and reflex arc?
Differences between Reflex Action and Reflex Arc:
Reflex Action:
Reflex Arc:
Key Differences:
- Reflex Action: It is an immediate and automatic response to a stimulus that does not involve the conscious part of the brain.
- Reflex Arc: It is the neural pathway that mediates a reflex action, which involves a sensory neuron, an interneuron, and a motor neuron.
Reflex Action:
- Reflex action is a rapid and automatic response to a stimulus that does not require conscious thought or decision-making.
- It is a protective mechanism that helps to avoid harm or injury.
- For example, when a person touches a hot stove, they automatically withdraw their hand to avoid getting burned.
- Reflex actions are controlled by the spinal cord and brainstem, which are located in the lower part of the brain.
Reflex Arc:
- Reflex arc is the neural pathway that mediates a reflex action.
- It involves three types of neurons: sensory neurons, interneurons, and motor neurons.
- The sensory neurons detect the stimulus and send a signal to the spinal cord.
- The interneurons process the signal and send a message to the motor neurons.
- The motor neurons respond by activating the muscles or glands that produce the reflex action.
- The reflex arc is a rapid and automatic process that occurs without conscious thought or decision-making.
- It is a protective mechanism that helps to avoid harm or injury.
Key Differences:

What are the differences between reflex action and reflex arc?
Reflex arc is the neural pathway involved in a reflex action.
A reflex arc usually consists of five elements; receptor, sensory neuron, an integration centre (e.g. an association neuron in the central nervous system; this may be absent in some reflex arcs), a motor neuron, and a muscle that acts as the effector.
A reflex action, also known as a reflex, is an involuntary (often) and instantaneous movement or action in response to a stimulus.
