The difference between reflex and voluntary action is that a reflex occurs naturally in response to some sort of stimulus and voluntary action is something that is consciously carried out. An example of a reflex action is gagging and an example of voluntary action is flinching when someone is going to hit you.
Voluntary actions are consciously controlled movements initiated by the brain, while reflex actions are automatic responses to stimuli that do not require conscious thought. Voluntary actions involve higher brain functions and can be modified based on individual intent, while reflex actions are typically quick, involuntary responses for immediate protection or survival.
The difference between a reflex and a voluntary muscle is simply that a reflex is autonomic response to a stimulus thus making it involuntary. This in direct contradiction to a voluntary muscle movement with is done by making the conscious decision to do so.
A reflex
Conscious action is a voluntary action that is controlled by the brain and involves awareness and decision-making, such as raising your hand. Reflex action is an involuntary action that is controlled by the spinal cord and occurs without conscious thought, such as quickly pulling your hand away from a hot surface.
Both require motor neurones to carry the nerve impulse to the effector in order for the muscle to contract carry out an action.

No, it is by definition involuntary. The neural impulses which cause the action do not go through the brain at all.
Pupils reacts to light, narrowing in bright light and widening in poor light - so is a reflex action.
Conscious action is a voluntary action that is initiated and controlled by our conscious thoughts and decisions, while reflex action is an involuntary and automatic response to a stimulus that involves a specific neural pathway without requiring conscious thought. Conscious actions are typically intentional and involve higher levels of cognitive processing, whereas reflex actions are rapid and predictable responses designed to protect the body from harm.
The difference between a reflex and a feedback mechanism is that the former is done without action by the brain but the latter is consciously done with feedback from the brain. A reflex is the reaction to external stimuli. Feedback to the brain can be given due to external or internal (within the body) reason.
A conditioned reflex is learned through association, such as Pavlov's dogs salivating at the sound of a bell paired with food. In contrast, an unconditioned reflex is an innate, automatic response to a stimulus without prior learning, like blinking when something comes close to your eye.
An involuntary action is a body process that occurs automatically regardless of external stimulus. In contrast, a reflex is an automated response to an external stimulus.
