No, it is by definition involuntary. The neural impulses which cause the action do not go through the brain at all.
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.
A reflex
Pupils reacts to light, narrowing in bright light and widening in poor light - so is a reflex action.
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 not a reflex action
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.
AnswerBecause a reflex action is automatic and does not involve a thought process.Edit: A reflex action only has to go to the spinal cord and then back to the limb, whereas a voluntary reaction has to go to the brain to be processed and therefore takes longer.
No, it is a reflex. More specifically it is known as a flexion reflex.
The patellar reflex is inhibited
Voluntary Act
Blinking is a reflex, not a habit, conditional response, trial and error learning, or instinct. It is a protective response that helps keep the eyes moist and free from debris by closing and reopening quickly.
