Involuntary muscle action. Examples include the beating of the heart, digestion in the stomach, and reflex actions like blinking or sneezing.
These are examples of reflex actions. Reflex actions are automatic responses by the body to certain stimuli, processed by the spinal cord or brainstem without conscious thought.
Fish do have reflex actions.
One important aspect of reflex action is to help protect us without having to think. Reflex actions are involuntary and quick. They are done to meet an emergency and occur at the level of the spinal cord. Examples include the gag reflex clearing unplanned foreign objects or your eyelid closing when something gets near your eye.
Conscious actions, such as voluntary movements controlled by the brain, are not reflex actions in humans. These actions involve decision-making and higher brain functions, unlike reflex actions which are automatic responses to stimuli.
Reflex actions are not controlled by the brain.

The cerebral cortex is not directly involved in producing reflex actions. Reflex actions are controlled at the spinal cord or lower levels of the brain without involvement of higher brain centers like the cerebral cortex.
In some reflex actions, skeletal muscles contract without the involvement of conscious thought or decision-making processes from the brain. These reflex actions are controlled by the spinal cord and are known as spinal reflexes.
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.
Reflex actions do not require thinking, nor do the actions of involuntary muscles.
Automatic movements are often referred to as reflex actions or reflexes. These are involuntary, quick responses to stimuli that are controlled by the spinal cord without conscious thought. Examples include the knee jerk reflex or blinking in response to a sudden bright light.
