A rapid automatic response to a stimulus, often referred to as a reflex, is an involuntary and immediate reaction to a specific stimulus without conscious thought. This response is typically mediated by the nervous system and involves a direct pathway known as a reflex arc, which includes sensory neurons, interneurons, and motor neurons. An example of this is the knee-jerk reflex, where tapping the kneecap triggers an automatic leg extension. Reflexes serve to protect the body and facilitate quick reactions to external stimuli.
A reflex action is a fast, automatic response to a stimulus by an effector organ i.e. a muscle.
This process is called a reflex arc. It involves a rapid and involuntary response to a specific stimulus, which bypasses the brain and is coordinated by the spinal cord or peripheral nerves. This allows for quick reactions to potential danger without the need for conscious thought.

An animal's immediate automatic response to an external stimulus will vary depending on the circumstance. When the external environment is stimulated there is a response that is triggered.
An automatic reflex arc is a neural pathway that controls reflex actions in response to a stimulus. It involves sensory neurons detecting the stimulus and sending signals to the spinal cord, which then quickly activates motor neurons to produce a rapid and involuntary response, bypassing conscious control from the brain.
No, a reflex is a rapid, involuntary response to a stimulus. The stimulus is what triggers the reflex reaction in the body.

Automatic involuntary responses vary depending on the stimulus and the system involved. You need to be more specific.

A rapid involuntary response to a stimulus is known as a reflex. Reflexes are automatic reactions that occur without conscious thought, typically involving a simple neural pathway called a reflex arc. For example, when touching a hot surface, the body immediately withdraws the hand to prevent injury, demonstrating this quick response mechanism. Reflexes are essential for survival as they help protect the body from harm.
