The reflex is an automatic response to a stimulus that does not receive or need conscious thought as it occurs through a reflex arc. Reflex arcs act on an impulse before that impulse reaches the brain. [1] Reflex arcs can be. Monosynaptic i.e., contain only two neurons, a sensory and a motor neuron.
The response can be any action that helps the organism to avoid the harmful situation. Reflex actions allow us to respond to dangerous situations rapidly and automatically. Reflex actions do not involve conscious thought. The nervous system responds to stimuli (events or things) via a reflex arc. Some examples of reflexes are:
Reflexes can be spinal or cranial, depending on the nerves and central components that are involved. The body uses both spinal and cranial reflexes to rapidly respond to important stimuli. All reflex arcs include five basic components; (1) a receptor, (2) a sensory neuron, (3) an integration center, (4) a motor neuron, and (5) an effector.
May 19, 2024 · Some reflex arcs involve only three neurons: a sensory neuron, an interneuron, and a motor neuron. In these cases, the sensory neuron carries the signal from the receptor to the interneuron, which then relays the signal to the motor neuron, resulting in the reflexive response. Examples of reflex actions are numerous and diverse.

Quick, automatic, protective. Reflexes are quick and automatic. They often help an organism respond quickly to a harmful stimulus, e.g. heat. The information is not processed in the brain and no decision is made about the response.
