What is a reflex arc in science?

reflex arc, neurological and sensory mechanism that controls a reflex, an immediate response to a particular stimulus.

What is reflex arc and give example?

The sudden involuntary movement in a voluntary organ; in response to a stimulus; is called reflex action. Examples of reflex action: (a) Moving your hand away from a hot iron plate. (b) Blinking of eyes. Reflex Arc: The path of electrical impulse during a reflex action is called reflex arc.

What is reflex arc Brainly?

A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.

How is reflex arc produced?

An example of the reflex arc is it happens when we accidentally touch something hot. The change in temperature is detected by the receptor first. Then electrical impulses are sent to relay neuron which is located in the spinal cord. Sensory neurons are connected to motor neurons by sensory neurons.

How does a reflex action work?

A reflex action often involves a very simple nervous pathway called a reflex arc. A reflex arc starts off with receptors being excited. They then send signals along a sensory neuron to your spinal cord, where the signals are passed on to a motor neuron. As a result, one of your muscles or glands is stimulated.

What is reflex arc Class 10 Brainly?

Answer: The neural pathways that makes reflex actions possible are called reflex arcs. Explanation: Reflex actions are the involuntary movements that occur as responses to stimulus. All impulses do not reach brain.

Why are reflex arcs important?

The reflex arc is essential in producing a quick involuntary response aimed to prevent injury in an individual.
