What is reflex action explain with example?
(a) Reflex action is a rapid and automatic response to a stimulus. It is not under the voluntary control of the brain. For example, if we unknowingly touch a hot plate, we immediately move our hand away from it. (b) The path travelled by an impulse during a reflex action is called a reflex arc.
What is reflex action explain?
In biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action and nearly instantaneous movement in response to a stimulus. The reflex is then an automatic response to a stimulus that does not receive or need conscious thought.
What is the best description of a reflex action?
A reflex action, also known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus.
What is reflex action describe the steps involved in a reflex action?
A reflex action involves following steps: Stimulus → Receptor organ → Afferent nerve fibre → Central Nervous system (spinal cord) → Efferent nerve fibre → Effector organ → Response. Additional information: – Nerves from various parts of the body bundle up in the spinal cord before they enter the brain.
What is a reflex action explain it with a diagram?
A reflex arc is a simple nervous pathway which is responsible for the sudden reaction known as the reflex action. The afferent/sensory neurons are present in the receptor organ which receive the stimulus. The neuron transmits the sensory information from receptor organ to the spinal cord.
What is reflex action give two examples?
Reflex action is defined as an unconscious and involuntary response of effectors to a stimulus. Example, on touching a hot object (stimulus), we immediately remove our hand from it. Other example from daily life are watering of mouth on seeing food, sneezing, blinking of eyes and yawning.

A reflex action is a spontaneous ,automatic and mechanical response to stimulus or sudden action in response to something in the environment. For Ex:Blinking of eyes, movement of diaphragm, withdrawal of hand or foot every time when a needle or hot object is touched, sneezing, hunger etc.
What are reflex actions give 4 examples?
List Down 10 Examples of Reflex Action
- Closing of eyes when a bright light hits our eyes.
- Sudden withdrawing hands or legs when they touch something hot or pricking.
- Coughing or sneezing due to irritants in the nasal passage.
- Batting of eyelids frequently.
- Blinking eyes when insects come in contact.
- Rooting reflex in infants.
What are the 5 steps of reflex action?
So the reflex arc consists of these five steps in order-sensor, sensory neuron, control center, motor neuron, and muscle. These five parts work as a relay team to take information up from the sensor to the spinal cord or brain and back down to the muscles.

What are some examples of a reflex action?
Examples of reflex actions Sneezing and coughing Knee-jerk reflex Pupil reflex Sweating Jerk occurs by touching a hot or sharp object Reflexes take place by seeing an object suddenly coming to you
What are the advantages of a reflex action?
Animals defend themselves from adverse conditions without any delay.
What are the different types of reflex actions?
Accommodation reflex: The most common reflex of eyes, that helps the pupils, lens and vergence change the shape to accommodate of sight, when we look at distance object and near Pupillary light reflex: If a light is flashed near one eye, the pupils of both eyes contract. Acoustic Reflex: The word acoustic might ring a bell in your ears?
