Question

What is a natural reflex?

Answer 1

Hint: A stimulus that is not subjected to or requires conscious consideration. In biology, a reflex is a series of very simple behavioural segments that usually occur as direct and instantaneous responses to stimuli that are uniquely connected with them.

Complete solution :-
A reflex is an involuntary reaction to a stimulus that does not require or receive conscious cognition. Involuntary and practically immediate movement in reaction to a stimulus is known as reflex action.
A natural reflex is one that does not require any prior knowledge or experience. These reflexes are inborn, meaning they are passed down from one generation to the next.
Blinking, coughing, and sneezing are examples of defensive reflexes.
Functional efficiency is provided by salivation, swallowing, and peristalsis.
Eye pupil dilation to see in the dark and vice versa. It's a muscular motion.
Getting swallowed food to move through the food canal.
It's a muscular motion. Conditioned Reflex: This is a reflex that develops over time as a result of experience or learning. Here are several examples: 1. Mouthwatering (Salvination) at the sight of delectable food 2. Watching TV while surfing the channels on the television screen 3. Using a computer keyboard to type. 4. Being able to play a musical instrument.A reflex, also known as a reflex action, is an unintentional, unplanned sequence of action or movement that occurs in reaction to a stimulus.

Additional information:
Invertebrates' sensory neurons synapse in the spinal cord rather than passing directly into the brain. The spinal cord is the primary control centre for reflex actions.
Babies are hardwired to respond to various cues in their environments with specific, automatic reflexes, from rooting to clutching. Stroke a newborn's cheek, for example, and they'll open their mouth and turn their head to the side that was stroked. Stroke the roof of their mouth and they'll begin sucking.

Note :-
Blinking eyes due to strong light is not natural reflex action, The animal's behaviour is no longer constrained by innate reaction arcs, but can be influenced by experience and exposure to an infinite number of stimuli. The reflexes or involuntary actions that infants perform demonstrate the incredible strength of human instinct and evolution.
