How are involuntary actions and reflex actions different from each other

Involuntry acitons are not controlled by us they are independent process means therer is no stimulus involved in these actions but reflex action is also involumtary in nature but they involves stinulus measns funcitons or respond according to it. For example involumtary actions heart beat breathing process, etc Reflex actoins, stepping out in bright light, changes in size of pupil of eyes.

Hint:Involuntary action is the collection of muscle activity that does not require planning. But, for one, it is regulated by the brain. While, on the other hand, in response to any stimuli that does not involve the brain is a reflex action which is quick and spontaneous movement. Complete answer: First we should know about the muscle movement to answer this question. The peripheral nervous system's efferent leg is able to communicate signals to the muscles and glands, and eventually essential for voluntary action. In response to voluntary and autonomic (involuntary) brain signals, nerves move muscles. Involuntary actions:- -It is a series of muscle movements that we have no control over. -The brain regulates that behavior. -Throughout one's life, these acts are carried out. -This action can be rapid or slow For eg, contractions of our digestive tract muscles, the heart beat, etc. Reflex Action:- -It is a sudden action that is generated in response to the stimuli, spontaneous and involuntary. -The spinal cord controls it. - These activities were carried out in response to an emergency incident. -This action usually takes place immediately. Remove a hand with a shake, for example, anytime someone touches a hot item. Note:Nerves in animals that regulate skeletal muscles lead to neuron classes throughout the cerebral cortex of the brain’s main motor cortex. Until being conveyed through the pyramidal tract to the spinal cord and then to the motor end plate at the muscles, inst...

The reflex actions are fast automatic, involuntary actions. They are involuntary because they are not ip our conscious control. Reflex actions are response of our body to external stimuli. These stimuli may be light (constriction of pupil of eye), chemicals (sneezing), etc. Involuntary actions are continuous involuntary response of our body to internal stimuli. When food reaches our stomach gastric juice is secreted, without any conscious process. Breathing, beating of heart are all involuntary actions. Involuntary actions are controlled by autonomic nervous system. (It must be kept in mind that for all muscular actions stimuli are must. Muscles contract only when they are stimulated). Reflex action often involves voluntary muscles as effector organ while involuntary actions involve involuntary muscles.

What is Reflex Action? Reflex is an involuntary and sudden response to stimuli. It happens to be an integral component of the famed survival instinct. Most of the common reflexes are a response to all the well-trained, accumulated knowledge of caution that we have internalized. It could be anything and ranges from the reflex action of abruptly withdrawing the hand as it comes in contact with an extremely cold or hot object. This action is termed as the reflex action. It has a subtle relation to instinct. A point to be thought upon is that we all have our instincts differently depending on our past experiences and understanding. A reflex is a reaction triggered by this instinct. At times, we have no prior knowledge if the pan is hot or not. In other words, instinct has little to do with reflex.

It clearly indicates the route adapted when a stimulus occurs and how the reaction takes place. From an evolutionary perspective, reflex action has played an important part in ensuring the survival of organisms as it has enabled quick reactions to certain situations where an organism’s life could be at stake. The Action of Neuron Two neurons dominate the pathway, afferent nerves (receptor) and the efferent Below is a brief description of the events that take place: • Firstly, it begins with receptor detecting the stimulus or a sudde...
