What is reflex download?

Reflex for download is an involuntary process that causes part of the body to automatically pull away from something that causes pain. It is also called reflex flexion, it is a three -stage process that includes the nerves strengthening the message to the spinal cord to communicate the muscles in this part of the body to bend and pull away from the source of pain. The primary purpose of this involuntary reaction is to help prevent or minimize injuries. In some cases, for example, when a shoulder or leg is affected, the withdrawal can be a reflection on a reflection of cross expansion to help protect the body better.

Although this may seem simple at first, the reflex of the download actually includes three separate neurological steps. In the first step, pain receptors in the affected area sent the spinal cord. When the message reaches the spinal cord, the interneuron sends a message to the nerves that control the flexor muscles near the affected area. In the third step, these motor neurons call suitable Muscles on Flex, resulting in towing partbodies from everything that causes pain. Since spinal cord is the main area of ​​control in this process, rather than in the brain, the reflex is known as the type of backbone reflex

The main purpose of reflection is to avoid injury or reduce the severity of one. For example, if one touched a prickly bush with a hand, downloading would usually dig down to quickly pull out the hand away to prevent cut or deep piercing of the wound. Or, if a person leaned against a hot object, the body would be pulled away from the object to prevent or minimize burns.

In some cases, for example, when the arm or leg is exposed to pain, the parking reflex may be accompanied by one of the other body reflexes of the spinal cord: a cross extension reflex. This reaction involves a similar three -stage process, but entead interneurons in the spinal cord strengthening the report of motor neuron pain that controls flexors in oBodies that experience pain are sent by neurons that control the extensor muscles in the opposite limb. This limb is then pushed to help reflex with placing injuries, either by pushing the source of pain or providing further support to the body to compensate for the towing of the other limb.

For example, if the left hand of a man was bitten by a dog, both reflexes could cooperate to withdraw the left hand at the same time and use the right hand to push the dog. Or, if one entered the nail with the right leg, the opposite leg would push down, so the person did not fall when his left leg and leg pulled up to withdraw the reflex.
