Reflex Unconditioned

Unconditioned reflexes are elementary defense mechanisms of the body that do not require complex learning processes. No matter what happens, these defensive reactions always proceed the same way and to the fullest extent. It is customary to talk about unconditioned reflexes in relation to those movements that a person can make while still in the womb. The unconditioned reactions include the following movements: sucking, grasping and unclenching the mouth; withdrawing the hand in case of danger; certain swallowing reactions; attempts to hold the breath of children when liquid gets into the nose. In addition, unconditioned reflexes consist of certain protective postures adopted by the body, such as closing the eyes in bright light. Unconditioned reactions ensure the integrity of the body and its adaptation to the environment. The receptors responsible for the manifestation of reactions are located in the brain or internal organs. If changes occur in the internal environment, then a reflex response occurs immediately. The most important unconditioned reflex is the vasomotor reflex, which regulates body temperature. The pathways that provide this reflex are the neural arc of vasomotor reflexes. Motor impulses arise in the area of ​​the spinal cord and brain, and then are sent to the cranial cavity and ear artery
