All reflex reactions occurring in the body, were divided into two main groups: conditional and unconditional.Conditioned reflexes are acquired by the body on the basis of life experience, they can be produced, fixed or disappear.In some members of the species, they may be others - absent.Unconditional same reflexes handed down from generation to generation, they are common to all members of the species.They are very difficult to influence, they remain constant for life.
conditioned reflexes appear on a variety of stimuli, it may be a certain sound, scent, object, event.For example, the form of a burning candle cause a child crying, if
it is already burned.If you open the refrigerator for a cat will always mean a sausage, then he hears this sound even from another room and immediately wants to eat.It's conditioned reflexes are absent in other children or cats, and even in these specific members of their species may disappear under certain circumstances.
proved that conditioned reflexes are closed at the level of the cerebral cortex, they appear on the basis of unconditional.For example, unconditioned reflex - salivation at the sight and smell of food.A conditional - this is when saliva is allocated to the sound of opening the refrigerator.
as conditional and unconditional reflexes are divided into receptor grounds:
- eksteroretseptivnye when irritated external organs (sight, smell, taste, and so on. D.)
- interoretseptivnye when exposure occurs to the internalauthorities.
on the biological value of the release:
- alimentary reflexes (swallowing, chewing, sucking, saliva, gastric juice and so on. D.
- defensive when the body tries to eliminate the painful stimulus;
- sexual andparental reflections related to procreation;
- locomotor and Article kinetic help to stand, walk and move;
- the preservation of homeostasis in the body - breathing, thermoregulation, heart rate, and so on. d.
- reflex "What's that?" whena rapid fluctuation of the environment body guards, listens.
Typically, the conditioned reflex consists of several components. For example, the dog every day sees teasing her boys. Along with protective movements occur, and other reactions of the body: quickensbreath, hair stands on end, the heart starts to beat faster, she squeals and barks, changing the composition of the blood, etc.
