Unconditioned reflexes are genetically transferred to the subsequent generation and do not demand conditional production. These are the vital reflexes, they are subdivided into sexual, food, protective and other. The most difficult reactions in which the emotional sphere is involved are called instincts.
Instruction
1. Unconditioned reflexes essentially differ from conditional in the fact that they congenital, are shown at all representatives of a concrete look and often remain throughout all life. Implementation of these reflexes happens through a reflex arch which regulation is assigned to a spinal cord or a stem part of a brain.
2. Congenital reflexes cause organism life, so, thanks to food unconditioned reflexes the newborn looks for food i.e. if to run to the child over a cheek a finger, it will open a mouth and to try to turn the head. When the kid finds a nipple, at it the sosatelny reflex, and afterwards - and glotatelny works. Digestive system works thanks to unconditioned reflexes too, intestines of the newborn are not required to be trained in a vermicular movement, absorption, defecation, etc. At the level of unconditioned reflexes there is a salivation, secretion of gastric juice, release of bile.
3. Big group of unconditioned reflexes – sexual. Thanks to these congenital features there is a reproduction. Process of an erection, ejaculation happens at the level of unconditioned reflexes. By means of congenital reflexes the advance of the impregnated ovum in a uterus and its introduction in endometrium, change of a hormonal background is carried out. At animals the sexual reflexes are shown by "tournament fights", mating dance, pairings, etc.
4. Protective unconditioned reflexes are directed to preservation of life and health of an organism. If the mote gets into an eye - there are frequent blinkings and dacryagogue, at hit of foreign matters (pollen, crumbs) in a nose and a rotoglotka - sneezing is provoked. All this manifestations of protective reflexes. At a congestion of the secret produced at inflammatory process in tracheas or bronchial tubes, the organism by means of cough tries to get rid of slime is manifestation of congenital features too. At poisoning the organism is protected from absorption of toxic substances by vomiting. And here to draw aside a hand from hot or to be covered from the flying subject is the already acquired protective reflexes so the kid will pull a hand to the iron, will not burn yet.
5. In variety of unconditioned reflexes approximate are allocated. Thanks to these reflexes the animals listen and prick up the ears at emergence of danger, sharply turn the head in the direction of a sound source.
6. Carry unconditioned reflexes of self-development to the most difficult instinctive reactions. Submitting to instincts, animals look for new territories for life, overcoming various barriers.
