伟大的俄国生理学家巴甫洛夫是高级神经活动学说的创造者,这个学说给整个现代医学领域以巨大的影响。条件反射是神经活动的主要形式之一,它保证生活机体能很好地适应於经常在变化着的环境。大家知道,机体和它的各个器官(肌肉、腺体、心、肺等等)的活动,受着神经系的管制和调节。神经系分为中枢神经系和周围神经系。中枢神经系是由脊髓和大脑所构成,脊髓位於椎管内,大脑位於颅内。皮层是大脑的外层,很薄,包着大脑两半球;脊髓和大脑藉神经而连系着所有的肌肉,内脏器官和感觉器官、这些神经构成周围神经系。有些神经是把来自感觉器官的刺激传给脊髓和大脑,这类神经称谓感觉神经;另一些神经是回答刺激的,将中枢神经系的兴奋传向肌内及腺体,这些神经是运动神经和分泌神经。
Pavlov, a great Russian physiologist, is the creator of the theory of advanced neural activity, a doctrine that has a huge impact on the entire field of modern medicine. Conditional reflex is one of the main forms of neural activity, which ensures that the living organism can be well adapted to the changing environment. As we all know, the activities of the body and its various organs (muscles, glands, hearts, lungs, etc.) are regulated and regulated by the nervous system. Nervous system is divided into the central nervous system and peripheral nervous system. The central nervous system consists of the spinal cord and brain, the spinal cord is located in the spinal canal, and the brain is located in the brain. The cortex is the outer layer of the brain, thin, containing the two hemispheres of the brain; the spinal cord and brain by the nerve and connected with all the muscles, organs and sensory organs, these nerves constitute the peripheral nervous system. Some nerves pass sensations from sensory organs to the spinal cord and brain. These nerves are called sensory nerves. Others respond to stimuli and transmit the excitability of the central nervous system to the muscles and glands. These nerves are motor nerves and Secretion of nerves.
