"Endocrine System" - A decrease in the level of calcium in the blood reduces the excitability of the central nervous system. Digestive and endocrine glands. The cortical substance includes: the glomerular bundle and reticular zones. Hydrophilic hormones. The mixed glands include: Structure: 1) Head 5) Tail 6) Body. Thymus (thymus gland).

"The structure and function of the kidneys" - The disease is called diabetes insipidus. Urination consists of three processes: filtration, reabsorption, tubular secretion. The sun is represented by the kidneys, ureters, bladder, urethra. What are the three processes in the kidneys? In the nephron, a Bowman-Shumlyansky capsule is distinguished, in which there is a capillary glomerulus.

"Structure of the nervous system" - The functions of the somatic nervous system are controlled by our consciousness. The autonomic nervous system. The structure and function of the spinal cord. The structure and significance of the nervous system. Peripheral nervous system (nerves and ganglia). The functions are similar: reflex and conductive. Unconditioned reflexes of the brain.

"The organ of hearing and balance" - A person is able to hear sound in the range from 16 Hz to 20 kHz. From which ear there are more correctly recognized words, then the leader. It is possible to determine the leading ear using special tests. Inner ear. The function is to catch sounds and transmit them to further parts of the organ. Middle ear. Outer ear. Currently, miniature BTE hearing aids are gaining in popularity.

"Nervous system" - The cerebellum is also well developed and has convolutions. The diencephalon and cerebellum are well developed. The nervous system of amphibians is characterized by a more complex structure. A relationship was established between the number of convolutions and the complexity of the mammalian behavior. The olfactory lobes are small. The midbrain is well developed. The medulla oblongata passes into the dorsal (Fig. 176).

Sleep and its meaning. Sleep (Latin somnus) is a natural physiological process of being in a state with a minimum level of brain activity and a reduced response to the world around it, inherent in mammals, birds, fish and some other animals, including insects (for example, fruit flies). During sleep, the work of the brain is rebuilt, the rhythmic work of neurons resumes, and strength is restored. SLEEP Slow phase Fast phaseFill in the table (textbook, page 222) Slow sleep REM sleep Heart beats slower; Metabolism is lowered; Eyeballs under the eyelids are motionless. The work of the heart intensifies; The eyeballs begin to move under the eyelids; Hands are clenched into fists; Sometimes the sleeping person changes posture In this phase, dreams come. The names of the sleep phases are associated with the biocurrents of the brain, which are recorded on a special device - an electroencephalograph. During slow sleep, the device detects rare waves of large amplitude. In REM sleep, the curve drawn by the device registers frequent fluctuations of small amplitude. Dreams. All people have dreams, but not everyone remembers them and can tell about them. This is due to the fact that the work of the brain does not stop. During sleep, the information received during the daytime is organized. This explains the facts when problems are solved in a dream that could not be solved in a state of wakefulness. Usually, a person dreams of something that worries him, worries, worries. The state of anxiety leaves its imprint on dreams: they can cause nightmares. Sometimes it is associated with physical and mental illness. Usually, disturbing dreams stop after a person recovers or their experiences end. In healthy people, dreams are often calming. The meaning of sleep: draw a conclusion and write it down in a notebook, Sleep provides the body with rest. Sleep promotes the processing and storage of information. Sleep (especially slow sleep) facilitates the consolidation of the studied material, REM sleep implements subconscious models of expected events. Sleep is the body's adaptation to changes in illumination (day-night). Sleep restores immunity by activating T-lymphocytes that fight colds and viral diseases. the central nervous system analyzes and regulates the work of internal organs. The need for sleep is as natural as hunger and thirst. If you go to bed at the same time, repeat the ritual of going to bed, then a conditioned reflex reaction is developed and sleep comes very quickly. Sleep and wakefulness disturbances can have negative consequences. Before going to bed, it is useful to: * take a walk in the fresh air; * have dinner 1.5 hours before bedtime, eat light, well-digestible food; * the bed should be comfortable (it is harmful to sleep on a too soft mattress and a high pillow); * ventilate the room, sleep with the window open; * brush your teeth and wash your face immediately before going to bed.Long sleep is just as harmful as prolonged wakefulness. It is impossible to stock up on sleep for future use. Homework paragraph 59, learn the basic concepts, make a memo "The rules of healthy sleep."
