"Central nervous system" Quotes from Famous Books
 ... the arrangement is more complex. There are first the protovertebral rings of the dermatoskeleton, these being principally the ribs, limb-girdles, and jaws. Round the central nervous system are developed the deutovertebral rings of the neuroskeleton (vertebrae in the ordinary sense). The apophyses and bodies of the vertebrae, and the bones of the members[160] are composed of columns of tritovertebrae, or vertebrae ...

... the knowledge we have gained of the electrical and chemical phenomena of the central nervous system, we must confess that we know little indeed of the inner nature of the psycho-physical processes. What is happening in the brain—especially in the psycho-motor centres—when we move an arm by means of an act of will? What are the forms of nervous energy which are employed? Are these entirely electrical ...

... upper arm. The aetiology of spasmophilia is still a matter for dispute, but the evidence which we possess is in favour of the view that we have here to deal with a disturbance of calcium metabolism. The calcium content both of the blood and of the central nervous system has been shown to be much lowered. It is in keeping with this that clinically we note how frequently spasmophilia and rickets occur in the same child. In some families the ...

... functions; in a word, of all the various functions which constitute the proper object of psychology. Modern anatomy and physiology have proved that these psychic functions are immediately dependent on the fine structure and the composition of the central nervous system, or the internal texture of the brain and spinal cord. In these we find the elaborate cell-machinery, of which the psychic or soul-life is the physiological function. It is so intricate that most men still look upon the mind as something supernatural that ...

... peripheral nervous system as the tactual, it produces the same amplitude and perhaps the same form of wave, but the reaction times for the two stimuli differ because of the biological significance of the stimuli. The chances are that this is wholly dependent upon the central nervous system. ...

... transmission of energy from the mother to the foetus by means of the close relation between the maternal and foetal circulation. It is only when the free existence demands activities not necessary in intra-uterine life that existence without a central nervous system ...

... follow the same law as in the adult. They diffuse more widely in the fetus. In the adult the liver is the chief accumulatory organ. Arsenic, which in the mother elects to accumulate in the liver, is in the fetus stored up in the skin; copper accumulates in the fetal liver, central nervous system, and sometimes in the skin; lead which is found specially in the maternal liver, but also in the skin, has been observed in the skin, liver, nervous centers, and elsewhere in the fetus. The frequent presence of poisons in the fetal skin demonstrates its physiologic ...
