    OENEUM. isTi:<)i>r(rioy. .T5 of nioaiiiiijr. Ill one sense since living matter is continually iiii- <lci-goin<f katal)()lic changes. It is continually dying. The term Miav he applied to the whole organism or to individual tissues. Somatic Death.—The first occurs when one or more functions of ihf IkkIv are so disturbed that harmonious action of all the func- tions ])ecomes inipo.^sihle. The most convenient sign of somatic death is the cessation of the heart-heat, which, however, is not always the cause of death. The deaih of (lie tiimHes does not necessarily take place with somatic death. The nervous system dies very soon ; the heart lasts longer, the last portion to heat iteing the right auricle. The smooth muscle of the intestines re- mains irritable for three-quarters of an hour, and striated muscle at times for hours. Some of the most ini[)ortaut jjrohlems of general physiology are as yet highly spiculative in character, hut most physiologists be- lieve that as knowledge increases they will all, like the phenomena of lifeless bodies, be explained as the result of the properties of matter and energy working under definite laws. QUESTIONS OX CHAPTER I. Define the term physiology. What are tlie piinciiial divisions of pliy.siology? What is meant by human jihysioloi^y'/ (live the derivation of the term ])hysioh)gy. When were the earliest iihysioloftieal ideas lormed ? Name some of the earliest jihvsiologists. What services did Calen. Harvey, Haller. and Miillei- render?

Are they absolutely characterLstic of living matter? What is the physical basis of life? Describe iirotopiasm. What is the evidence that protoplasm is a fluid? What is the finer structure of jirotoplasm? Why is protoplasm not a chemical term? What substance is always ])resent in i>rotoi>lasm ? What char.icterizes the elements of living matter? What is a cell? What are histological dilferentiation and jiliysiological division of labor ? What evidence is there that dead protoplasm ditl'ers from living?
