The earliest blood-vessels in man

Blood vessels of the ciliary ganglion in man.

Blood vessels of the bulbar conjunctiva in man.

LARGELY owing to technical difficulties the role of the capillary in human disease is not known. Chambers (1948) stated that an adequate survey of the capillary bed for study of the variations in its functional activity required tissue in which the vessels could be traced from the arteriolar to the venular ends, and at the same time be exposed for observation with a minimum of trauma so as not ...

the tragedy of modern man in arthur millers world

what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...

Pressure-radius relationship in large blood vessels of man.

• The measurement of instantaneous blood flow in the great vessels in man is of importance in the study of circulatory dynamics. With the pressure-gradient technique, it is possible to estimate instantaneous blood velocity in man. However, in order to compute instantaneous blood flow from blood velocity, the radius of the vessel under study must be known at every instant in the cardiac cycle. T...

PRE- AND POSTJUNCTIONAL α-ADRENOCEPTORS IN RABBIT ARTICULAR BLOOD VESSELS

Previous in vitro work on rabbit knee joint vessels showed that vasoconstrictor effects of nerve stimulation and administration of α-adrenoceptor agonists were mediated predominantly by α1-adrenoceptors5,9 The present experiments were performed to assess the nature of α-adrenoceptor subtypes within these blood vessels in vivo. Dose/response relationships for adrenaline and noradrenaline pr...
