When the calcium concentration in the medium is reduced to, say, one-eighth of the normal, a similar stimulus produces no mechanical response. If the effect of partial or total calcium dep

However, three major questions concerning the calcium-dependent secretion of catecholamines remain unanswered. These are, first, how is calcium entry into chromaffin cells regulated; second, what is the nature of the process activated by calcium;

Thus the synaptic release of acetylcholine and noradrenaline is calcium dependent (Harvey & MacIntosh, 1940; del Castillo & Stark, 1952; Hukovi? & Muscholl, 1962; Kirpekar & Misu, 1967); but so, too, is the release of many hormones (Table 1).

This was known to be true in a descriptive sense several years ago (Woodin & Wieneke, 1966a), and recent work suggests that it is also true of the mechanisms.

Evidence touching upon these three questions is discussed here.
