Fig. 4From: Thyroxin and calcitonin secretion into thyroid venous blood is regulated by pharyngeal mechanical stimulation in anesthetized ratsSummary of changes in the secretion rates of iT4 (a), iCT (b), and iPTH (c) in thyroid venous blood plasma in response to pharyngeal stimulation. Each column and vertical bar indicates mean ± SE (n = 6 in four rats). **p < 0.01; significantly different from prestimulus control values, using a paired t testBack to article page
