Figure 5From: Ultrastructural analysis of development of myocardium in calreticulin-deficient miceMeasurement of the sarcomeric angle. An individual internal sarcomeric angle (α) was defined as an angle between a straight line connecting centres of adjacent Z-lines and a straight line connecting the centres of the initial and final Z-line of a given myofibril. To obtain average sarcomeric angle, all individual sarcomeric angles of a myofibril were averaged.Back to article page
