Go through the following statements During muscle contraction, the width of A-band remains constant while I-band shortens. During muscle contraction, the Ca^(2+) released from the SR bind to the troponin component of thin filament The process of muscle contraction is faster in smooth muscle as they have a well developed sarcoplasmic reticulum. The red muscle fibres have abundant mitochondria, low glycogen and poorly formed sarcoplasmic reticulum.

Go through the following statements (i) Vagus nerve decreases the rate of impulse formation from the SA node and its conduction (ii) As the human heart is myogenic in nature, the rate of formation and conduction of cariac impulse cannot be changed by the action of nerves (iii) The end of T-wave in ECG marks the end of systole. (iv) If the P-wave in ECG is inverted , it indicates that SA node fails to initiate impulse and the atrial muscle depolarises by the impulse originating in A.V. node. Which of these are correct ?
