Which of the following statements about the mechanism of muscle contraction are correct ? (i) Acetylcholine is released when the neural signal reaches the motor end plate. (ii) Muscle contraction is initiated by a signal sent by CNS via sensory neuron. (iii) During muscle contraction, isotropic band gets elongated (iv) Repeated activation of the muscles can lead to lactic acid accumulation.

Read the following statements regarding muscle contraction (i) One ATP utillised for making and breaking of the cross bridge. (ii) The sarcomere lies between 2 Z-lines (iii) Troponin blocks the active sites in resting stage (iv) Ca^(++) ions help in unmasking active sites on HMM Choose the correct option

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. Whic of these are correct ?

Go through the following statements (i) The inner surface of atria have got transverse muscular ridges called papillary muscles. (ii) Chordae tendinae are special fibrous cords attached to the AV valves and prevent them from collapsing back into the atria during powerful vantricular contraction (iii) The neurogenic heart stops functioning immidiately after removal from the body. (iv) The conduction of cardiac impulse is slowest in the A.V. node. Which of these are correct ?
