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. 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.

Which of the following statements are true ? (i) Sudden action in response to something in the environment is called reflex action (ii) Sensory neurons carry signals from spinal cord to muscles (iii) Motor neurons carry signals from receptors to spinal cord (iv) The path through which signals are transmitted from a receptor to a muscle or a gland is called reflex arc

    Which of the following statements given below are true with reference to muscle contraction. I. Neurotransmitter acetycholine is released as nerve impulse reaches the end of axon and binds to receptor sites of motor end plate. II. Action potential passes from motor end plate over sarcoplasmic and then into the T-tubules and sarcoplasmic reticulum. III. Calcium ion are released into the sarcoplasm bind to troponin, causing a change in its shape and position. IV. Myosin cross bridges are able to bind to exposed active sites of actin. Choose the correct option.
