Human axial skeleton
-
Which of the following statements are correct with reference to human endoskeleton? I. Human skull is monocondylic. II. The joint between any two adjoining vertebrae is a cartilaginous joint. III. In human beings, the number of cervical vertebrae is seven. IV. All ribs except the last 2 pairs are bicephalic. V. The occipital bone of skull is articulated with atlas vertebra.

Sliding filament theory of muscle contraction
-
Choose the correct statements regarding muscle contraction. I. A motor neuron carries a signal sent by the Central Nervous System (CNS) to the sarcolemma of the muscle fibre. II. The neural signal generates an action potential which causes the release of $Ca^{++}$ into sarcoplasm. III. Increase in $Ca^{++}$ inactivates the actin for breaking cross bridges. IV. Actin binds to the myosin head to form a cross bridge. V. Shortening of sarcomere takes place by pulling actin filaments towards the centre of 'A' band. Choose the CORRECT answer from the options given below:
