Which of the following statements about cross-bridges is false?
1. They are composed of myosin
2. They bind to ATP after they attach to actin
3. They contain an ATPase
4. They split ATP before they attach to actin

The role of calcium in muscle contraction is

1. to break the cross-bridges as a cofactor in the
hydrolysis of ATP

2. to bind with troponin, changing its shape so that
the actin filament is exposed

3. to transmit the action potential across the
neuromuscular junction

4. to spread the action potential through the T
tubules

Select the mismatch

Select the correct statement regarding the specific disorder of muscular or skeletal system

1. Myasthenia gravis- Autoimmune disorder which inhibits sliding of myosin filaments.

2. Gout-inflammation of joints due to extra deposition of calcium.

3. Muscular dystrophy-Age related shortening of muscles.

4. Osteoporosis-Decrease in bone mass and higher chances of fractures with advancing age.

2. The 9th and 10th pairs of ribs are called the floating ribs

3. Glenoid cavity is a depression to which the thigh bone articulates 

4. Parietal bone and the temporal bone of the skull are joined by fibrous joint
