During muscle contraction, when the myosin head releases ADP and iP it:
1. forms cross bridge with actin
2. pulls actin towards M-line
3. goes back to its relaxed state
4. gets detached from the cross bridge

Which of the following masks the active sites on actin when a skeletal muscle is relaxed?

All the following are cranial bones except:

During muscle contraction, the event shown in the following diagram describes:

1. cross bridge detachment
2. the power stroke or working stroke
3. cross bridge formation
4. cocking of myosin head

The pubic bones, constituent of the coxal bone, are held together ventrally by a:
1. syndesmosis
2. diarthrotic
3. symphysis
4. synchondrosis

The total number of vertebrosternal and vertebrochondral ribs in human body respectively are:

The total number of phalanges in the human body are:

Progressive degeneration of skeletal muscle mostly due to genetic disorder is called:

An example of a fibrous joint ‘gomphosis’ in the human body is:
