During relaxation of a skeletal muscle:

1.	Calcium ions that are bound to troponin C now bind to troponin A
2.	Cross bridge formation between myosin head and actin takes place
3.	The A band of the sarcomere lengthens
4.	Calcium ions are pumped back to the sarcoplasmic cisternae

Abnormal curvature of the vertebral column where the alignment shows a lateral deviation is called as:

The superior and inferior radioulnar joints are examples of

What type of muscles do you expect to find in the inner walls of hollow visceral organs?

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
