Answer 21

the costal element

Question 22

What will cause the transverse process / transverse apophysis to alter its intial direction in the cervical region?

Answer 22

cervical spinal nerves are pulleed forward and downward to form the cervical and brachial plexuses thus remodeling the transverse process to accommodate their new position

Question 23

What will cause the transverse process / transverse apophysis to alter its intial direction in the thoracic region?
