hypermobility

Question 19

(true/false) When you see a segment that is hypermobile, there are typically hypomobile segments close by that are creating more stress on the hypermobile segment.

true

Question 21

With acute disc herniation, The nucleus pulposus of a cervical disc typically herniates________through the annulus fibrosis and often compresses on the nerve root located on the side of herniation.

Answer 21

posterolaterally

Question 22

(true/false) Irritation of the nerve root w/ an acute disc herniation can occur directly from the disc pressing on it. It can also occur from the release of chemicals and inflammatory mediates that come in contact with nerve root due to the herniation.

Answer 22

true

Question 23

Is it more common to get an acute disc herniation in a younger or older population? why?
