Final answer:
The normal range of cervical rotation is between 60 and 75 degrees, which is option B. The cervical region has the greatest range of motion for rotation in the vertebral column.
Step-by-step explanation:
The normal range of cervical rotation to each side is generally considered to be between 60 and 80 degrees. So, among the options provided:
- A) 45-60 degrees
- B) 60-75 degrees
- C) 75-90 degrees
- D) 90-110 degrees
the most accurate answer would be B) 60-75 degrees. This range allows for functional movement of the head in relation to the body without exceeding the anatomical limitations of the cervical spine. To clarify, the cervical region of the vertebral column does have the greatest range of motion for rotation compared to the thoracic, lumbar, and sacral regions.
