The Widest Intervertebral Discs are Found in the ________ Region

Question

The widest intervertebral discs are found in the ________ region.
A) cervical
B) thoracic
C) lumbar
D) sacral
E) coccygeal

Accepted Answer

The lumbar region of the spine is known for having the largest and thickest intervertebral discs. This is due to the fact that the lumbar region supports a significant amount of body weight and experiences a lot of forces during movement. The cervical region has smaller intervertebral discs to allow for greater mobility, while the thoracic and sacral regions have less variability in disc size. The coccygeal region typically has no intervertebral discs.
