What the sources say

“Intervertebral Disc An intervertebral disc is a fibrocartilaginous pad that fills the gap between adjacent vertebral bodies (see Figure 7.24 ).” Betts et al. 2022, §7.3
“The disc consists of a fibrous outer layer called the anulus fibrosus and a gel-like center called the nucleus pulposus.” Betts et al. 2022, §7.3
“Because of this, intervertebral discs are thin in the cervical region and thickest in the lumbar region, which carries the most body weight.” Betts et al. 2022, §7.3
