Functions of intervertebral discs
- Shock absorption
- Flexibility
- Creates lordotic curve in cervical
and lumbar spine - Height
Structure of intervertbral discs
- Annulus Fibrosis
* Outer layer
* Fibrocartilaginous - Nucleus pulposus
* Inner layer
* Gel-like matrix
Intervertebral discs
Take on the shape/size of its
vertebral bodies
In lumbar and cervical spine: is
thicker anteriorly and thinner
posteriorly
Creates lordotic curve
Suprahyoids - Origins are superior to hyoid
Insert onto hyoid
Digastric
Geniohyoid
Mylohyoid
Stylohyoid
