Yes, an intervertebral disc functions as a ligament.
While an intervertebral disc's primary roles are shock absorption and enabling slight movement between vertebrae, it also serves to hold adjacent vertebrae together. This holding function aligns with the definition of a ligament.
Here's a breakdown:
-
Intervertebral Discs: These are fibrocartilaginous structures located between vertebrae in the spine.
-
Functions of Intervertebral Discs:
- Shock Absorption: Discs cushion the vertebrae during movement and impact.
- Movement: They allow for a small range of motion between vertebrae.
- Ligamentous Role: They connect vertebrae, preventing excessive movement and maintaining spinal stability.
-
Ligaments: By definition, ligaments are fibrous connective tissues that connect bones to other bones. Intervertebral discs perform this function, contributing to the stability of the spine.
Therefore, while not solely a ligament, an intervertebral disc does act as a ligament due to its role in connecting adjacent vertebrae.
