LIGAMENTUM DENTICULATUM Meaning and
Definition
-
The ligamentum denticulatum is a term used in anatomy to refer to a structure found within the spinal cord. It is a thin, delicate band of connective tissue that runs alongside the entire length of the spinal cord, attaching it to the dura mater, which is the tough, fibrous outer covering of the spinal cord.
The ligamentum denticulatum is composed of triangular-shaped bands that resemble teeth, hence its name, which translates to "toothed ligament." These tooth-like projections are also called denticulations. The ligamentum denticulatum is bilateral, meaning that there is a corresponding structure on each side of the spinal cord.
This structure serves several important functions. Firstly, it provides stability to the spinal cord, securing it within the spinal canal and preventing excessive movement. It acts as a suspensory ligament that keeps the spinal cord in position. Additionally, the ligamentum denticulatum forms a barrier between the various spinal nerve roots, keeping them organized and preventing them from tangling or rubbing against each other.
The ligamentum denticulatum also contributes to the protection of the spinal cord by reducing excessive movement that could potentially cause damage to this vital neural tissue. It acts as a shock absorber, cushioning the spinal cord against external forces and minimizing the risk of trauma.
In summary, the ligamentum denticulatum is a tooth-like band of connective tissue that anchors the spinal cord, provides stability, organizes nerve roots, and protects the spinal cord from trauma.

Denticulate ligament, the suspensory ligament of the spinal cord in its dura mater sheath; a fibrous band, extending from the spinal pia mater on either side, which presents on its outer or free edge from twenty to twenty-three or more triangular projections, the tips of which, together with the arachnoid covering them, are attached to the inner surface of the dura mater in the intervals between the nerve-roots.

Etymology of LIGAMENTUM DENTICULATUM
The term "ligamentum denticulatum" originates from Latin, where "ligamentum" means "ligament" and "denticulatum" means "small tooth" or "tooth-like". The word is derived from the Latin words "ligamentum", which can be traced back to the verb "ligare" meaning "to bind" or "to tie", and "denticulatum", a diminutive form of "dens" meaning "tooth". The name "ligamentum denticulatum" was given to a specific ligament in the brain and spinal cord due to its tooth-like appearance when seen under a microscope.
