cauda equina
The band that attaches the dura mater to the spinal cord is called the dentate ligaments. These ligaments provide stability and support to the spinal cord within the spinal column.
The inferior continuation of the pia mater to the coccyx is the filum terminale, a slender filament of connective tissue. It helps to anchor the spinal cord within the spinal canal and provides longitudinal support to the spinal cord.
The outside of the Dura Mater (a protective layer of the spinal cord and brain) of the spinal cord.
The dura mater is the outermost membrane of the brain and spinal cord. The dura mater is is responsible for keeping in the cerebrospinal fluid.
The brain and spinal cord. The cephalic portion of the nueral tube becomes the brain, the caudal portion becomes the spinal cord.
Spinal cord, spinal nerve roots, and Dura mater
The lateral extensions of the pia mater into the vertebrae are called denticulate ligaments. They anchor the spinal cord to the dura mater within the vertebral canal and help stabilize the spinal cord within the spinal column.
If you are referring to the spinal cord then the vertebrae, dura mater, arachnoid mater and pia mater. If referring to the actual bones then supportive muscles, intervertebral discs, connective tissue including adipose (fat).
Pia Mater
To cushion your brain and spinal cord and provide nutrients for the brain. It is found in the ventricular system, in the brain and spinal cord and the subarachnoid space between the pia mater and the arachnoid mater of the meninges.
The meninges, i.e. the membranes that surround the brain and spinal cord.
An arachnoid mater is a membrane which protects the brain and spinal cord below the dura mater and above the subarachnoid space and the pia mater.
