What forms the cauda equina and filum terminale?
The space inside the arachnoid mater is filled with cerebrospinal fluid (CSF). Below the conus medullaris, this space is enlarged. This enlargement is called the lumbar cistern and contains CSF, the filum terminale, and the cauda equina.
Is the filum terminale part of the spinal cord?
Disorders of Neural Tube Development The filum terminale is the nonfunctional continuation of the end of the spinal cord. It usually consists of fibrous tissue without functional nervous tissue.
Does the filum terminale stabilize the spinal cord?
The filum terminale (FT) is a fibrous band that extends from the conus medullaris to the periosteum of the coccyx, and its functions are to fixate, stabilize, and buffer the distal spinal cord from normal and abnormal cephalic and caudal traction.
What does the filum terminale attach to?
The lower part, or filum terminale externum, closely adheres to the dura mater. It extends downward from the apex of the tubular sheath and is attached to the back of the first segment of the coccyx in a structure sometimes referred to as the coccygeal ligament.
What is the difference between cauda equina and filum terminale?
The fibrous extension of the cord, the filum terminale, is a nonneural element that extends down to the coccyx. The cauda equina (CE) is a bundle of intradural nerve roots at the end of the spinal cord, in the subarachnoid space distal to the conus medullaris.
Is the filum terminale part of the cauda equina?
Is cauda equina part of spinal cord?
The spinal cord ends in the lumbar area and continues through the vertebral canal as spinal nerves. Because of its resemblance to a horse’s tail, the collection of these nerves at the end of the spinal cord is called the cauda equina.
Does the cauda equina include the filum terminale?
Caudal Anesthesia The sacral canal contains the cauda equina (including the filum terminale), the spinal meninges, adipose tissue, and the sacral venous plexus.
Is filum terminale the same as cauda equina?
