What is the extension of the pia mater that extends inferiorly and fuses with the arachnoid mater and dura mater to anchor the spinal cord to the coccyx?
filum terminale
The filum terminale is an extension of the pia mater that is attached to the coccygeal segments, whose function is to suspend the cord in the CSF (like the denticulate ligaments). The arachnoid and dura mater extend beyond the L2 level to the level of the S2 vertebra.
Which PIAL extension anchors the spinal cord to the posterior coccyx?
Structure and Function [4] The pia mater of the tapering end of the conus continues downward as the filum terminale, which is a delicate strand of fibrous tissue about 20 cm in length. This structure serves to stabilize the spinal cord by connecting the conus to the coccyx via the coccygeal ligament.
Does the spinal cord extend to the coccyx?
The spinal cord lies inside the spinal column, which is made up of 33 bones called vertebrae. Five vertebrae are fused together to form the sacrum (part of the pelvis), and four small vertebrae are fused together to form the coccyx (tailbone).
What attaches the conus medullaris to the coccyx?
Filum terminale This strand stabilizes the spinal cord by connecting the conus medullaris to the coccyx (end of the spine).
What is an extension of pia mater?
The spinal cord is anchored distally by the filum terminale, a fibrous extension of the pia mater anchoring the spinal cord to the coccyx. [1] Protecting the spinal cord is the surrounding cerebrospinal fluid (CSF), supportive soft tissue membranes and meninges, and the osseous vertebral column.
What happens to the pia mater inferior to the spinal cord?
Inferiorly, the spinal pia mater fuses with the filum terminale. Between the nerve roots, the pia mater thickens to form the denticulate ligaments. These ligaments attach to the dura mater – suspending the spinal cord in the vertebral canal.
Why is the pia mater important?
Together with the other meningeal layers, the function of the pia mater is to protect the central nervous system by containing the cerebrospinal fluid, which cushions the brain and spine. The cranial pia mater covers the surface of the brain.
Can cauda equina cause pelvic pain?
Chronic CES, defined as persistent damage of the cauda equina nerve roots within the spinal canal, can be a challenging diagnosis with varied presentations of lower spinal symptoms, pelvic pain, gastrointestinal symptoms, urologic issues, and other chronic neurologic problems.
What happens if the pia mater is damaged?
The perivascular space between blood vessels and pia mater is proposed to be part of a pseudolymphatic system for the brain (glymphatic system). When the pia mater becomes irritated and inflamed the result is meningitis.
Can the pia mater be removed?
Pia Mater. The surfaces of the brain and spinal cord are lined with a firmly attached layer of pia mater. Unlike the arachnoid, the pia follows all contours of the brain and spinal cord and can not be removed with out damaging the underlying neural tissue.
What are the symptoms of Myelomalacia?
The Causes and Symptoms of Myelomalacia
- Pain.
- Muscle weakness.
- Motor function impairment.
- Delayed or inhibited reflexes.
- Difficulty breathing.
How do you relieve spinal cord pain?
7 Ways to Relieve Back Pain Naturally

- Avoid prolonged static posture.
- Gently stretch your joints and soft tissues through yoga.
- Try mindful meditation.
- Support your body in a warm pool.
- Keep a self-activating heat patch handy.
What are red flags for cauda equina?
Red flag symptoms Bilateral sciatica (pain and altered sensation in the legs) Bladder dysfunction such as having to strain or an altered flow or altered awareness of the need to urinate. Tingling or numbness in the saddle area between the legs and around the anus. Alteration of sexual sensation.
What is the treatment for conus medullaris?
Treatment for Conus Medullaris Syndrome Spinal decompression surgery often helps, and if a physical impediment to function remains—such as a tumor or the remnants of a bullet—your doctor may remove these to restore spinal function. Radiation may help if your symptoms are due to cancer.
What is cauda equina vs conus medullaris?
The most distal bulbous part of the spinal cord is called the conus medullaris, and its tapering end continues as the filum terminale. Distal to this end of the spinal cord is a collection of nerve roots, which are horsetail-like in appearance and hence called the cauda equina (Latin for horse’s tail).
