It plays an essential structural role in anchoring the spinal cord in place.<\/p>\n\n\n\n<p>The spinal cord ends at a point called the <strong>conus medullaris<\/strong>, usually around the <strong>L1 or L2 vertebra<\/strong> in adults. From this point downward, the terminal filum continues as a fibrous strand. It passes through the <strong>lumbar cistern<\/strong>, a space filled with cerebrospinal fluid (CSF) and nerve roots called the <strong>cauda equina<\/strong>.<\/p>\n\n\n\n<p>The terminal filum has two parts:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Filum terminale internum<\/strong> \u2013 the upper portion (about 15 cm long), located <strong>within the dural sac<\/strong>, surrounded by nerve roots of the cauda equina.<\/li>\n\n\n\n<li><strong>Filum terminale externum<\/strong> \u2013 the lower portion (about 5 cm), outside the dural sac. This part attaches to the <strong>coccyx<\/strong>, anchoring the spinal cord and meninges to the vertebral column.<\/li>\n<\/ol>\n\n\n\n<p>Functionally, the terminal filum prevents <strong>upward movement<\/strong> of the spinal cord and <strong>helps stabilize<\/strong> it within the vertebral canal. It does <strong>not contain nerve tissue<\/strong>, although it is surrounded by spinal nerves in the cauda equina.<\/p>\n\n\n\n<p>Clinically, abnormalities in the terminal filum (like a <strong>thickened filum<\/strong>) can lead to conditions such as <strong>tethered cord syndrome<\/strong>, where the spinal cord is abnormally attached, causing stretching and neurological problems.<\/p>\n\n\n\n<p>In summary, the terminal filum is a key structural feature of the spinal cord anatomy, extending from the conus medullaris to the coccyx, ensuring stability and proper placement of the spinal cord within the vertebral column.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Where is the terminal filum found?
