Question

BlackTom AI · Accepted Answer

The question asks which structure attaches the conus medullaris to the coccyx to stabilize the spinal cord.
Option 1: Filum terminale. This is the correct structure; the filum terminale (including its dural-anchored portion, the filum terminale externum) extends from the conus medullaris down to the coccyx and serves to anchor and stabilize the spinal cord within the vertebral column.
Option 2: Denticulate ligament. These lateral extensions of the pia mater suspend the spinal cord within the subarachnoid space and anchor it laterally to the arachnoid and dura, but they do not connect to the coccyx.
Option 3: Gray commissure. This is a band of gray matter that runs across the midline of the spinal cord, connecting the left and right sides of the anterior and posterior horns; it has no role in attaching the spinal cord to the coccyx.
Option 4: Ventral root. The ventral (anterior) root carries motor efferent fibers from the spinal cord to the body, not an anchor to the coccyx.
Option 5: Cauda equina. This term refers to the bundle of nerve roots below the conus medullaris that descend within the lumbar cistern; it does not function as an anchor to the coccyx.
