GENERAL HISTOLOGY

Detailed explanation-1: -The spinal cord is anchored distally by the filum terminale, a fibrous extension of the pia mater anchoring the spinal cord to the coccyx.

Detailed explanation-2: -[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.

Detailed explanation-3: -Cauda equina – The collection of nerves at the end of the spinal cord that resembles a horse’s tail.

Detailed explanation-4: -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.

Detailed explanation-5: -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.
