Conus medullaris - Wikipedia
The conus medullaris (Latin for "medullary cone") or conus terminalis is the tapered, lower end of the spinal cord. It occurs near lumbar vertebral levels 1 (L1) and 2 (L2), occasionally lower. [1] [2] The upper end of the conus medullaris is usually not well defined, however, its corresponding spinal cord segments are usually S1–S5.

2023年8月7日 · The lowermost tapering extremity of the spinal cord is called the conus medullaris, which is around the first or second lumbar vertebra and can sometimes be lower. The upper border of the conus medullaris is usually poorly defined.

2024年12月9日 · The Adamkiewicz artery is one of the thoracolumbar radicular arteries, a primary supplier of the lower thoracic and lumbar spinal cord, including the conus medullaris. The initial presentation of spinal cord infarction includes acute or sudden onset of back pain with bilateral sensory impairment.
Conus Medullaris Syndrome | SpinalCord.com
Conus medullaris syndrome is a secondary form of spinal cord damage resulting from injuries to the lumber vertebrae. The conus medullaris is the bundled, tapered end of the spinal cord nerves. Situated near the first two lumbar vertebrae, the conus medullaris ends at the cauda equina, a bundle of spinal nerves and nerve roots.
The Filum Terminale: A Cadaver Study of Anatomy
2016年6月1日 · The most distal segment of the spinal cord, the conus medullaris (CM), terminates in the filum terminale internum (FTI), which reaches the distal termination of the dural sac (DS). Caudally, the filum terminale externum (FTE) spans from the DS to the periosteum of the coccyx (CX).

2016年6月1日 · That mechanism exposes the conus medullaris to unphysiologic stretch forces, causing TCS, especially when considering the hypermobile spine in hEDS. This notion is supported by the observed clinical improvement following FT resection in hEDS-TCS cases without a low-lying conus.
Cauda Equina and Conus Medullaris Syndromes
2023年8月7日 · Conus medullaris syndrome (CMS) results when there is compressive damage to the spinal cord from T12-L2. The cauda equina is a group of nerves and nerve roots stemming from the distal end of the spinal cord, typically levels L1-L5 and contains axons of nerves that give both motor and sensory innervation to the legs, bladder, anus, and perineum.

Conus medullaris | Radiology Reference Article - Radiopaedia.org
2024年4月23日 · The conus medullaris is conical in shape, tapering from the distal spinal cord to a narrow point from which a delicate strand of fibrous tissue called the filum terminale extends down to the sacrum and acts to give longitudinal support to the cord.

The spinal cord highlighted in slice 1651 may be the filum terminale. It will continue down to the sacrum. Observe the cross sections both superiorly into the conus medularis and inferiorly from slice 1651 to follow the non-labeled filum terminale to the sacrum.) (G 1.38;N 165;Gl 4.9)
