Abstract:
Tethered spinal cord is associated with closed and open neural tube defects. With prenatal screening, spinal defects are consistently diagnosed during fetal life. We show that the conus medullaris can be seen well with prenatal ultrasound, and the diagnosis of tethered spinal cord can be made during fetal life. In this pictorial essay, we show examples of tethered cord in a variety of fetuses with spine anomalies.

01:54The Spinal Cord
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.
01:16Spinal Cord: Cross-sectional Anatomy
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
