  2. Lumbar vertebrae - Wikipedia

    en.wikipedia.org/wiki/Lumbar_vertebrae

    In human anatomy, the five vertebrae are between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region).

  3. Thecal sac - Wikipedia

    en.wikipedia.org/wiki/Thecal_sac

    The lumbar cistern is part of the subarachnoid space.It is the space within the thecal sac which extends from below the end of the spinal cord (the conus medularis), typically at the level of the first to second lumbar vertebrae down to tapering of the dura at the level of the second sacral vertebra.

  4. Spinal column - Wikipedia

    en.wikipedia.org/wiki/Spinal_column

    The spinal column, also known as the vertebral column, spine or backbone, is the core part of the axial skeleton in vertebrates. The vertebral column is the defining and eponymous characteristic of the vertebrate. The spinal column is a segmented column of vertebrae that surrounds and protects the spinal cord.

  5. Axial skeleton - Wikipedia

    en.wikipedia.org/wiki/Axial_skeleton

    The axial skeleton is the core part of the endoskeleton made of the bones of the head and trunk of vertebrates. In the human skeleton , it consists of 80 bones and is composed of the skull (28 bones, including the cranium , mandible and the middle ear ossicles ), the vertebral column (26 bones, including vertebrae , sacrum and coccyx ), the rib ...

  6. Spinal fMRI - Wikipedia

    en.wikipedia.org/wiki/Spinal_fMRI

    Functional magnetic resonance imaging (fMRI) of the spinal cord (spinal fMRI) is an adaptation of the fMRI method that has been developed for use in the brain. Although the basic principles underlying the methods are the same, spinal fMRI requires a number of specific adaptations to accommodate the periodic motion of the spinal cord, the small cross-sectional dimensions (roughly 8 mm × 15 mm ...

  7. Magnetic resonance myelography - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_myelography

    Magnetic resonance myelography (MR myelography or MRI myelography) is a noninvasive medical imaging technique that can provide anatomic information about the subarachnoid space. It is a type of MRI examination that uses a contrast medium and magnetic resonance imaging scanner to detect pathology of the spinal cord , including the location of a ...

  8. Pars interarticularis - Wikipedia

    en.wikipedia.org/wiki/Pars_interarticularis

    On an anterior oblique radiograph of the lumbar spine, the pars is the neck of the imaginary Scottie dog; the Scottie dog's eye is the pedicle, [3] its hindlegs the spinous process, its nose the transverse process, its ear the superior articular facet and its forelegs the inferior articular facet.

  9. Anatomical plane - Wikipedia

    en.wikipedia.org/wiki/Anatomical_plane

    A transverse plane (also known as axial or horizontal plane) is parallel to the ground; it separates the superior from the inferior, or the head from the feet. The transverse planes identified in Terminologia Anatomica are the transpyloric plane , the subcostal plane , the transumbilical (or umbilical) plane , the supracristal plane , the ...
