Spinal Cord Levels
The corresponding spinal cord levels for C1-C6 and T1-T12 are not directly stated in the provided studies. However, the studies provide information on the anatomy and measurements of the spinal cord.
Cervical Spinal Cord Levels
- The study 1 measured the normal measurements of the C1-T3 spinal cord on MR imaging and found that the cord varies in average anteroposterior and transverse diameters from 8.8 mm x 12.4 mm at C2 to 8.7 mm x 14 mm at C4 to 7.4 mm x 11.4 mm at C7.
- The study 2 measured the space available for the cervical spinal cord of asymptomatic adult Nigerians and found that the average SAC values were 4.9±1.4 mm (C3/4), 4.5±1.2 mm (C4/5), 4.6±1.4 mm (C5/6), and 4.9±1.2 mm (C6/7).
Thoracic Spinal Cord Levels
- The study 3 investigated the variations and levels of lumbar and sacral spinal cord segments with reference to the axilla of the T11, T12, and L1 spinal nerve roots and adjacent vertebrae, but did not provide direct information on the corresponding spinal cord levels for T1-T12.
- The study 4 evaluated the intra-rater agreement of repeated motor and sensory scores at individual spinal levels, including T1-T6 and T7-T12, but did not provide direct information on the corresponding spinal cord levels.
Limitations
There are no direct research papers to assist in answering the question of corresponding spinal cord levels for C1-C6 and T1-T12. The provided studies focus on the anatomy, measurements, and variations of the spinal cord, but do not provide a clear mapping of spinal cord levels to vertebral levels.
