Problem to be solved: to provide a vertebral body spacer capable of improving the connectivity with the living bone and ensuring the insertion between the vertebrae. The spacer spacer 10 of the present invention is inserted between the first and second vertebral bodies in a predetermined insertion ...
• Describe the general structure of vertebrae and identify the structural components on a diagram. • State the characteristics that distinguish cervical vertebrae from other types. • Distinguish the first two cervical vertebrae from other cervical vertebrae and state their specific names. • Id...
levels of the spinal canal (Fig. 1.10). There are eight cervical nerve roots but only seven cervical vertebrae; each nerve root except the eighth emerges above the correspondingly numbered vertebra. In the remainder of the spine, the nerve roots emerge below the correspondingly numbered vertebrae....
The second study of low RoB30 compared SMT at the candidate site (upper cervical vertebrae) to multiple SMTs at non-candidate sites and reported no between-group difference in neck pain intensity. The final study, which was of moderate RoB29, chose C7 as the candidate site (the clinician ...
After complete perfusion, the spinal cord between vertebrae T8–T10 (inclusive thoracolumbar spinal cord levels T10–T12), T11–T13 (inclusive thoracolumbar spinal cord levels T13-L1) and vertebra L1-L5 (inclusive lumbosacral spinal cord levels L5-S1) was removed and post-fixed in 4% paraformal...
the spinal discs lose their elasticity. They can lose their gel-like fluid and become brittle and cracked. In adults, it is due to lifting a heavy object or accident. These discs, also known as the nucleus pulposus, are between 2 vertebrae. Once slipped, the disc impinges on the nearby ...

The vertebral column comprises seven cervical, twelve thoracic, and five lumbar segments. In adults, the cord terminates at the level of L1 to L2. Thus, the cord spans within 20 bony vertebrae. In a child, it terminates at the upper border of L3. Each of these segments innervates a de...
The procedure of T7 and T12 staggered double hemisection was similar to that described elsewhere15. Briefly, a midline incision was made over the thoracic vertebrae, followed by a T7–12 laminectomy. For the lateral hemisection, we inserted a custom-made half-open needle (32-gauge) from the...
25. By removing muscle and ligament tissues between adjacent vertebrae, the spinal cord was imaged with only dura left. Using this protocol, it is reported that microglia activation was not observed by 2-hour time-lapse imaging after surgery, though clear microglia imaging and quantitative analysis...
