What is the D spine?

All five parts consist of individual bones called vertebrae. These are separated by interverbal discs, which cushion each vertebra between the bones. When combined, the spine is comprised of a total of 33 interlocking vertebrae. Cervical spine: 7 vertebrae (C1 – C7) Thoracic spine: 12 vertebrae (D1 – D12)

What does it mean to have a 6th vertebrae?

The C6 vertebra is the sixth cervical vertebra of the spine. It is found in the base of the neck between the C5 and the last cervical vertebra, C7. The C6 vertebra plays an important role in supporting and protecting the structures of the head and neck as well as anchoring the muscles that move and support the neck.

What does C6 vertebrae control?

C6 helps control the wrist extensors (muscles that control wrist extension) and also provides some innervation to the biceps. 1,3. The C6 dermatome covers the thumb side of the hand and forearm.

What is D12 fracture?

Vertebral compression fractures (VCFs) occur when the bony block or vertebral body in the spine collapses, which can lead to severe pain, deformity and loss of height. These fractures more commonly occur in the thoracic spine (the middle portion of the spine), especially in the lower part.

What causes an extra vertebrae?

The extra bone is essentially just a harmless anomaly; sometimes it’s because one vertebra failed to fuse with another, but in other cases it’s unclear why the bone appeared. L6 vertebrae don’t grow overnight. If you have the condition, you’ve always had it.

Where are the 6th dorsal and 7th dorsal vertebrae located?

6th Dorsal: A, Lower border of spine of D2; B, just below upper border of spine of D5. 7th Dorsal: A, Junction of upper 1/3 and lower 2/3 of spine of D4; B just above lower border of spine of D5.

What is the function of the T6 thoracic vertebrae?

The sixth thoracic vertebrae (T6), located just below the level of the shoulder blades, works in conjunction with the remaining 11 segments to protect the nerves of the spine. Each vertebra is larger than the one above it, increasing in diameter as they run the length of the spine. The larger the segment, the more weight it is able to support.

Where are the 5th and 5th lumbar vertebrae located?

3rd Lumbar: A, Middle of spine of D10; B, just below spine of D11. 4th Lumbar: A, Just below spine of D10; B, junction of upper 1/4 and lower 3/4 of spine of D12. 5th Lumbar: A, Junction of upper 1/3 and lower 2/3 of spine of D11; B, middle of spine of D12 1st Sacral: A, Just above lower border of spine of D11.

Where is the C6 spinal cord injury located?

These two muscles are located in the forearm and allow for wrist extension. Similarly, C6 spinal cord injury will affect sensation at the thumbs, index fingers, and part of the forearms. These are the sites that doctors will test to determine the level of spinal cord injury.
