Now, on the posterior side, you find, as well, another line, letâs say, but this time called the intertrochanteric crest that is also between the neck of the femur and the shaft and runs, as well, from the greater trochanter all the way down to the lesser trochanter.
The upper back has the most structural support, with the ribs attached firmly to each level of the thoracic spine and very limited movement. The lower back (lumbar vertebrae) allows for flexibility and movement in back bending (extension) and forward bending (flexion).
Please try again later. The thoracic spinal vertebrae consist of 12 total vertebrae and are located between the cervical vertebrae (which begin at the base of the skull) and the lumbar spinal vertebrae. The second thoracic vertebra, or T2, is located directly below the first thoracic vertebra (T1).
