Dog 6, however, did not show any sign of disc protrusion, and the SAC was localised between the 7th and 8th thoracic vertebrae, a region not predisposed to herniated discs.
The numbers of vertebrae in each region and in total vary with the species.
A group of subvertebral muscles forms ventral to the vertebrae, in the region of their joints with the ribs at the transverse processes.
For all vertebrae, a cylinder region of interest (ROI, diameter 3 mm × height 4 mm) was chosen and reconstructed three-dimensionally using Micview software.
BMD was determined at various body regions (e.g., total body, arms, legs, trunk), the lumbar vertebrae, and hip regions (total hip, femoral neck, trochanter, femoral shaft).
The most prevalent findings were those located in the airway (42.3%), followed by the paranasal sinuses (30.9%), dentoalveolar (14.7%), surrounding hard/soft tissues (4.0%), temporomandibular joint (TMJ) (6.4%), and cervical vertebrae (1.3%) regions.
Presented case is unique in terms of extent of the affection (index finger, metacarp shaft, carpal bones, forearm, humerus and whole scapula) in combination with osteopoikilotic islands in other 3 regions (vertebrae, manubrium sterni and left collar bone).
Rodhocetus had well-developed hind limbs (although only the thighbone, or femur, has been preserved), but unlike land mammals, Rodhocetus did not have its vertebrae in the pelvic region fused together into a sacrum.
Some basic dinosaurian modifications to the ancestral archosaurian skeleton: Reduced fourth and fifth digits on the manus (hand); pes (foot) reduced to three main toes; three or more vertebrae composing the sacrum (region of the vertebral column which attaches to the pelvis); and an open acetabulum (hip socket; see below).
However, team doctors say that because of damage to two vertebrae in the neck region and because Cannon also suffers from a narrowing at the top of his spinal column, a congenital defect, he might risk a more severe injury, such as paralysis, if he plays again.
