The twelfth thoracic vertebra has the same general characteristics as the eleventh, but may be distinguished from it by its inferior articular surfaces being convex and directed lateralward, like those of the lumbar vertebrae; by the general form of the body, laminae, and spinous process, in which it resembles the lumbar vertebrae; and by each ...
The rib cage or thoracic cage is an endoskeletal enclosure in the thorax of most vertebrates that comprises the ribs, vertebral column and sternum, which protect the vital organs of the thoracic cavity, such as the heart, lungs and great vessels and support the shoulder girdle to form the core part of the axial skeleton.
The lower half of one sclerotome fuses with the upper half of the adjacent one to form each vertebral body. [20] From this vertebral body, sclerotome cells move dorsally and surround the developing spinal cord, forming the vertebral arch. Other cells move distally to the costal processes of thoracic vertebrae to form the ribs. [20]
In the thoracic region, the sides of the bodies of the vertebrae are marked in the back by the facets for articulation with the heads of the ribs. More posteriorly are the intervertebral foramina, formed by the juxtaposition of the vertebral notches, oval in shape, smallest in the cervical and upper part of the thoracic regions and gradually ...
The picture displays the mediastinum on sagittal plane, thoracic diaphragm at the bottom, the heart (cor), behind sternum and ribs (to the left on the picture (this is the anterior/front) and to the right (posterior/back)), you have the thoracic vertebrae. The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is ...
Adopting a forward head and rounded shoulders posture places increased stress on the neck (cervical spine), mid-back (thoracic spine) and low back (lumbar spine), Dr. Halfman explains.
Vertebral hemangiomas are observed throughout any age, although most are diagnosed in people within their 50s alongside a higher presence in females with a 1:1.5 male-to-female ratio. They often present in the vertebral body of the thoracic and lumbar spine with potential to extend into the posterior arch. They can involve a single or multiple ...
They also detected a hemangioma, which is a benign growth filled with blood and blood vessels, in the T10 vertebrae of my thoracic spine. These typically won’t cause pain or grow, so because I ...
