Lumbarization of S1 or lumbarization of first sacral vertebra is a condition in which the first sacral vertebra is not completely attached to its fused sacral components but instead this first sacral vertebra appears like the other lumbar vertebrae. lateral pterygoid. Macrophages are found in areolar and lymphatic tissues. The sacral region (sacrum) is at the bottom of the spine and lies between the fifth segment of the lumbar spine (L5) and the coccyx (tailbone). It looks like a single bony component composed of 5 fused vertebrae (S1-S5). vertebrae [L. The vertebra prominens, or C7, has a distinctive long and prominent spinous process, which is palpable from the skin surface. This type of fracture can occur in a head-on car collision when the upper body is thrown forward while the pelvis is stabilized by a lap seat belt. Anatomy and Function of the Spine. The spinal cord runs through its center. Our vertebral column is composed of 33 irregular sized bones that are connected to each other by intervertebral discs. Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull. The atlas articulates superiorly with the occipital condyles found on each side of the foramen magnum of the skull. Underneath the atlas lies the C2 vertebra (also known as the axis). This occurs most often in the lower vertebrae in the thoracic spine. Your thoracic spine is the middle section of your spine.
