What is the lateral projection of a vertebra?
Two projections, extending laterally from the junction of the pedicles and lamina, are called the transverse processes. The spinous process projects posteriorly and inferiorly from the junction of the lamina. Four articular processes extend superiorly and inferiorly from the junction of the pedicles and lamina.
What is the lateral part of sacrum?
The two projections at the sides of the sacrum are called the alae (wings), and articulate with the ilium at the L-shaped sacroiliac joints. The upper part of the sacrum connects with the last lumbar vertebra (L5), and its lower part with the coccyx (tailbone) via the sacral and coccygeal cornua.
Where is the sacral vertebrae located?
The sacrum is a shield-shaped bony structure that is located at the base of the lumbar vertebrae and that is connected to the pelvis. The sacrum forms the posterior pelvic wall and strengthens and stabilizes the pelvis.
Where is the center of the lateral sacrum and coccyx?
Technical factors
- lateral view.
- centering point. 8-10 cm posterior to the ASIS 1
- central ray. angled perpendicular to the IR (90°)
- collimation. superior to include the L5/S1 articulation. inferior to include the distal coccyx.
- orientation. portrait.
- detector size. 24 x 30 cm.
- exposure. 80 kVp. 30-40 mAs.
- SID. 110 cm.
What is demonstrated on lateral C spine?
Lateral projection of the cervical spine This projection suffices to demonstrate most traumatic conditions of the cervical spine, including injuries involving the anterior and posterior arches of C-l; the odontoid process, which is seen in profile; and the anterior atlantal-dens interval.
What are the lateral projections on both sides of the vertebral arch?
Most thoracic vertebrae have two facets located on the lateral sides of the body, each of which is called a costal facet (costal = “rib”). These are for articulation with the head (end) of a rib. An additional facet is located on the transverse process for articulation with the tubercle of a rib.
How are sacral vertebrae different?
The sacrum and coccyx are unlike other bones in your spinal column. The sacrum, sometimes called the sacral vertebra or sacral spine (S1), is a large, flat triangular shaped bone nested between the hip bones and positioned below the last lumbar vertebra (L5).
What are sacral vertebrae?
The sacrum, sometimes called the sacral vertebra or sacral spine (S1), is a large, flat triangular shaped bone nested between the hip bones and positioned below the last lumbar vertebra (L5). The coccyx, commonly known as the tailbone, is below the sacrum.
What is sacral vertebra?
What is cervical spine AP and lateral?
An X-ray technician takes the X-rays. Usually, three different pictures usually are taken of the cervical spine: one from the front (AP or anterior-posterior view), one from the side (lateral view), and another from the front through an open mouth (odontoid view).
What anatomical structures are best demonstrated on a lateral cervical spine?
XR 105 Midterm

When to use the sacrum and coccyx lateral view?
The sacrum and coccyx lateral view is utilized to demonstrate the most distal region of the spine in a lateral position. It is commonly used in conjunction with the AP projection or can be used as a sole projection, depending on department protocols.
Where are the sacral vertebrae located in the body?
The sacral vertebrae —also called the sacral spine—consists of five sacral vertebrae bones. These bones fuse together to form the sacrum, the shield-shaped bony structure located at the base of the lumbar vertebrae (the five cylindrical bones forming the spine of the lower bank) and connected to the pelvis.
What are the four regions of the vertebral column?
Left lateral view. The vertebral column (spine) is divided into four regions: the cervical, thoracic, lumbar, and sacral spines. Both the cervical and lumbar spines demonstrate lordosis (inward curvature); the thoracic and sacral spines demonstrate kyphosis (outward curvature). A Regions of the spine.
What are transverse lines on the sacral vertebra?
The transverse lines are horizontal ridges on the concave anterior sacral surface that mark the edges of the fused sacral vertebrae. The superior articular facets of the sacrum articulate with facets on the inferior articular processes of the most inferior lumbar vertebra.
