Strong but short; form deep vertebral notches in the lumbar region.
The pedicles are the thick bony structures that connect the vertebral body to the lamina in the vertebral column. They form the sides of the vertebral arch and help to protect the spinal cord. In the lumbar region, the pedicles are strong but short and form deep vertebral notches. This allows for better support and stability in the lower back, which is important due to the weight-bearing function of the lumbar spine.
The Knees are flexed during the AP Lumbar Spine to flatten the natural ________________________ curve of the spine.
During the AP Lumbar Spine, the knees are flexed to flatten the natural lordotic curve of the spine. The lordotic curve refers to the inward curve of the lower back. By flexing the knees, it helps to reduce the curvature of the lower back and create a more flattened position for the lumbar spine during the imaging procedure. This positioning allows for better visualization and assessment of the lumbar vertebrae and their alignment.
The Lumbar vertebrae are larger and stronger than the other vertebral segments.
The Lumbar vertebrae are larger and stronger than the other vertebral segments. This suggests that they have a greater ability to support and protect the spinal column. The increased size and strength of the Lumbar vertebrae may be due to their location in the lower back, where they bear more weight and experience more stress compared to other vertebral segments. This structural difference likely enhances the stability and functionality of the spinal column, making the statement true.
Broad, strong and short part located between the superior and inferior article process?
The lamina is a broad, strong and short part located between the superior and inferior articular process. It is flattened or arched part of the vertebral arch that helps from the posterior boundary of spinal canal. The lamina provides protection for the spinal cord and nerves that pass through the spinal canal. It also serves as an attachment point for muscles and ligaments.
Central ray is directed to the midcoronal plane at the level of the iliac crest for which Lumbar spine position.
The correct answer is Lateral Projection. In a lateral projection of the lumbar spine, the central ray is directed to the midcoronal plane at the level of the iliac crest. This positioning allows for a clear visualization of the lumbar vertebrae and their alignment. The lateral projection is commonly used to assess for spinal fractures, scoliosis and other abnormalities in the lumbar spine.
The conducting zone's role is to?
The conducting zone refers to the airways in the respiratory system that are responsible for conducting air into the lungs. It includes the nose, pharynx, larynx, trachea, bronchi and bronchioles. The conducting zone's role is no only limited to conducting air but also involves cleaning the air of debris, adding moisture to the air and warming the air before it reaches the lungs. Therefore, the correct answer is "All of the above"
Well defined, projecting from the junctions of the pedicles and laminae.
Articular processes are well defined and project from the junctions of the pedicles and laminae. These processes are found in the vertebrae and play a crucial role in the movement and stability of the spine. They form joints with adjacent vertebrae, allowing for flexion, extension, rotation and lateral bending of the spine. The description provided matches the characteristics of articular processes, making it the correct answer.
Wider transversely than dorsoventrally; deeper anteriorly then posteriorly and the superior and inferior surfaces are flattened or slightly concave.
The given answer, "Body", is correct because it accurately describes the characteristics of the structure being described in the question. The body is wider transversely than dorsoventrally, meaning it is broader from side to side than from front to back. It is also deeper anteriorly than posteriorly, meaning it is deeper towards the front than towards the back. Additionally, the superior and inferior surfaces of the body are flattened or slightly concave. Therefore, the body is the most appropriate answer based on the given description.
Which of the following is not part of the upper respiratory system?
The trachea is not part of the upper respiratory system. The upper respiratory
Triangular shape, formed anteriorly by the posterior surface of the body, laterally by the pedicles, posteriorly by the lamina and spinous process.
The vertebral foramen is the correct answer because it is described as being triangular in shape and formed by the posterior surface of the body, the pedicles, the lamina and the spinous process. This description matches the given explanation, making it the most fitting choice.
The nose connects with the pharynx through the?
The choanae are the openings at the back of the nasal cavity that connect it to the pharynx. Theses openings allow air to pass from the nose into the throat and eventually into the lungs. The septal cartilage, external nares, nasal meatuses and uvula are all structures within the nose, but they do not directly connect to the pharynx. Therefore, the correct answer is choanae.
