Sacrum Flashcards
What is the shape of the sacrum?
Pyramid
The sacrum has a unique pyramidal shape which contributes to its function and stability.
The vertebral column intersects with what at the sacrum?
Lumbar
Specifically, the sacrum connects with the 5th lumbar vertebra.
What is unique about the five vertebrae that make up the sacrum?
They are fused
The five sacral vertebrae are fused together, which distinguishes them from other vertebrae.
What is the degree of curvature of the sacrum?
About the same as lumbar curvature
The sacrum’s curvature is concave and faces anteriorly.
The superior sacrum interfaces with which vertebra?
5th lumbar
This interface is crucial for the stability of the lower back.
What lies at the distal end of the sacrum?
Coccyx
The coccyx, or tailbone, is the final segment of the vertebral column.
What is the controversy regarding the sacral joint?
Whether it moves
The debate centers around the mobility of the sacroiliac joint.
What is the approximate angle of the sacrum?
30 degrees
This angle plays a role in the biomechanics of the pelvis.
Is the neutral position of the sacrum vertical when standing?
No
The sacrum is not in a vertical position when a person is standing.
What is the major function of the sacroiliac joint?
Stability
The sacroiliac joint is crucial for maintaining pelvic stability.
What happens when the bones of the sacroiliac joint are no longer neutral?
Ligaments are stressed
This stress can lead to pain or discomfort in the area.
How does the design of the sacrum create stability?
The shape creates a wedge
This wedge shape is integral for the stability of the pelvic region.
Is it important to not overstretch the ligaments of the sacroiliac joint when performing asanas?
Yes
Overstretching can lead to permanent changes in ligament length and stability.
