How is the sacrococcygeal joint reinforced?
Press to flip
By anterior and posterior sacrococcygeal ligaments.
Name two outcomes of posterior pelvic tilt.
Flattened lumbar curve and caused by trunk flexors and hip extensors.
In which joint does the pelvis join the axial skeleton with the appendicular skeleton?
At the sacrum
Identify the main functions of the lower extremity.
Carries body weight, maintains balance in standing and sitting positions.
Which joint expands during childbirth?
The Pubic Symphysis
What is the pelvic structure sometimes referred to as?
The lumbo-pelvic complex
What are the components of the Lumbosacral joint and why is it significant?
Consists of L5-S1 and is commonly affected by lumbar spinal disorders.
Which pelvic landmark is aligned with the ASIS in the neutral position?
The pubic symphysis
Describe 'anterior tilt' of the pelvis and its common causes.
ASIS is in front of the pubic symphysis with increased lumbar lordosis, caused by trunk extensors and hip flexors, common in late-stage pregnancy.
Explain the importance of the Sacroiliac (SI) joint.
Transfers weight between femur and axial skeleton, critical for movement and weight distribution.
Which bones constitute the pelvis?
Two ilium bones, two ischium bones, two pubic bones, sacrum, coccyx.
What clinical issue can arise from tight hip extensors?
Posterior tilt and reduced lumbar lordosis.
What can result from a lateral tilt of the pelvis?
Can result in scoliosis and impacts balance.
Name three key functions of the pelvis.
Provides bony protection for internal organs, passageway for GI and GU systems, attachment site for trunk and lower extremity muscles.
What landmark on the ischium serves as the attachment site for the hamstring and adductor magnus?
Ischial Tuberosity
