What are the four bones that make up the pelvis?

The right and left hip bones, the sacrum, and the coccyx.

What is the primary function of the pelvis when standing?

To transfer the weight of the upper body to the lower limbs.

Which structures does the pelvic cavity primarily contain?

The reproductive organs, the rectum, and parts of the urinary system.

What are the components of the bony pelvis?

The pelvic girdle (hip bones, sacrum, and coccyx) and the pelvic spine.

Which two bones form the pelvic spine?

The sacrum and the coccyx.

What is the function of the sacroiliac joints (SIJs)?

They transfer forces between the spine and pelvis, allowing slight movement for stability.

How does the coccyx contribute to pelvic stability?

It serves as an attachment point for pelvic floor muscles and helps with balance when sitting.

Which three fused bones form each hip bone?

The ilium, ischium, and pubis.

What is the function of the acetabulum?

It forms the hip joint with the femur, allowing movement and weight-bearing.

Where is the iliac crest located, and why is it clinically significant?

It is the upper border of the ilium, serving as a landmark for locating the L4-L5 vertebrae.

What are the four major protrusions of the ilium?

The anterior superior iliac spine (ASIS), anterior inferior iliac spine (AIIS), posterior superior iliac spine (PSIS), and posterior inferior iliac spine (PIIS).

What is the importance of the anterior superior iliac spine (ASIS)?

It is a key landmark for evaluating pelvic symmetry and serves as an attachment point for the inguinal ligament.

Which structure allows for the passage of nerves and blood vessels from the pelvis to the lower limbs?

The greater sciatic notch.

Why is the ischial tuberosity commonly referred to as the "sit bone"?

It supports body weight when sitting.

What is the role of the pubic symphysis in pelvic stability?

It acts as a shock absorber during movements and provides slight mobility for posture adjustments and childbirth.

What is the function of the greater trochanter?

It serves as an attachment site for muscles involved in hip stability and movement.

What are the main functions of the pelvis?

Weight-bearing, organ protection, movement facilitation, and childbirth support.

How does the pelvis contribute to movement?

It connects the spine and lower limbs, allowing hip joint mobility for walking and running.
