The posterior of the pelvis is better protected than the anterior due to the presence of the sacrum and the coccyx, which form a sturdy bony structure, along with the strong ligaments and muscles of the pelvic floor. These structures provide a robust defense against impacts and forces that could potentially injure the pelvic organs. In contrast, the anterior pelvis is more exposed and less reinforced, making it more vulnerable to trauma and injury. Additionally, the orientation of the pelvic bones allows for better absorption of forces from the back than from the front.

What ligaments extend from the lateral surface of the uterus to the anterior surface of the sacrum?
The broad ligament attaches the uterus to the walls and floor of the pelvis.
Can the ischial tuberosity be seen on the posterior side of the skeleton?
Yes, the ischial tuberosity is located on the posterior aspect of the pelvis. It is the bony prominence that you can feel when you sit down and is an attachment site for various muscles in the buttocks and thighs.
What structure is found posterior to the renal vascular pedicle?
The renal hilum is a structure found posterior to the renal vascular pedicle. It is the area where the renal artery enters and the renal vein and ureter exit the kidney.
What is the structure that contains a network of axons from several anterior rami is known as?
A plexus is the structure that contains a network of axons from several anterior rami. Examples include the brachial plexus in the arm and the lumbosacral plexus in the lower back and pelvis.
What permits passage of the sciatic nerve?
The sciatic nerve passes through the greater sciatic foramen, which is an opening in the pelvis formed by the ilium, ischium, and sacrum. It typically exits the pelvis below the piriformis muscle, although variations exist where it can sometimes pass above or through the muscle. This pathway allows the nerve to travel down the posterior aspect of the thigh and into the leg.
What are the key differences between anterior and posterior structures in the human body?
Anterior structures in the human body are located towards the front, while posterior structures are towards the back. Anterior structures are often involved in functions like breathing and digestion, while posterior structures are more related to support and protection, such as the spine and pelvis.
What attaches to the posterior part of the pelvis?
coccyx
What is the name of the dorsal posterior pelvis?
ischium
What is the posterior part of the pelvis?
"spinus process"
What is the significance of gynecoid pelvis?
The gynecoid pelvis is the most common pelvis shape in females, facilitating childbirth by providing ample space for the passage of the baby's head. Its wide and round shape is favorable for vaginal delivery compared to other pelvis types. The significance lies in its ability to reduce complications during labor and delivery.
What is the posterior pelvis?
The posterior pelvis refers to the back part of the pelvis, which includes the sacrum, coccyx, and the back of the hip bones (ilium). It provides support and protection for the pelvic organs and allows for the attachment of muscles and ligaments involved in movement and stability.
An anterior tilt of the pelvis is common with the postural deviation scoliosis?
false
What is the difference of a hominid's pelvis and a quadruped's pelvis?
Hominid pelvis is bowl shaped while a quadruped pelvis is wider because of the way the internal organs are carried and protected.
What is the origin and insertion of the gluteus maximus?
Origin: the gluteus maximus originates from the posterior inferior surface of the sacrum and coccyx, and the posterior medial surface of the ilium.Insertion: the gluteus maximus inserts into the gluteal tuberosity on the posterior aspect of the femur, and the anterior aspect of the lateral tibial condyle.
What does anterior mean in pregnancy?
It means that the baby is facing the mothers pelvis during pregnancy or labor.
What is the point of the pelvis protruding out anteriorly just above your thigh?
anterior superior iliac spine
What ligaments extend from the lateral surface of the uterus to the anterior surface of the sacrum?
