Pelvic Girdle

It is also known as the bony pelvis or pelvic girdle in human structure. It is a basin-shaped network of bones in the lower body that joins the trunk to the legs. It also houses and protects the digestive system, urine bladder, and internal sex organs as well.

Each of the two hip bones is made up of 3 bones: the blade-shaped ilium, above and also to either side, that accounts for the size and shape of the hips; the ischium, behind and below, under which the mass falls when sitting; as well as the pubis, in front. The pelvis is divided into two parts: the pubic symphysis, which connects the two hip bones; and the sacrum, which connects the two hip bones. During young adulthood, all three come together at a triangle sutures in the acetabulum, the cup-shaped socket which connects the head of the femur to the thigh bone (thighbone). Women give birth through a ring formed by their pelvis, which serves as a birth canal. Various muscles which stabilise as well as maintain the trunk, as well as those that move and rotate the legs, hips, and trunk, are attached to and function from the pelvis. The pelvis of a newborn infant is small and non supportive in nature.. During the first few months of a child’s walking, his or her pelvis becomes wider and tilted, the sacrum falls deeper into the ilia, and a lumbar curvature in the lower back forms.The abdominal organs are dependent on the vertebral column in semi erect apes, and the centre of gravity is located at the shoulder in these creatures as well.Because of the extended and spoon-shaped nature of the ilium, the pelvis is placed horizontally in the body.A human being is standing erect when the centre of gravity drops so over middle of the body, as well as the weight is transferred from the spinal column to the thigh bone, the knee, as well as the foot through the pelvis.

Pelvic girdle

Located in the lowest region of the trunk, the pelvic girdle is a ring-shaped bony structure that provides support for the lower section of the body. The axial skeleton is connected to the lower limbs through this structure.Two hip bones (furthermore called innominate or pelvic bones) are connected by a ligament that runs from one hip bone to the other. The sacrum and the coccyx are likewise connected by a ligament that runs from one hip bone to another.The sacroiliac joints are the joints that connect the ilium of the hip bones to the sacrum.The sacrococcygeal symphysis is the joint that connects the sacrum and the coccyx.

The pubic symphysis is the joint that connects the pubic bodies of the two hip bones.

Ligaments connect the lateral edge of the sacrum to different bone structures on the bony pelvis, which helps to maintain rigidity.With its sturdy and solid structure, the pelvis is well-suited for a variety of functions in the human body. The primary functions are in particular, during movement, weight is transferred from the top axial skeleton to the bottom appendicular elements of the skeleton.

Several muscles and ligaments that are involved in movement are attached to it.

The viscera of the abdominopelvic and pelvic regions are contained and protected by this organ.

Pelvic girdle bones

The hip bone, commonly referred to as the pelvic girdle, is an unevenly formed bone that connects the upper and lower bodies of an individual. The ilium, ischium, and pubis are the three bones that make up the thigh bone. The innominate bones, pelvic bones, and coxal bones are all names for the same three bones. It is primarily through the development of one another and are only joined by cartilage when they are in children’s developing bodies. The hip bone is divided into 2 portions (lateral and medial) and is bordered by 4 borders (anterior, posterior, superior and inferior).

There is an acetabulum (a prominent landmark on the bone’s lateral side), which is located on this surface. Hip bone expresses with femur through a socket-shaped articular surface, which results in the formation of a hip joint. Hip bone acetabular margin, which is intensified inferiorly by the cartilaginous acetabular labrum and finished superiorly by the transverse acetabular ligament, is a “C”-shaped margin of the acetabulum. Anatomically, the acetabulum is the primary resonance point of three bones which are organised in a specific manner inside its confines; it is also the most mobile of the three bones.

  • Due to the fact that it spreads to the anterior part to the hip joint, the ilium is considered to be the superior component of the acetabulum.
  • It is the enormous posteroinferior section of the hip bone that fits into the posteroinferior portion of the acetabulum, that’s why it is called the “ischium.”
  • When combined with the contralateral hip bone, the pubic bone forms the anterior inferior third of the acetabulum, which is the anteroinferior portion of the acetabulum that articulates with the hip bone.
  • The obturator foramen is yet another key feature on the hip bone. Ischium and pubis form a border around this wide aperture that is placed anterior inferior to the acetabulum. A communication channel between both the pelvic and thigh areas, the obturator foramen allows neurovascular systems to flow through.

Conclusion

Because the pelvis is a set of fused bones, it is often referred to as the “first step” in the process of connecting the axial skeleton (bones of the head, neck, and vertebrae) to the lower appendages. In the axial skeleton, the lumbar spinal column is the portion of the skeleton that communicates directly with the pelvis. When the femur is linked to the pelvis, it is called an acetabulum, which is created by the merging of 3 bones: the pubis, the ilium, and ischium. The pubis is a small bone that is attached to the femur by a bony ring called an acetabulum. In addition to providing connection sites for muscles, tendons, and ligaments, the pelvis serves as a primary support structure for movement.
