Pelvic girdle
Obturator foramen
A portion of each pubis passes posteriorly and downward to join an ischium. Between the bodies of these bones on either side is a large opening, the obturator foramen, which is the largest foramen in the skeleton.
Inferior pubic ramus
Connects to the ischial ramus.
Pubis
Constitutes the anterior portion of the hip bone. The two pubic bones come together at the midline to form a joint called the pubic symphysis.
Hip bones
Each hip bone develops from three parts-an ilium , an ischium, and a pubis
True pelvis
Inferior to the pelvic brim, the true pelvis is bounded posteriorly by the sacrum and coccyx and laterally and anteriorly by the lower ilium, ischium, and pubis bones. This portion of the pelvis surrounds a short, canal-like cavity. The superior opening of the cavity, the pelvic inlet, is at the boundary between the true and false pelves.
Lesser sciatic notch
Semicircular depression inferior to the ischial spine.
Iliac crest
Superior most ridge of the Ilium.
false pelvis
Superior to the pelvic brim, the false pelvis is bounded posteriorly by the lumbar vertebrae, laterally by the flared parts of the iliac bones, and anteriorly by the abdominal wall. The false pelvis helps support the abdominal organs.
pelvis
The sacrum,coccyx, and pelvic girdle form the bowl- shaped pelvis. The pelvic girdle supports the trunk of the body; provides attachments for the lower limbs; and protects the urinary bladder, the distal end of the large intestine, and the internal reproductive organs. The body's weight is transmitted through the pelvic girdle to the lower limbs and then into the ground.
Iliac fossa
The smooth, concave surface on the anterior aspect of the ilium is the iliac fossa.
Pubic symphysis
The two pubic bones come together at the midline to form a joint called the pubic symphysis.
Acetabulum
These parts fuse inn a cup shaped cavity called the acetabulum. This depression on the lateral surface of the hip bone, receives the rounded head of the femur or though bone.
Pelvic brim
This margin separates the lower, or lesser (true), pelvis from the upper, or greater (false), pelvis.
Pubic arch
Two pubic bones come together at the midline to form a joint called the pubic symphysis. The angle these bones form below the symphysis is the pubic arch.
pelvic girdle
consists of two hip bones also known as coal bones ( ossa coxae), pelvic bones or innominate bones, which articulate with each other anteriorly and with the sacrum posteriorly.
Ischial ramus
extends from the ischial tuberosity toward its anterior fusion with the pubis.
Anterior Inferior Iliac Spine
located inferior to the ala of the ileum.
anterior superior iliac spine
located inferior to the ala of the ilium.
Greater sciatic notch
passage way for sciatic nerve.
Ischial tuberosity
roughened projection on posterior posterolateral border of ischium ("sit bones").
ilium
the ilium, the largest part and most superior portion of the hip bone, flares outward, forming the prominence of the hip.
Ischial spine
triangular projection posterior to acetebulum
