The pelvis is composed of

The ________ is the deep depression on the surface of the hip bone which articulates the head of the femur

Runs downward and forward around the inner surface of the ilium and serves to divide the false from the true pelvis

Large opening on the lower part of the hip bone

What bones fuse to form the innominate bones

What arteries enter the pelvic cavity

Cartilaginous joint between the two pubic bones in the medial plane

Coccyx consist of 4 vertebrae fuse together to form a small triangular bone, which articulates at its base with the lower end of the sacrum

Sacrum consist of 5 rudimentary vertebrae fused together to form a single wedge shaped bone with a forward concavity

Sacrum is usually wider in proportion to its length in male than in female

The laminae in 5th sacral vertebra and sometimes those of the 4th fail to meet in the midline, forming the ___________.

Identify the structures

Identify the structures

Arises from the front of the lateral mass of the sacrum and leaves the pelvis to enter the gluteal region by passing laterally through the greater sciatic foramen

Behind the acetabulum is a large notch called

Runs between the anterior and posterior superior iliac spines

Triangle shaped

It is attached by its base to the lateral part of the sacrum and coccyx and by its apex to the spine of the ischium

Extends from the lateral part of the sacrum and coccyx and the posterior inferior iliac spine to the ischial tuberosity

Fibrous sheet that almost completely closes the obturator foramen, leaving a small gap, the obturator canal, for the passage of the obturator nerve and vessel as they leave the pelvis to enter the thigh

Arises from the pelvic surface of the obturator membrane and the adjoining part of the hip bone

Origin of piriformis

Insertion of piriformis

Origin of coccygeus

Lines the pelvic walls and is regionally named according to the muscle it overlies

Covers all the pelvic viscera

Lies on the posterior pelvic wall in front of the piriformis muscle

Formed from the part of the anterior ramus of the 4th lumbar nerve emerging from the medial border of the psoas muscle and joining the anterior ramus of the 5th lumbar nerve

Branch of the lumbar plexus (L1,L3, L4) accompanies the lumbosacral trunk into the pelvis

Ends at the pelvis inlet in front of the sacroiliac joint by dividing into the external and internal iliac arteries

Runs along the medial border of the psoas muscle and gives off the inferior epigastric and deep circumflex iliac branches

The branches of this division supply the pelvic viscera, perineum, pelvic walls, and buttocks

Direct continuation of the inferior mesenteric artery

Supplies the mucous membrane of the rectum and the upper half of the anal canal

Arises from the abdominal part of the aorta at the level of the 1st lumbar vertebra

Descends over the anterior surface of the sacrum and the coccyx

Veins of the pelvis

The stronger muscle in the male are responsible for the thicker bones and more prominent bony markings

45% in women; typical female pelvis

Male or funnel shaped pelvis with a contracted outlet

2% of women; wide pelvis flattened at the brim, with the promontory of the sacrum pushed forward

24% in white, 41% in black ; long narrow and oval shaped
