Front 1

Pelvis

Back 1

Transition between trunk and lower limbs

Front 2

Pelvic cavity

Area of trunk between thighs and buttocks, from publis to coccyx

Front 4

Perineum

Back 4

Shallow compartment

Front 5

Pelvic girdle

Back 5

1. Right and left hip bones (form at puberty from ilium, ischium, publis)

2. Sacrum (five fused vertebrae)

Front 6

Sacro iliac joints

Where sacrum and hip bones are joined

Forms a ring called the pelvis girdle

Front 7

Ala

Back 7

"Wings"

Wide part of ilium

Front 8

Pelvic girdle 3 functions

Back 8

1. Transfer weight of upper body from axial to appendicular skeleton

2. Withstand compression from support of body weight

3. Protect the pelvic viscera (including gravis uterus)
