Osterizer Imperial Viii Model 542

The lower member comprises four segments: the girdle (waist) pelvic, femoral region (thigh), leg and foot.

pelvic girdle

It consists of two iliac or innominate bones, articulated with the sacrum behind and joined together before the pubic symphysis.

the innominate bone is a pair, articulated, then to the sacrum, below and in the median line with his counterpart, down and laterally with the coxal fémur.Cada consists of three separate bones: the ilium, ischium and pubis. In the early years of the three bones are separated, but later fuse and form a single structure, ie a single bone, which shows two faces, four edges and four corners ..

cavity formed by this belt, serves as shelter to the intestines, rectum, bladder and internal reproductive organs.

It is noteworthy that in women the pelvic bones is formed by light, which facilitates the placement of the uterus during pregnancy and expansion in the output of the fetus at delivery.

lateral

- or acetabulum Acetabulum. It is a rounded cavity, deep, consists of a circular flange outgoing edge acetabular acetabulum eyebrow. Acetabular notch. The acetabulum has two distinct parts: a non-articular (bottom of the cup) in a quadrilateral, its lower edge corresponds to the acetabular notch. the other is to articulate fascie lunata.

above the acetabulum

expands gluteal face reveals two rough: gluteal line anterior and posterior gluteal line.

medial or internal

A ridge run from top to bottom and from back to front, the arcuate line (unnamed) divide this face into two:

-superolateral is the iliac fossa (internal), as one looks back the foramen (holes) nutrient bone, down and sideways dirijiso

-Below and behind is on, from top to bottom: iliac tuberosity, roughness intended for the insertion of the posterior sacroiliac ligaments, auricular face; quadrilateral surface
