What are the 3 main bones of the pelvic girdle, or pelvis?
ilium, ischium, and pubis, they are fused.
Muscle that attaches at the iliac crest?
iliocostalis and longissimus lumborum
Which bones of the pelvis girdle are the largest, most cranial and articulates with the sacrum?
ilium
Which bones of the pelvis are the most caudal?
ischium
Where does the pelvis unite mid-ventrally?
symphysis pubis
What is the name of the large foramen in the pelvis
obturator
What/where is the acetabulum?
ball and socket joint of the hip, it is where all 3 bones of the hip meet and receives the greater head of the femur
the pelvic canal is also called?
birth canal
the pelvic canal has 2 parts?
inlet and outlet
the lateral wall of the pelvic canal is made of what?
ilium, ischium, and pubis
Describe the wing of the ilium?
Smooth, flares at the cranial portion and then tapers down narrowly into the body caudally
The sharp corners of the ilium are referred to as its?
spine
What are the tuber sacrale?
cranial dorsal iliac spine and caudal dorsal iliac spine
What are the tuber coxae?
cranial ventral iliac spine and caudal ventral iliac spine
Which muscles attach to the wing of the ilium?
sartorius and middle gluteal muscles originate
The lateral aspect of the ilium has a depression or fossa that forms what surface? What muscles attach there?
gluteal surface;
1) middle gluteal muscle
2) deep gluteal muscle
the medial surface of the ilium is rough and articulates with the sacrum, what is this surface called?
sacropelvic surface
What/where is the arcuate line?
It is on the ventral, medial border on the body of the ilium and serves as the attachment for the psoas muscles (part of the iliopsoas muscle that helps the dog contract its hip and connects the lower spine to the thigh/femur)
How many bones make up the acetabulum at birth? When do they fuse?
4 bones, fuse at 3 months
Inherited orthopaedic condition where the soft tissues that support the hip are looser than normal and the muscles that support the hip are poorly developed. The head of the femur slips in and out (subluxation) and becomes flattened like a mushroom?
