Pelvic Girdle Flashcards
Pelvic girdle is the point where
The lower limb attaches to the trunk of the body
Bony pelvis includes what three bones
Pelvic bone, sacrum, coccyx
Pelvic bone is a fusion of three separate bones including
Ilium, ischium, and pubis
Where do the three pelvic bones join and articulate
They join in the acetabulum, a cup shaped feature for articulation with the head of the femur aka thigh bone
Posterior and anterior articulations of the pelvic bones (left and right)
Pelvic bones articulate with the sacrum posterior lumbar and at the pubic symphysis anteriorly
Sacrum
A fusion of five sacral vertebrae of the spine
Coccyx
The terminal end of the spine and a remnant of our embryonic tail
Characteristics of the coxal (hip) bone
Fusion of three bones on each side to form the pelvis, which articulates with the sacrum to form the pelvic girdle
Characteristics of illium
Body fused to ischium and pubis, all meeting in the acetabulum (socket for articulation with femoral head)
Illium ala
“Wing” ; weak spot of ilium
Ischium charact.
Body fused with other two bones; ramus fused with pubis
Pubis
Body fused with other two bones; ramus fused with ischium
Femoral long bone
Longest bone in the body and very strong
Femoral head
Point of articulation with acetabulum of coxal bone
Aka for coxal bone
Hip bone
