Anatomy Flashcards
Bones of the pelvic girdle
-Pelvic bone (Os Coxae) (L&R)
=Ilium
=Ischium
=Pubis
-Sacrum
-Coccyx
=Iliac fossa
=Iliac crest
=Arcuate line
=ASIS, AIIS, PSIS, PIIS
=Gluteal surface
=Gluteal lines
Features of Ischium
-Body of ischium
-Ischiopubic ramus
-Ischial spine
-Lesser sciatic notch
-Ischial tuberosity
Features of Pubis
-Body of pubis
-Superior ramus
-Inferior ramus
-Pectineal line
-Pubic tubercle
-Pubic crest
Features of the pelvic inlet
-Sacral promontory
-Margin of alae
-Arcuate line
-Pectineal line
Features of the pelvic outlet
-Tip of coccyx
-Sacrotuberous ligament
-Ischial tuberosity
-Ischiopubic ramus
What is the true pelvis?
Between the inlet and outlet
Joints of the pelvis
-Sacroiliac joint
-Pubic symphysis
-Lumbosacral
-Sacrococcygeal joint
Features of the sacroiliac joint
-Transmit forces from LL to vertebral column
-Synovial
-Limited mobility – interlocking surfaces
-Ossifies with age
Ligaments of the pelvis joints
-Anterior sacroiliac ligament
-Posterior sacroiliac ligament
-Interosseous sacroiliac ligament
Features of the pubic symphysis
-Fibrocartilaginous joint
-Hyaline cartilage covers bone
Ligaments of the pubic symphysis
-Superior and inferior
Features of lumbosacral joint
-L5 and Sacrum/S1
=2x zygapophyseal joints
=IV disk join
Ligaments of the lumbosacral joint
-Anterior longitudinal
-Iliolumbar
-Lumbosacral
Features of the sacrococcygeal joint
-Symphysis joint
-Hyaline and fibrous cartilage
-Very small amount of passive movement
Ligaments of the sacrococcygeal joint
-Anterior sacrococcygeal ligament
-Posterior sacrococcygeal ligament
=Superficial
=Deep
