joints and ligaments Flashcards
1
Q
ligaments of sacroiliac joint
A
- anterior sacroiliac
- interosseous and posterior sacroiliac ligaments
- sacrospinous ligament
- sacrotuberous ligament
2
Q
anterior sacroiliac ligament
A
- anterior part of fibrous synovial capsule to auricular surfaces of sacrum and ilium
3
Q
interosseous and posterior sacroiliac ligaments
A
- from tuberosity and posterior surface of sacrum to tuberosity of ilium
- transfer body weight from sacrum to hips
4
Q
parts of sacroiliac joint
A
- anterior synovial joint
- posterior syndesmosis
5
Q
anterior synovial joint of sacroiliac
A
- auricular surfaces of sacrum and ilium
6
Q
posterior syndesmosis
A
- sacral tuberosity to iliac tuberosity
- interosseous and posterior sacroiliac fibers are the syndesmosis
7
Q
movements of sacroiliac joint
A
- nutation/counternutation
8
Q
sacrospinous ligament
A
- from posterior surface of sacrum and coccyx to ischial spine
- prevents excessive anterior rotation (nutation of sacrum)
9
Q
sacrotuberous ligament
A
- from posterior surface of sacrum and coccyx to ischial tuberosity
- prevents excessive anterior rotation (nutation of sacrum)
10
Q
pubic symphysis
A
- secondary cartilaginous
- fibrocartilage interpubic disc
- articulation of 2 symphysial surfaces of pubic bones with fibrocartilage disc
- movement: none except during childbirth
11
Q
sacrococcygeal symphysis
A
- secondary cartilaginous joint with an intervertebral disc
- apex of sacrum with base of coccyx
- movement: none except during childbirth (coccyx moves posteriorly)
12
Q
hip joint
A
- ball and socket
- articular surface of acetabulum with head of femur
- movement:
- flexion/extension
- abduction/adduction
- circumduction
- rotation
13
Q
ligaments of hip joint
A
- iliofemoral
- pubofemoral
- ischiofemoral
14
Q
iliofemoral ligament
A
- located anterior and superior to joint
- attaches from acetabular rim of ilium to intertrochanteric line
15
Q
pubofemoral ligament
A
- located anterior and inferior to joint
- attaches from superior rams of pubic bone to joint capsule and iliofemoral ligament
