  1. ANATOMY II.COMMITEE

  2. JOINTS OF VERTEBRAL COLUMN • symphyses between vertebral bodies • (n=2 one above, and one below) • synovial joints between articular processes • (n=4, two above and two below)

  4. Inferiorarticularprocess Plane . Superiorarticularprocess

  5. Uncovertebral joints (Luschka’s JOINTS) Unciof the bodies of C3 or 4C6 or 7 vertebrae .

  6. between the laminae of adjacent vertebrae . tectorial membrane

  7. Atlanto-occipital Yes, nodding+lateralflexion & rotation condyloid connects the anterior arch of the atlas to the anterior margin of the foramen magnum. . connects the posterior arch of the atlas to the posterior margin of the foramen magnum. Anterior/Posterioratlanto-occipital membranes

  16. Weight from the axial skeleton: Sacroiliac ligaments ilia Femurs –during standing- Ischial tuberosities –during sitting- Sacrum is actually suspended between the iliac bones Firmly attached to iliac bones by posterior and interosseous sacroiliac ligaments.

  17. male or funnel-shaped pelvis with a contracted outlet long, narrow, and oval shaped 41% of women widepelvis 2% of women

  18. Diagonal conjugate (from inferior pubic lig. to promontory) Measured by palpating sacral promontory with the tip of the middle finger, using the other hand to mark the level of the inferior margin of the pubic symphysis on the examining hand. After the examining hand is withdrawn, the distance between the tip of the index finger (1.5 cm shorter than the middle finger) and the marked level of the pubic symphysis is measured to estimate the true conjugate, which should be 11.0 cm or greater.
