Overview of joint types: fibrous, cartilaginous: fibrocartilage, synovial: Synovial joints, hip low mobility some mobility fibrous connective tissue hyaline cartilage, high mobility several components, below: introduction to synovial joints, components, constant capsule slow to heal meniscus. Synovial cavity has no blood supply; nourished by synovial fluid: optional. Fibrocartilage (deepen cavity, promote sliding): labrum, disk, Intracapsular tendon (does not actually contact synovial fluid) Bursa(e) (facilitate movement of tendons over joint, independent or connected: joint motions. Flexion/extension: flexor is anterior, extensor is posterior. Abduction/adduction: abductor is lateral, adductor is medial. Rotation: internal rotator is anterior, external rotator is posterior. Review of pelvis (see also lecture 11 on pelvis and perineum from thorax/abdomen) Innominate (os coxae): ilium, ischium, pubis and associated features. Three bones ossify separately, fuse in early 20"s: bones. Sacroiliac (synovial) and ventral/dorsal sacroiliac, interosseous, sacrotuberous, sacrospinous ligaments. Pubic symphysis (cartilaginous) and superior/inferior pubic ligaments. Important in understanding transfer of body weight.
