An Introduction to Joint

posted by Malachy P. McHugh

The Shoulder Joint: The shoulder actually comprises several joints, with the main joint being the glenohumeral joint. The glenohumeral joint has minimal bony or ligamentous constraints, and a large range of movement in all 6 rotary motions.

The Elbow Joint: The elbow is a hinge joint with large flexion-extension and internal rotation- external rotation motions, but minimal abduction-adduction motion.

The Hip Joint: The hip joint is a large ball and socket joint that can move in all six rotary motions.

The Knee Joint: The knee is the largest joint in the body. It is a modified hinge joint with significant flexion-extension motion, but very limited internal rotation-external rotation motion and minimal abduction-adduction motion.

The Ankle Joint: The functional motion of the ankle joint is best considered in association with the foot rather than as a single distinct joint. The foot and ankle are coupled and cannot be precisely categorized as abduction-adduction, internal rotation-external rotation. But, for simplicity, these terms are used.

  • I'm trying to add a workout today and I can only add targeted and the site won't let me add actual, so it shows no calories burned today, any ideas?
    Thanks, houstonbrenda
