Anatomy & Physiology Articulations (Joints)
Joints can be completely immovable (synarthrosis); slightly movable (amphiarthrosis); or freely movable (synovial or diarthrosis). Immovable joints connect the parts of the skull at the sutures and connect the teeth to the jaw at the gomphoses. Partially movable joints include the connections between the ribs that allow for expansion when breathing. Types of slightly movable amphiarthroses include syndesmosis and symphysis. Synovial joints include elbows, knees, and knuckles. They contain articular cartilage, joint capsules, synovial membranes, bursae, spongy/compact bone, and a periosteum. Synovial joint movement can be described as flexion/extension as well as abduction/adduction, supination/pronation, depression/elevation, retraction/protraction, and circumduction. Types of synovial joints include hinges, pivots, gliding, ellipsoid, saddle, and ball and socket. Joint disorders include arthritis, bunions, bursitis, dislocations, and hyperextensions. This lecture also includes the anatomy of the knee.

I am double-jointed, but when I feel my arm, there seems to be a split and a second joint. The joint area is also significantly wider than others that are my age. Can you explain this scenario?

How does a person become "double jointed", being able to push bend an arm over 180 degrees, and what is actually going on.
