Articulatio spheroidea
Articulatio Spheroidea is a type of synovial joint that allows for free movement in multiple directions. Also known as a ball-and-socket joint, it is one of the most mobile types of joints in the human body.
Structure[edit | edit source]
The articulatio spheroidea is composed of two parts: a spherical "ball" at the end of one bone, and a rounded "socket" in another bone. The ball fits into the socket, allowing for movement in multiple directions. The most notable examples of this type of joint are the hip joint and the shoulder joint.
Function[edit | edit source]
The primary function of the articulatio spheroidea is to allow for a wide range of movement. This includes flexion, extension, adduction, abduction, and rotation. This high degree of mobility comes at the cost of stability, making these joints more susceptible to dislocation.
Clinical Significance[edit | edit source]
Due to their high mobility and relative lack of stability, ball-and-socket joints are often the site of injuries and disorders. These can include osteoarthritis, rheumatoid arthritis, and various types of dislocations. Treatment for these conditions can range from physical therapy to surgical intervention.
