Functions of Saddle Joints
Saddle joint allow the following functions:
- It allows the opposable thumb movement by enabling the thumb to touch other fingers for a precise grip.
- Allows flexion and abduction that is bending and straightening movements of the thumb.
- The incudomalleolar joint, located in the inner ear, connects the incus (anvil) and the malleus (hammer) bones. They are important for hearing and interpreting sounds.
- Saddle joints are biaxial joints, which means movement occurs at two distinct axes at right angles to each other. This allows for bending motions in several directions.
- Saddle joints can perform adduction, abduction, and circumduction movements.
Saddle Joints
The saddle joint is a type of synovial joint that allows a wide range of movements. movement in two planes. Joints are characterized by the presence of two reciprocal concave and convex surfaces, that allow movement in two planes. These planes are flexion/extension and abduction/adduction. In the human body, the saddle joint can be found in the carpometacarpal joint of the thumb, the incudomalleolar joint of the middle ear, the sternoclavicular joint of the thorax, and the calcaneocuboid joint of the heel.
