The word "amphidiarthrosis" is a mouthful to spell, and its pronunciation can be even trickier for non-experts. Transcribed in IPA phonetic symbols, it reads /æm.fi.di.ɑr.ˈθro.sɪs/, which breaks down to "am" as in "amazing," "phi" as in "philosophy," "di" as in "digit," "ar" as in "arm," "thro" as in "throw," and "sis" as in "sister." This term refers to a type of joint in which two bones are connected by hyaline cartilage, such as in the vertebral column.
Amphidiarthrosis is a term used in the field of anatomy and physiology to describe a specific type of joint found in the human body. It refers to a type of articulation where two bones are connected by a fibrocartilaginous disc, allowing a limited amount of movement. This joint type is also commonly referred to as a symphysis joint.
Amphidiarthrosis joints can be found in various locations throughout the body, including the pubic symphysis in the pelvis and the intervertebral discs in the spinal column. These joints are characterized by the presence of a shock-absorbing layer of fibrocartilage between the articulating surfaces of the bones. This fibrocartilaginous disc helps to distribute forces and cushion the joint during movement.
Unlike other types of joints that allow a wide range of motion, amphidiarthrosis joints are classified as slightly movable or semi-rigid joints. This means that while some limited movement is possible, their primary function is to provide stability and support to the associated bones, rather than facilitating extensive motion.
Amphidiarthrosis joints are crucial for maintaining the structural integrity and flexibility of the body. They allow for minimal movement while providing stability and protection to important structures. By absorbing shock and preventing excessive movement, these joints help to reduce the risk of injury and ensure proper functioning of the affected anatomical regions.
A form of articulation combining amphiarthrosis and diarthrosis, as that of the mandible or lower jaw.

The word "amphidiarthrosis" is derived from Greek roots.
- "Amphi" (ἀμφί) translates to "on both sides" or "on both ends".
- "Diarthrosis" (διάρθρωσις) refers to "articulation" or "joint".
Therefore, the word "amphidiarthrosis" is a combination of these two roots, indicating a type of joint that connects bones on both ends.
