Amphiarthrosis is a medical term that refers to a type of joint that allows only a limited amount of movement. The word is spelled with the prefix "amphi-", which means "both", and the suffix "-arthrosis", which means "joint". The "th" combination in the middle is pronounced like the "th" in "thin", as shown in the IPA phonetic transcription: /æmfiɑrˈθroʊsɪs/. While it may seem complex, the spelling and pronunciation of Amphiarthrosis follow the usual English rules for combining Greek roots and suffixes.
Amphiarthrosis is a term used in anatomy and orthopedics to describe a type of joint that allows limited movement. It is derived from the Greek words "amphi" meaning "both" or "on both sides," and "arthrosis" meaning "joint." Thus, amphiarthrosis refers to a joint that is partially movable.
In amphiarthrosis joints, the bones are connected by fibrous or cartilaginous tissue, such as ligaments or disks. These types of joints are designed to provide stability and to absorb shock, rather than for extensive movement. Examples of amphiarthrosis joints in the human body include the joints between the vertebrae in the spine and the pubic symphysis joint between the two pelvic bones.
Due to their limited mobility, amphiarthrosis joints provide essential support and protection to vulnerable structures, such as the spinal cord and internal organs. The fibrous or cartilaginous connections between the bones ensure that they remain securely connected while still allowing for slight movement.
Understanding the classification of joints, such as amphiarthrosis, is crucial in the fields of anatomy, orthopedics, and physical therapy. By recognizing the different types of joints and their respective functions, healthcare professionals can diagnose, treat, and rehabilitate joint-related disorders and injuries more effectively. Moreover, studying amphiarthrosis helps to comprehend the overall structure and mechanics of the human body.
Mixed articulation, half-joint; one in which the opposing ends of the bones, tipped with hyaline cartilage, are united by fibrous or fibrocartilaginous material, with an incomplete joint cavity in its center, allowing of partial movement; as the articulations of the bodies of the vertebrae.

The word "Amphiarthrosis" comes from the combination of two Greek roots: "amphi", meaning "on both sides" or "around", and "arthrosis", meaning "joint". "Amphi" is derived from the Greek word "amphí", which carries the sense of "on both sides". "Arthrosis" originates from the Greek word "arthrōsis", describing a "joint" or "articulation". Therefore, "Amphiarthrosis" can be translated as "joint on both sides" or "joint surrounded by something".
