The word "Gomphosis" is a Greek-derived anatomical term used to describe the firm joint formed by the insertion of a tooth into the alveolus of the mandible or maxilla. This term is pronounced as [ɡɒmˈfoʊsɪs] according to the International Phonetic Alphabet (IPA) transcription. The spelling is derived from Greek roots, where "gompho-" means bolt or nail, and "-osis" indicates a condition or state. Thus, "gomphosis" refers to the state of being nailed or bolted, which accurately describes the firm and immovable joint formed by teeth and bone.
Gomphosis is a term used in anatomy and biology to describe a type of immovable joint or attachment between bones, specifically in the skeletal structure of the human body. The word "gomphosis" originates from the Greek word "gomphos," which means "nod" or "bolt."
In gomphosis, two bones are connected by a structure called a fibrous joint, also known as a syndesmosis, where the articulating surface of one bone fits into a socket or cavity of the other bone. However, unlike other types of joints such as synovial joints, gomphosis joints are completely inflexible and lack movement.
A prominent example of a gomphosis joint is the connection between the teeth and the sockets in the jawbone, known as the alveolar process. The root of each tooth fits into a specific socket or alveolus, with strong fibrous connective tissue called the periodontal ligament holding them firmly in place. This gomphosis joint provides stability and support for the teeth, allowing effective functions such as chewing and speaking.
Gomphosis joints are vital in ensuring structural integrity and stability in the skeletal framework of the body. They are enduring and fortified connections that withstand the forces exerted during various physical activities. Understanding and studying gomphosis is crucial in the field of anatomy, particularly in dental health, as it helps explain the attachment and function of teeth in the oral cavity.
Socket articulation; a form of synarthrosis (syndesmosis) in which a peg-like process fits into a hole, as the root of a tooth into the socket in the alveolus.

The word "gomphosis" has its origin in the Greek language. It is derived from the Greek word "gomphos" (γόμφος), meaning "a peg" or "a nail". The term was specifically used in Greek medicine to refer to a joint or articulation where a peg-like structure is inserted into a socket, forming a stable connection. In modern anatomical terminology, "gomphosis" continues to be used to describe a type of joint found in specific areas of the body, such as the teeth sockets in the jawbone.
