Step 1: Begin by understanding the classification of joints in the human body. Joints are categorized into three main types based on their structure and function: fibrous joints, cartilaginous joints, and synovial joints.
Step 2: Learn about fibrous joints. These joints are connected by dense connective tissue and do not have a joint cavity. They are typically immovable or only slightly movable.
Step 3: Examine the specific types of fibrous joints: sutures, gomphoses, and syndesmoses. Sutures are found between the bones of the skull, gomphoses are the joints between teeth and their sockets, and syndesmoses are joints where bones are connected by ligaments (e.g., the distal tibiofibular joint).
Step 4: Compare fibrous joints to other types of joints. Cartilaginous joints are connected by cartilage, and synovial joints have a fluid-filled cavity that allows for free movement. This distinction helps clarify why sutures, gomphoses, and syndesmoses are classified as fibrous joints.
Step 5: Conclude that sutures, gomphoses, and syndesmoses share the common characteristic of being fibrous joints, which are defined by their connective tissue structure and limited mobility.
