A joint, also called an articulation, is any place where adjacent bones or bone and cartilage come together (articulate with each other) to form a connection. Joints are classified both structurally and functionally.
Based on the shape of the articulating bone surfaces and the types of movement allowed, synovial joints are classified into six types. At a pivot joint, one bone is held within a ring by a ligament and its articulation with a second bone. Pivot joints only allow for rotation around a single axis.
The different types of movement that are permitted at each joint are described below. Flexion – bending a joint. This occurs when the angle of a joint decreases.
7 Σεπ 2024 · A joint is defined as a connection between two bones in the skeletal system. Joints can be classified by the type of the tissue present (fibrous, cartilaginous or synovial), or by the degree of movement permitted (synarthrosis, amphiarthrosis or diarthrosis). In this article, we shall look at the classification of joints in the human body.
The six types of synovial joints are pivot, hinge, condyloid, saddle, plane (gliding), and ball-and socket-joints (Figure 11.8). 1. Pivot Joint: At a pivot joint, a rounded portion of a bone is enclosed within a ring formed partially by the articulation with another bone and partially by a ligament (Figure 11.8a).
This section will examine the anatomy of selected synovial joints of the body. Anatomical names for most joints are derived from the names of the bones that articulate at that joint, although some joints, such as the elbow, hip, and knee joints are exceptions to this general naming scheme.
