The specific anatomic features of a joint play a large role in determining its range of motion, degrees of freedom, and overall functional potential. This chapter is intended to provide an overview of the basic structure and function of joints as a foundation for understanding the motion of individual body segments and the body as a whole.
The Meniscus. Another form of added protection in some joints, namely the knee joint, is a structure called a meniscus, which is a structure made out of fibrous cartilage that reduces the friction ...
Classification of Joints on the Basis of Structure and Function. The point at which two or more bones meet is called a joint or articulation. Joints are responsible for movement (e.g., the movement of limbs) and stability (e.g.,the stability found in the bones of the skull).
Structure and Function of Joints. ... The fibrous capsule, for mo st joints, is a firm structure consisting of . dense connective tissue that invests the entire joint and usually inserts into the ...
Arthrology, the study of the classification, structure, and function of joints, is an important foundation for the overall study of kinesiology. Aging, long-term immobilization, trauma, and disease all affect the structure and ultimate function of joints. These factors also significantly influence the quality and quantity of human movement.
Synovial joints have a space between the articulating bones that is filled with synovial fluid. This enables the articulating bones to move freely relative to each other. The structure of synovial joints is important for students of human anatomy e.g. following courses in A-Level Human Biology, ITEC Anatomy & Physiology, Nursing and many therapies.
The structure and function of synovial joints is our second dash point under the skeletal system. The skeletal system has a number of different joint types, for example there are fibrous joints and there are cartilaginous joints.
A joint is defined as the juncture where two or more bones come together for the purpose of movement or for stability. Contraction of muscles crossing the joint causes it to move. Normal joint function is defined as a joint's ability to move throughout its range of motion, bear weight and perform work.
Structure of a Synovial Joint. Although the exact structure of a synovial joint may vary depending on the function of the joint and the animal it is in, the general structure of each joint is the same. Extending from the periosteum of the bone, an articular capsulemade of cartilage and other fibers encapsulates the entire joint.
Joints hold the skeleton together and support movement. There are two ways to categorize joints. The first is by joint function, also referred to as range of motion. The second way to categorize joints is by the material that holds the bones of the joints together; that is an organization of joints by structure.
