An example of this is the collateral ligaments of the knee. Therefore, joints can be classified in one of two main ways. This type of joint can be found between your neck vertebrae. It does appear able to be Abducted and Adducted as well as Rotated. These joints are divided into three categories, based on the number of axes of motion provided by each. To begin our investigation, let's focus on the pivot joints.

These joints offer a greater range of motion than other joint types. Cartilaginous joints are also functionally classified as either a synarthrosis or an amphiarthrosis joint. Hence, I'll introduce the youngest - or the little kid, so to speak - of the joint family. All synovial joints are functionally classified as diarthroses. A common example is a skull which is made up of a number of bones fused. A biaxial diarthrosis, such as the metacarpophalangeal joint, allows for movement along two planes or axes. Adduction —bringing an extremity toward the body.

They make the skeleton flexible — without them, movement would be impossible. The hip and shoulder joints are examples of a multiaxial diarthrosis. At a synovial joint, the articulating surfaces of the bones are not directly connected, but instead come into contact with each other within a joint cavity that is filled with a lubricating fluid. The lower leg to ankle joint and the forearm to wrist joint are the two main examples of gliding joints. Six Synovial Joints To guide you through the process of learning about these joints, take a look at this illustration.

Ball-and-socket joints are represented as letter F in our first illustration. These joints are found where the ribs attach to the breastbone and between some of the pelvic bones. Ligaments are essential to joint health; a stretch or tear to a ligament is usually called a sprain, while damage to a muscle or tendon is a strain. Muscles are attached to bones with thick, tough bands of connective tissue called tendons. When you decide to move, the motor cortex sends an electrical signal through the spinal cord and peripheral nerves to the muscles, making them contract. Joints are formed where bones come together.

Joints that allow for movements in two planes are biaxial joints, such as the metacarpophalangeal joints of the fingers. Types of Joints between bones in the human body Different types of joints enable the bones forming the joints to move relative to each other in different ways and to different extents, i. The bones in these joints fit together with a spherical bone sitting inside another bone that has a concave depression. There is also a layer of hyaline in the joint that again allows for smoother movement. A slightly moveable amphiarthrosis provides for small movements, which in the vertebral column can add together to yield a much larger overall movement. The epiphyseal growth plates are examples of synchondroses. The apparant rotation actually occurs in the Forearm and comes from Pronation and Suppination of the Radius and Ulna.

It is located between the first two vertebrae in the neck.

For instance, when you turn your head side-to-side, it's due to the rotary motion permissible in pivot joints. Diarthrosis The most freely movable joints, however, are called diarthrosis joints. Cartilaginous In a cartilaginous joint, the bones are united by fibrocartilage or hyaline cartilage. Immoveable joint Synarthrosis singular Synarthroses plural slightly moveable Bones held together by.

A biaxial joint allows for motions within two planes. Muscles can pull bones, but they can't push them back to the original position. There is no need to include examples unless asked for - but they may help students remember the joint types.
