Some are relatively immobile but more stable than mobile joints. They are also known as either arthrodial joints or plane joints, and usually occur between flat bones that need to slide past each other in order to allow the desired motion. The movement i. The primary places in the human body that you will find gliding joints are in the ankles, wrist, and spine. Below is a description of the different types of gliding joints.
There are several gliding joints located in the ankles. The main one located in the ankle is found where the two bones in the bottom part of your leg, the fibula and tibia, and the tarsal bones in your foot meet. There are also other gliding joints located between the tarsal bones as well.
There are even more gliding joints located in the wrist. The wrist is made up of two layers of carpal bones. The first layer of carpal bones, which sits closest to the fingers, is made up of the trapezoid, trapezium, hamate, and capitate bones. Two sets of gliding joints in the thoracic region — one set between the sternum breast bone and ribs at the sternocostal joints, and the other between the vertebrae and ribs at the vertebrocostal joints — permit the ribs to elevate and depress slightly and change the volume of the thoracic cavity.
These slight rib movements are necessary to perform the vital process of breathing. Another set of gliding joints is found between the facets of the twenty-six vertebrae at the intervertebral joints.
