Syndesmoses5 (SIN-dez-MO-seez) are joints at which two bones are bound by a ligament only. (Ligaments also bind bones together at synovial joints, but are not the exclusive means of holding those joints together.) Syndesmoses are the most movable of the fibrous joints. The radius and ulna are bound to each other side by side, as are the tibia and fibula, by a syndesmosis in which the ligament forms a broad sheet called an interosseous membrane along the shafts of the two bones (see fig. 9.3c).

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
