Human Joints Models | Human Anatomy Models

A joint is the union of two or more bones. The primary function of a joint is to allow movement. The movement of a joint is created by muscle contraction and the force pulling on the bones. Ligaments and joint capsules function to limit excessive or undesirable movement at a joint. Therefore, joints allow movement, muscles create the force to produce the movement, and ligaments and joint capsules limit movement or displacement at the joint. Joints also work to bear weight, absorb shock, and provide stability.

Joints are classified according to their structure and/or function. There are three main categories of joints. The functional categories are Synarthrodial (immoveable), Amphiarthrodial (slightly moveable), and Synarthrodial (freely moveable).

The six (6) types of Synarthrodial or freely moveable joints are:
