What is a joint that permits limited movement called?

A joint that permits limited movement is referred to as a slightly movable joint. This type of joint, also known as an amphiarthrosis, allows for a small degree of flexibility, enabling certain movements while still maintaining stability and structural integrity.

Examples of slightly movable joints include the joints between vertebrae in the spine, where the intervertebral discs provide cushioning and allow for slight movements such as bending and twisting. This limited movement is crucial for maintaining balance and posture, while still providing enough rigidity for support.

In contrast, immovable joints (synarthroses) completely restrict movement, ball-and-socket joints allow for a wide range of motion in multiple directions, and hinge joints permit movement in one direction similar to the motion of a door. Understanding the characteristics and functions of different joint types helps clarify the role that slightly movable joints play in the overall flexibility and movement of the skeletal system.
