Enarthrosis

Enarthrosis is a type of joint in the human body that allows for a wide range of movement. This type of joint, also known as a ball-and-socket joint, is one of the most flexible and mobile joints in the body. The hip joint and the shoulder joint are examples of enarthrosis.

Structure

The structure of an enarthrosis joint is characterized by a ball-like structure (the head of the bone) fitting into a cup-like structure (the socket). This allows for movement in multiple directions. The bone that makes up the ball part of the joint is rounded at the end and fits into the socket, which is a depression in another bone. This structure allows for a wide range of movement, including rotation.

Function

The main function of an enarthrosis joint is to allow for a wide range of movement. This includes flexion (bending), extension (straightening), abduction (moving away from the midline of the body), adduction (moving towards the midline of the body), and rotation. The design of the joint allows for this wide range of movement while also providing stability.

Examples

The most common examples of enarthrosis joints in the human body are the hip joint and the shoulder joint. These joints allow for a wide range of movement and are crucial for many daily activities.
