Types of saddle joints

Compared to ball and socket joints saddle joints do not provide a complete rotation. Compared to ball and socket joints saddle joints do not provide a complete rotation.

Consists of a bone with a ball-shaped head that attaches with the cup- shaped cavity of another bone.

Types of saddle joints. Saddle joints have two basic types of movement known as flexion-extension and abduction-adduction. Flexion and extension are opposite movements but theyre easy to visualize. Saddle Joints - Saddle joint is the biaxial joint that allows the movement on two planesflexionextension and abductionadduction.

For example the thumb is the only bone within the physical body having a saddle joint. Ball-and-Socket Joints- Here one bone is hooked into the cavity of another bone. This type of joint helps in rotatory movement.

Compared to ball and socket joints saddle joints do not provide a complete rotation. Flexibility and the interlocking is more in saddle joints when compared to other types of synovial joints. The structure of saddle joints is a combination of both hinge joint and ball and socket joint.

The types of movement a saddle joint allows are flexion extension adduction and abduction. All types of gripping motion are provided by saddle joint such as using a pen grasping your mobile phone and steering the wheel of your car. Examples of saddle joints are the thumb joint.

Through it you can move the thumb in different directions up down back and forth. In fact the thumb is the only finger than can move freely. Specifically the saddle joint structure is at the base of the thumb carpal and metacarpal.

The trapezium of the wrist is also categorized as saddle joint. Saddle joints allow movement with two degrees of freedom much like condyloid joints. They allow flexion extension abduction adduction and therefore also allow circumduction.

Unlike ball and socket joints saddle joints do not allow axial rotation. Lets have a glance at the various types of joints in the human body and discover how it helps us to move. Joints Classification Fibrous Joints Cartilaginous Joints Synovial Joints Ball and Socket Joints Pivotal Joints Hinge Joints Saddle Joints Condyloid Joints Gliding Joints.

Locomotion is the ability to move from one place to another. Synovial joints are further classified into six different categories on the basis of the shape and structure of the joint. The shape of the joint affects the type of movement permitted by the joint Figure 1.

These joints can be described as planar hinge pivot condyloid saddle or ball-and-socket joints. The bones at these joints form what looks like a rider on a saddle. One bone is turned inward at one end while the other is turned outward.

An example of a saddle joint is the thumb joint between the thumb and palm. Bones at this type. There are six types of synovial joints.

Ball-and-Socket Joint Condyloid Joint Gliding Joint Hinge Joint Pivot Joint Saddle Joint. Ball-and-Socket Joint Ball-and-Socket Joint. Consists of a bone with a ball-shaped head that attaches with the cup- shaped cavity of another bone.

What are the Best Examples of Saddle Joint. Following are some of the few examples of saddle joint in the human body. Carpometacarpal joint The best-known example of the saddle joint is the carpometacarpal joint of the thumb formed by trapezium bone sitting on the first metacarpal.

This carpometacarpal joint of the human thumb makes it opposable and allows it to span across the palm. The different types of synovial joints are the ball-and-socket joint shoulder joint hinge joint knee pivot joint atlantoaxial joint between C1 and C2 vertebrae of the neck condyloid joint radiocarpal joint of the wrist saddle joint first carpometacarpal joint between the trapezium carpal bone and the first metacarpal bone at the base of the thumb and plane joint facet joints of vertebral column between. A saddle joint is an articulation between two bones that are saddle-shaped or concave in one direction and convex in another.

This type of joint is biaxial and one example is the first carpometacarpal joint between the trapezium carpal and the first metacarpal bone of the thumb. Synovial joints are by far the most common classification of a joint within the human body. They are highly moveable and all have a synovial capsule collagenous structure surrounding the entire joint a synovial membrane the inner layer of the capsule which secretes synovial fluid a lubricating liquid and cartilage known as hyaline cartilage which.

There are three types of joints. Fibrous joint - In this joint the bones are connected to each other by dense fibrous connective tissue usually collagen. There is no joint cavity.

The joint does not allow any movement so they are also called fixed or immovable joints. Saddle joints indicated by letter C in our illustration are similar to hinge joints but provide more range of motion. In the case of a saddle joint the bone sitting on the saddle can move in an oval shape relative to the other bone.

Our thumb is a classic example of a saddle joint in action. Joints are formed where bones come together. The six types of synovial joints are the pivot hinge saddle plane condyloid and ball-and-socket joints.

Pivot joints are found in your neck. The different types of synovial joints are the ball-and-socket joint shoulder joint hinge joint knee pivot joint atlantoaxial joint between C1 and C2 vertebrae of the neck condyloid joint radiocarpal joint of the wrist saddle joint first carpometacarpal joint. The third type of synovial joint is the condyloid joint.

In Greek condyloid means knuckle-like. This type of joint allows movement in two axes. Therefore you can bend it straighten it move it from side to side and rotate it.

An example is your wrist joint. The fourth synovial joint type is the saddle joint.
