- Hinge, e.g. interphalangeal joints - fingers and toes.
- Ball and socket, e.g. hip and shoulder joints.
- Pivot, e.g. atlantoaxial joint between the atlas and axis - neck.
- Gliding (= "Condyloid" joint), e.g. between radius, scaphoid and lunate bones - wrist.
What are the joints in your body?
The most common synovial joints are listed below:
- Ball and socket joints, like your hip and shoulder joints, are the most mobile type of joint in the human body.
- Ellipsoidal joints, such as the joint at the base of your index finger, allow bending and extending, rocking from side to side, but rotation is limited.

What is an example of a fixed joint?
The main function of the joints is to allow both movement and flexibility. Fixed joints permit stability to certain areas of the body, although they do not move. Examples of fixed joints include the joints between the bones in the skull and the joint where the radius and ulna bones meet in the lower arm.
4
What is the other name for fixed joints?
Most fibrous joints are also called "fixed" or "immovable", because they do not move. These joints have no joint cavity and are connected via fibrous connective tissue. The skull bones are connected by fibrous joints called sutures.In fetal skulls the sutures are wide to allow slight movement during birth.

What is the function of the joints?
Functions of Joints. Joints connect bones within your body, bear weight and enable you to move. They are made up of bone, muscles, synovial fluid, cartilage and ligaments. Different joints provide unique points of stability and mobility.
6
What are the 6 types of joints in the body?
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 vertebrae, while hinge joints are located in your elbows, fingers, and knees. Saddle and plane joints are found in your hands.

What are the three main types of joints?
A joint is the point where two or more bones meet. There are three main types of joints; Fibrous (immovable), Cartilaginous (partially moveable) and the Synovial (freely moveable) joint.

What is the difference between a tendon and a ligament?
Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
10
What are the joints?
Joints, also known as articulations, are strong connections that join the bones, teeth, and cartilage of the body to one another. Each joint is specialized in its shape and structural components to control the range of motion between the parts that it connects.
11
What type of joint is in the fingers?
Interphalangeal joints: These hinge joints allow flexion and extension. They join the heads of the phalanges with the bases of the next distal phalanges. Each finger (digits two through five) has one proximal interphalangeal joint and one distal interphalangeal joint. The thumb has only one interphalangeal joint.
12
Which muscle bends the joint?
The extensor muscle relaxes and stretches as the flexor muscle contracts to bend the joint. The flexor relaxes and the extensor contracts to straighten (or extend) the limb at the same joint. Muscles get their signals to contract and relax from the brain. Ligaments are long, fibrous straps that fasten bones together.
13
What is a fixed joint?
Fixed joints. Some of your joints, like those in your skull, are fixed and don't allow any movement. The bones in your skull are held together with fibrous connective tissue. Slightly movable joints.
14
What is a Condyloid joint?
A condyloid joint (also called condylar, ellipsoidal, or bicondylar) is an ovoid articular surface, or condyle that is received into an elliptical cavity. This permits movement in two planes, allowing flexion, extension, adduction, abduction, and circumduction.
15
What type of joint is the knee?
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations
16
What is joint?
A joint or articulation (or articular surface) is the connection made between bones in the body which link the skeletal system into a functional whole. They are constructed to allow for different degrees and types of movement.
17
What are the joints in the skeletal system?
Types of Joints in the Skeletal System
- Fibrous Joint. The fibrous (fixed or immovable) joints in the skeletal system include the sutures of the skull.
- Ball-and-Socket Joint.
- Saddle Joint.
- Hinged Joint.
- Gliding Joint.
- Pivot Joint.
- Condyloid Joint.
19
What type of joint is slightly movable?
Slightly movable joints are called amphiarthroses. The singular form is amphiarthrosis. In this type of joint, the bones are connected by hyaline cartilage or fibrocartilage. The symphysis pubis is a slightly movable joint in which there is a fibrocartilage pad between the two bones.
