Types of Joints Quiz

Synarthrotic Joints: Immovable joints, e.g., sutures in the skull; connected by fibrous tissue or hyaline cartilage in synchondroses.
Amphiarthrotic Joints: Slightly movable, exemplified by the manubriosternal joint and the pubic symphysis; characterized by cartilaginous connections.
Diarthrotic Joints: Freely movable joints, primarily synovial joints that provide a wide range of motion.

Ball and Socket Joint: A type of synovial joint with a rounded bone fitting into a cup-like cavity, allowing multi-directional movement.
Ellipsoidal/Condyloid Joint: A synovial joint allowing flexion, extension, adduction, abduction, and circumduction without axial rotation.
Hinge Joint: Allows motion in one plane, exemplified by the elbow, where a convex bone part fits into a concave counterpart.
Gliding Joint: Freely moving joints that allow gliding motions between flat or slightly curved bone surfaces.
Pivot Joint: Allows rotation around a single axis, like the joint between the radius and ulna, accommodating rotational movements.

Facet Joint: Found in the spine, these joints enhance flexibility and allow bending and twisting; nerves exit the spinal cord through these joints.

Glenohumeral Joint: Composed of the clavicle, scapula, and humerus, enabling shoulder movement.
Coxal Joint: A ball-and-socket joint formed by the femur and the ilium, ischium, and pubis bones of the pelvis.
Patellofemoral Joint: Formed by the femur and patella, part of the knee structure situated between the femur and tibia.

Pelvis Composition: Formed by the sacrum, coccyx, and two hip bones (ilium, ischium, pubis); vital for bipedal locomotion and organ protection.

Tibia and Fibula: The medial malleolus is the projection on the ankle's inner side, formed by the tibia; the fibula runs laterally.

Types of Synovial Joints: Include pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints, determined by structural design affecting functionality.

Muscle Functionality: Muscles cross joints to facilitate movement; without crossing a joint, muscles cannot enable motion.
Tendons: Connect muscles to bones, crucial for movement and body functions such as digestion, respiration, and locomotion.
