Types of synovial joints

The tutorial covers the basics of joints, focusing on synovial joints, their structure, types, and movement axes. It explains the components of synovial joints using the knee as an example and describes the six types of synovial joints: plane, pivot, hinge, ellipsoid, saddle, and ball and socket. The tutorial also discusses joint issues like osteoarthritis and concludes with a review of the key points.

What is the primary characteristic of fibrous joints?

• They are tightly linked by fibrous tissue.

• They allow a large range of motion.

• They are filled with synovial fluid.

• They are the most common type of joint.

Which component of a synovial joint provides a smooth surface for articulation?

• Articular cartilage

• Reinforcing ligaments

• Synovial membrane

• Articular capsule

What is the role of synovial fluid in synovial joints?

• To absorb shock

• To provide nutrients to the joint

• To connect bones together

• To lubricate the articular surfaces

What is the primary function of articular disks in synovial joints?

• To increase joint flexibility

• To absorb compression forces

• To secrete synovial fluid

• To connect muscles to bones

How are uniaxial joints classified?

• They move around two axes.

• They move around three or more axes.

• They do not allow any movement.

• They move around one axis only.

Which type of synovial joint allows for gliding movements?

• Plane joint

• Pivot joint

• Ball and socket joint

• Hinge joint

What movement is allowed by pivot joints?

• Gliding movements

• Multiaxial movement

• Flexion and extension

• Rotation around a central axis

Which joint type is characterized by a ball-shaped head fitting into a socket?

• Ball and socket joint

• Ellipsoid joint

• Saddle joint

• Hinge joint

Which joint is an example of a modified hinge joint?

• Elbow

• Shoulder

• Knee

• Ankle

What is a common symptom of osteoarthritis?

• Increased joint flexibility

• Joint pain and stiffness

• Enhanced joint lubrication

• Rapid joint healing
