1.1.3 Types of synovial joints

• The atlantoaxial joint in the neck allows for rotational movements around a central axis.


  True
• The joint cavity of a synovial joint is filled with synovial fluid
• What is the primary function of synovial fluid in a synovial joint?

  Lubrication
• Ligaments in synovial joints stabilize the joint and prevent excessive movement.


  True
• Which type of synovial joint allows for circular and rotational movements?

  Ball-and-Socket
• Pivot joints allow for rotation around a central axis.

  True
• Ellipsoidal joints allow for flexion, extension, abduction, and adduction
• Ball-and-socket joints allow for circular, rotational, and multi-directional movements.


  True
• Hinge joints can perform flexion and extension movements, such as in the elbow and knee joints.


  True
• The atlantoaxial joint in the neck is an example of a pivot joint.


  True
• The intercarpal joints in the wrist are examples of gliding joints.


  True
• Match the joint type with its example:

  Ball-and-Socket ↔️ Shoulder joint, hip joint

  Hinge ↔️ Elbow joint, knee joint

  Pivot ↔️ Atlantoaxial joint in the neck
• What type of joint is the most common and movable in the human body?

  Synovial joint
• Synovial joints reduce friction and provide nutrients through synovial fluid.

  True
• Articular cartilage in synovial joints protects bones from wear
• Match the synovial joint type with its range of motion:

  Ball-and-Socket ↔️ Wide range of circular and rotational movements

  Hinge ↔️ Flexion and extension in one plane

  Pivot ↔️ Rotation around a central axis
• Hinge joints allow for flexion and extension
• What type of synovial joint features flat or slightly curved bone surfaces sliding against each other?

  Gliding
• The rounded head of one bone in a ball-and-socket joint fits into a cup-shaped cavity
• Hinge joints allow for movement in only one plane
• Pivot joints allow for rotation around a central axis
• Gliding joints have flat or slightly curved bone surfaces
• Ellipsoidal joints have an oval-shaped end of one bone that fits into a slightly oval cavity
• Ellipsoidal joints allow for flexion, extension, abduction, and adduction movements.


  True
• Ball-and-socket joints allow for a wide range of circular and rotational
• Match the joint type with its real-life example:

  Gliding ↔️ Intercarpal joints in the wrist

  Ellipsoidal ↔️ Radiocarpal joint in the wrist
