1.1.4 Movement at synovial joints

• What are synovial joints known for in the body?

  High mobility
• Articular cartilage in synovial joints reduces friction and absorbs shocks.


  True
• Match the type of synovial joint with its example:

  Ball and Socket ↔️ Shoulder

  Hinge ↔️ Knee

  Pivot ↔️ Radioulnar joint
• Synovial fluid lubricates the joint and nourishes articular cartilage.


  True
• The saddle joint, found in the thumb, allows for multiaxial movement with a cup-like fit
• What is the function of synovial fluid in a synovial joint?

  Reduce friction and nourish cartilage
• What movement type involves decreasing the angle between two bones?

  Flexion
• Which movement type moves a limb away from the body's midline?

  Abduction
• What is flexion at a synovial joint?

  Decreasing the joint angle
• Flexion involves decreasing the angle between two bones.
• Adduction is the movement of a limb towards the midline of the body.


  True
• What is circumduction at a synovial joint?

  Circular movement combining flexion, extension, abduction, and adduction
• The specific type of movement at a synovial joint depends on its structure and design.
• What is the function of articular cartilage in synovial joints?

  Reduces friction and absorbs shocks
• What is the role of ligaments in synovial joints?

  Connect bones and provide stability
• Which type of synovial joint allows movement along one plane?

  Hinge
• A saddle joint facilitates multiaxial movement with a cup-like fit.
• How does articular cartilage reduce friction in synovial joints?

  Provides a smooth, low-friction surface
• Ligaments provide stability to synovial joints by limiting the range of motion.


  True
• What is the movement type called when the angle between two bones decreases, bringing them closer together?

  Flexion
• Abduction is the movement of a limb or body part away from the midline
• Key components of synovial joints include articular cartilage, synovial fluid, and ligaments
• What are the primary types of synovial joints categorized by?

  Shape and range of motion
• Arrange the movement types in order from least to most range of motion:

  1️⃣ Hinge

  2️⃣ Gliding

  3️⃣ Pivot

  4️⃣ Ball and Socket
• Which type of synovial joint allows for rotation around a single axis?

  Pivot
• Gliding joints, such as those in the vertebral column, allow for sliding movements.


  True
• Ligaments in synovial joints provide stability and limit the range of motion
• Extension increases the angle between two bones.

  True
• Moving a limb towards the midline of the body is called adduction
• Extension at a synovial joint increases the angle between two bones.

  True
• What is abduction at a synovial joint?

  Moving a limb away from the midline
• Rotation at a synovial joint involves turning a bone around its longitudinal axis.
• Gliding movements at synovial joints involve sliding between relatively flat joint surfaces.


  True
• Synovial joints are the most common type of joint in the body and are known for their high mobility.


  True
• Synovial fluid lubricates and nourishes the joint.
• A ball and socket joint allows motion in all directions.
• The pivot joint allows rotation around a single axis.

  True
• Gliding joints are found in the vertebral joints and allow sliding movements.

  True
• Synovial fluid reduces friction and nourishes articular cartilage.
• Order the following types of movement at synovial joints based on their complexity:

  1️⃣ Flexion

  2️⃣ Extension

  3️⃣ Rotation

  4️⃣ Circumduction
