Articulations and whatnot

What anatomical movements occur at the hip joint when someone properly does jumping jacks? Choose all that apply.

• abduction
• adduction
• extension
• flexion
• lateral rotation

Which of the following are classifications of joints based on function?

• Synarthroses
• Diarthroses
• Amphiarthroses
• Fibrous joints
• Synovial joints

Which of the following are capable of abduction and adduction?

• glenohumeral joint
• joint between the radius and carpals
• hip joint
• elbow joint
• knee joint

What classifications of joints can be described as immovable joints? Choose all that apply.

• fibrous
• synarthroses
• cartilaginous
• synovial
• amphiarthroses

Which type of synovial joint has the most mobility?

• Condyloid
• Hinge
• Saddle
• Ball and socket

What is the function of the synovial fluid in synovial joints?

• To reduce friction between the bones and nourish the articular cartilage
• To hold the bones together and provide stability
• To cover the articulating surfaces of the bones
• To secrete synovial membrane

Which of the following is NOT a characteristic of synovial joints?

• They allow for free movement and greater mobility
• They have a joint cavity filled with synovial fluid
• They are found in the limbs, such as the shoulder and hip joints
• They have a fibrous connective tissue structure

Based on the information in the text, why are synovial joints more prone to injury compared to other types of joints?

• Synovial joints have a weaker structure.
• Synovial joints have a higher risk of dislocation.
• Synovial joints experience more wear and tear.
• Synovial joints lack proper lubrication.

What is the purpose of the articular capsule in synovial joints?

• To reduce friction between the bones.
• To hold the bones together and provide stability.
• To secrete synovial fluid.
• To cover the articulating surfaces of the bones.

What inference can be made about the relationship between synovial joints and mobility?

• Synovial joints restrict movement due to their unique structure.
• Synovial joints allow for limited movement compared to other joint types.
• Synovial joints are designed to maximize joint mobility.
• Synovial joints are only found in immobile parts of the body.
