Understanding Joint Structures and Functions

Which of the following combinations correctly describes the structural and functional classifications of sutures in the skull?

• Fibrous and synarthrotic

• Cartilaginous and amphiarthrotic

• Synovial and diarthrotic

• Fibrous and diarthrotic

In the knee joint, which structure prevents forward sliding of the tibia and hyperextension of the knee?

• Posterior cruciate ligament

• Medial collateral ligament

• Anterior cruciate ligament

• Lateral meniscus

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

• Presence of a joint cavity

• Articular cartilage covering bone ends

• Synovial membrane producing synovial fluid

• Direct bone-to-bone contact

The shoulder joint's stability is primarily maintained by:

• The depth of the glenoid cavity

• Strong ligaments surrounding the joint

• The rotator cuff muscles

• The acromion process

Which type of joint is characterized by a fibrocartilaginous pad that connects the bones?

• Synovial joint

• Fibrous joint

• Cartilaginous joint

• Hinge joint

What is the primary function of the menisci in the knee joint?

• To produce synovial fluid

• To absorb shock and improve joint stability

• To connect muscles to bones

• To prevent hyperextension

Which of the following joints is an example of a pivot joint?

• Elbow joint

• Hip joint

• Atlantoaxial joint

• Knee joint

Which of the following is a characteristic feature of a ball-and-socket joint?

• Allows only flexion and extension

• Allows movement in multiple planes

• Has a flat articular surface

• Is a type of fibrous joint

Which structure in the knee joint is most commonly injured in athletes?

• Medial meniscus

• Anterior cruciate ligament

• Lateral collateral ligament

• Patellar tendon

Regarding the elbow joint complex, which of the following statements is correct?

• The ulnar collateral ligament primarily prevents hyperextension of the elbow

• The anular ligament surrounds the head of the ulna and allows for pronation and supination

• The humeroulnar articulation is classified as a pivot joint, allowing for flexion and extension

• The joint between the head of the radius and the capitulum of the humerus is a plane joint that contributes to pronation and supination
