Quiz Questions chapter 9

Which type of joint confers the greatest range of motion?

-ball and socket joint -hinge joint -planar joint -saddle joint

An injury to a joint that alters the articular surfaces of the bones of the joint may affect the range of motion of that joint. Which factor that influences range of motion is the most likely one that has been negatively affected in this situation?

-contact of soft parts -strength and tension of the joint ligaments -arrangement and tension of the muscles -structure of shape of the articulating bones

Which of the following could contribute to a decreased range of motion if a person wore a cast for several weeks which prohibited movement at a particular joint, such as the elbow? (Choose all that apply)

-decrease in synovial fluid reducing lubrication -muscle atrophy resulting in weakness in muscles that stabilize and move the joint -decrease in bone density -reduced flexibility of tendons and ligaments

Which of the following is an example of a fibrous joint?

-epiphyseal plate -interosseus membrane -the pubic symphysis -the joint between the manubrium and body of the sternum

Chuck is at a pizza parlor and ordering sodas for his group of friends. He holds up a hand and spreads his fingers wide apart to indicate he wants five large sodas? What type of movement of his fingers was this?

-flexion -extension -adduction -abduction

Which of the following is NOT a hinge joint?

-knee -shoulder -interphalangeal joints -elbow

A ballerina who points her toes to stand literally on the tip of her toes for a dance movement is doing what type of special movement at the ankle joint?

-plantar flexion -pronation -eversion -dorsiflexion

A body builder is doing bicep curls, bending their arm and bringing the weight closer to the shoulder. What type of movement is this?

-rotation -flexion -abduction -extension

Which of the following is not a function of synovial fluid?

-shock absorption -to maintain a sterile environment within the joint cavity -to provide lubrication in the joint and reduce friction between articular surfaces -to act as a medium for the diffusion of oxygen and nutrients

The bodies of adjacent vertebrae are conncected by pads of fibrocartilage. The articulations between adjacent vertebrae are called _____.

-synchondroses -symphyses -syndesmoses -synovial joints

Most of the freely movable joints of the body could be classified both structurally and functionally as _______ .

-synovial and amphiarthrosis -fibrous and diarthrosis -synovial and diarthrosis -cartilaginous and synarthroses

An immovable joint, the sagittal suture, which joins the two parietal bones of the skull is classified as a ______.

-synovial joint -amphiarthrosis -diarthrosis -synarthrosis

Which of the following is an example of a uniaxial joint?

-the ball and socket joint between the scapula and humerus -the hinge joint of the elbow -the saddle joint between the thumb and trapezium of the wrist -the plane joints between carpal bones

The wider pelvis of females and the greater angle this creates between the femur and the tibia puts females at a greater risk than males for damage to which structure of the knee?

-the patellar ligament -the posterior cruciate ligament -articular capsule -the anterior cruciate ligament

When walking down stairs or a steep hill, the knee is flexed. Which structure prevents the tibia from sliding too far posteriorly, and the femur from sliding too far anteriorly?

-the pateller ligament -the posterior cruciate ligament -medial meniscus -the anterior cruciate ligament

This joint is a complex and weight-bearing joint, and is the most frequently injured joint in the body. The articular surfaces of the bones do not have complementary surfaces, so the stability of the joint depends mostly on its ligaments and the muscles that move the joint.

-the sacroiliac joint -the knee joint -the hip joint -the shoulder joint
