#1
Which type of joint allows the widest range of motion?
Ball-and-socket joint
ExplanationAllows movement in multiple directions with a wide range of motion.
#2
What type of tissue covers the ends of bones in synovial joints?
Cartilage
ExplanationProvides a smooth surface for movement and reduces friction.
#3
What type of movement occurs in a gliding joint?
Linear movement in any direction
ExplanationAllows bones to glide past each other in various directions.
#4
Which of the following joints is an example of a hinge joint?
Elbow joint
ExplanationPrimarily allows movement in one plane, flexion/extension.
#5
What is the purpose of the synovial membrane in a synovial joint?
To produce synovial fluid
ExplanationProduces synovial fluid, which lubricates and nourishes the joint.
#6
Which of the following joints allows for opposition movement?
Wrist joint
ExplanationEnables the thumb to touch the tips of other fingers.
#7
Which ligament prevents hyperextension of the knee joint?
Posterior cruciate ligament (PCL)
ExplanationStabilizes the knee joint and prevents backward movement beyond its normal range.
#8
What is the function of synovial fluid in synovial joints?
All of the above
ExplanationLubricates the joint, provides nutrients to cartilage, and removes waste products.
#9
What is the function of the meniscus in the knee joint?
All of the above
ExplanationProvides cushioning, shock absorption, and stability to the knee joint.
#10
Which of the following is NOT a structural classification of synovial joints?
Fibrous joint
ExplanationFibrous joints are characterized by the absence of a synovial cavity.
#11
What type of joint allows only rotational movement?
Pivot joint
ExplanationPermits rotation around a single axis.
#12
Which of the following is a function of articular cartilage?
All of the above
ExplanationReduces friction, absorbs shock, and provides a smooth surface for joint movement.
#13
Which of the following is an example of a condyloid joint?
Wrist joint
ExplanationAllows movement in two planes, flexion/extension, and abduction/adduction.
#14
What is the primary function of the synovial membrane in a synovial joint?
To produce synovial fluid
ExplanationProduces synovial fluid, which lubricates and nourishes the joint.
#15
Which ligament is most commonly injured in a shoulder dislocation?
Glenohumeral ligament
ExplanationProvides stability to the shoulder joint and is susceptible to injury during dislocation.
#16
What is the function of the bursae in synovial joints?
To reduce friction
ExplanationActs as cushions between bones, tendons, and muscles to reduce friction.
#17
Which ligament is commonly known as the 'collarbone'?
Acromioclavicular ligament
ExplanationConnects the acromion process of the scapula to the clavicle.
#18
Which of the following bones does not contribute to the knee joint?
Fibula
ExplanationThe fibula is not part of the knee joint but is adjacent to it.
