#1
Which type of joint allows movement in multiple directions?
Ball and socket joint
ExplanationAllows movement in multiple directions due to its spherical shape.
#2
Which of the following is NOT a type of synovial joint?
Suture joint
ExplanationSuture joints are fibrous joints, not synovial joints.
#3
Which of the following movements is NOT possible at the shoulder joint?
Extension
ExplanationExtension is not possible; shoulder allows flexion, abduction, adduction, and rotation.
#4
What is the purpose of the synovial fluid in a joint?
To reduce friction between the bones
ExplanationLubricates and reduces friction between joint surfaces.
#5
Which of the following is a function of the articular capsule?
To provide stability to the joint
ExplanationEncloses the joint, providing stability and containing synovial fluid.
#6
What is the function of articular cartilage in joints?
To prevent friction
ExplanationReduces friction between bones during movement.
#7
Which ligament is commonly injured in a sprained ankle?
Anterior talofibular ligament (ATFL)
ExplanationOften injured due to inversion sprains of the ankle.
#8
Which type of joint allows rotation around its axis?
Pivot joint
ExplanationAllows rotational movement around a single axis.
#9
Which structure helps to hold bones together at a synovial joint?
Ligament
ExplanationConnects bone to bone, providing stability.
#10
What is the function of the ACL (anterior cruciate ligament) in the knee joint?
To prevent hyperextension of the knee
ExplanationLimits hyperextension and controls rotational movements of the knee.
#11
What is the function of the meniscus in the knee joint?
To absorb shock
ExplanationActs as a shock absorber and distributes load in the knee joint.
#12
What is the function of the bursae in joints?
To cushion and reduce friction
ExplanationSacs filled with fluid that cushion and reduce friction between structures.
#13
Which ligament provides stability to the medial side of the knee joint?
Medial collateral ligament (MCL)
ExplanationStabilizes the inner aspect of the knee against valgus forces.
#14
What is the function of the rotator cuff muscles in the shoulder joint?
To provide stability and control movements
ExplanationStabilizes the shoulder and facilitates various movements.
#15
Which structure provides nutrition to the avascular articular cartilage?
Synovial fluid
ExplanationSupplies nutrients to the cartilage, aiding in its maintenance and repair.
