#1
Which joint is responsible for the up-and-down movement of the head, as in nodding?
Atlanto-occipital joint
ExplanationFacilitates the nodding movement of the head between the atlas and the occipital bone.
#2
Which joint is responsible for the flexion and extension of the forearm?
Elbow joint
ExplanationFacilitates bending (flexion) and straightening (extension) of the forearm.
#3
Which joint is responsible for the movement of the jaw during chewing?
Temporomandibular joint
ExplanationEnables movements like chewing, speaking, and yawning.
#4
What type of joint is the ankle joint?
Hinge joint
ExplanationAllows movement primarily in one direction, like bending and straightening.
#5
In the context of joints, what does the term 'ROM' stand for?
Range of Movement
ExplanationRefers to the extent of movement that a joint is capable of.
#6
Which type of joint allows for the greatest range of motion?
Ball and socket joint
ExplanationAllows movement in multiple directions due to its spherical structure.
#7
What is the function of synovial fluid in joints?
Reduce friction
ExplanationLubricates the joint to minimize friction during movement.
#8
What is the role of ligaments in a joint?
Connect bones to bones
ExplanationProvide stability by connecting bones to bones.
#9
What is the main function of the cartilage in a joint?
Reduce friction and absorb shock
ExplanationProvides cushioning, reduces friction, and absorbs shock during movement.
#10
Which joint allows for rotational movement, such as turning the head?
Pivot joint
ExplanationEnables rotation around its axis, allowing rotational movements like turning the head.
#11
What is the role of tendons in the context of joints?
Connect muscles to bones
ExplanationAttach muscles to bones, facilitating movement.
#12
In which joint would you find a meniscus?
Knee joint
ExplanationActs as a shock absorber and enhances stability in the knee joint.
#13
What is the primary function of the synarthrosis joint?
Provide stability and little to no movement
ExplanationMainly provides stability with minimal or no movement.
#14
What is the primary function of bursae in the joints?
Reduce friction between structures
ExplanationFluid-filled sacs that reduce friction between tendons, ligaments, and bones.
#15
Which joint is commonly affected by osteoarthritis?
Knee joint
ExplanationDegeneration of cartilage in the knee joint, leading to pain and stiffness.
#16
Which ligament is commonly injured in the knee joint?
Anterior cruciate ligament
ExplanationFrequently injured during activities involving sudden stops or changes in direction.
#17
What is the function of the meniscus in the knee joint?
Reduce friction and absorb shock
ExplanationActs as a shock absorber, distributes load, and reduces friction in the knee joint.
