#1
What type of movement occurs at the elbow joint during flexion and extension?
Angular movement
ExplanationBending (flexion) and straightening (extension) of the joint.
#2
What type of joint is the sutures between skull bones?
Fibrous joint
ExplanationImmovable joint consisting of dense fibrous connective tissue.
#3
What is the term for a joint movement that decreases the angle between two bones?
Flexion
ExplanationBrings two bones closer together, decreasing the angle between them.
#4
What is the term for a joint movement that increases the angle between two bones?
Extension
ExplanationStraightening or increasing the angle between two bones.
#5
In which type of joint is the articular surface covered with hyaline cartilage?
Synovial joint
ExplanationAllows smooth movement due to the presence of hyaline cartilage covering the articulating surfaces.
#6
Which type of joint allows the greatest range of motion?
Ball-and-socket joint
ExplanationAllows movement in multiple directions due to its spherical head fitting into a socket.
#7
During dorsiflexion and plantarflexion, which joint is primarily involved?
Ankle joint
ExplanationMovement of the foot upwards (dorsiflexion) and downwards (plantarflexion) around the ankle.
#8
Which of the following joints allows only gliding movements?
Gliding joint
ExplanationAllows bones to glide past one another in various directions.
#9
Which movement is characterized by a circular motion around an axis?
Rotation
ExplanationTurning of a bone along its own axis.
#10
Which ligament is commonly injured in a lateral ankle sprain?
Anterior talofibular ligament (ATFL)
ExplanationOften overstretched or torn during excessive inversion of the ankle.
#11
Which joint allows opposition and reposition movements, as seen in thumb and little finger?
Carpometacarpal joint
ExplanationEnables the thumb to move across the palm and touch the fingertips.
#12
Which ligament stabilizes the knee joint on the medial side?
Medial collateral ligament (MCL)
ExplanationProvides stability and prevents excessive inward movement of the knee.
#13
What is the function of synovial fluid in a synovial joint?
Reduces friction between joint surfaces
ExplanationLubricates and nourishes the joint while reducing friction during movement.
#14
In which joint does pronation and supination occur?
Radioulnar joint
ExplanationRotational movements of the forearm around its longitudinal axis.
#15
What is the primary function of the meniscus in the knee joint?
To absorb shock and distribute load
ExplanationActs as a cushion and spreads the force of weight-bearing.
#16
Which ligament is commonly associated with stabilizing the shoulder joint?
Coracohumeral ligament
ExplanationStrengthens the upper part of the joint capsule and helps support the shoulder.
#17
Which joint allows for movements like protraction and retraction of the scapula?
Scapulothoracic joint
ExplanationMovement of the scapula away from (protraction) and towards (retraction) the spine.
