#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
What is the primary movement involved in turning the sole of the foot medially?
Inversion
ExplanationMovement of the sole of the foot inward, towards the midline of the body.
#13
Which type of joint is found between adjacent vertebrae in the spine?
Cartilaginous joint
ExplanationAllows slight movement and provides support and flexibility to the spine.
#14
Which joint is responsible for the movement of nodding your head up and down?
Atlantooccipital joint
ExplanationAllows the head to nod forwards and backwards.
#15
Which joint is commonly affected by osteoarthritis in the human body?
Knee joint
ExplanationDegeneration of cartilage in the knee joint leads to osteoarthritis.
#16
What is the term for the movement that brings a body part closer to the midline of the body?
Adduction
ExplanationMovement towards the midline of the body.
#17
Which ligament stabilizes the knee joint on the medial side?
Medial collateral ligament (MCL)
ExplanationProvides stability and prevents excessive inward movement of the knee.
#18
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.
#19
In which joint does pronation and supination occur?
Radioulnar joint
ExplanationRotational movements of the forearm around its longitudinal axis.
#20
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.
#21
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.
#22
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.
#23
What is the primary function of the ACL (Anterior Cruciate Ligament) in the knee joint?
Resisting anterior tibial displacement
ExplanationPrevents the tibia from moving too far forward relative to the femur.
#24
Which joint allows the movement of the forearm to turn the palm downward?
Proximal radioulnar joint
ExplanationRotation of the forearm where the palm faces downward.
#25
What is the primary function of the bursae found in and around joints?
Reducing friction between structures
ExplanationSmall fluid-filled sacs that cushion and reduce friction between bones, tendons, and muscles.
