#1
Which type of joint allows the widest range of movement?
Ball and socket joint
ExplanationBall and socket joints provide a wide range of movement due to the spherical head of one bone fitting into the cup-like socket of another.
#2
In the human body, which joint connects the forearm bones (radius and ulna) to the upper arm bone (humerus)?
Elbow joint
ExplanationThe elbow joint connects the forearm bones, allowing for flexion and extension movements.
#3
What is the medical term for inflammation of a joint, often causing pain and stiffness?
Arthritis
ExplanationArthritis refers to the inflammation of joints, resulting in pain, swelling, and reduced mobility.
#4
Which of the following is not a component of a synovial joint?
Sutures
ExplanationSutures are fibrous joints, not present in synovial joints, which include components like synovial membrane, articular cartilage, and synovial fluid.
#5
Which type of joint is found between the first two cervical vertebrae, allowing nodding of the head?
Pivot joint
ExplanationPivot joints, as seen between the first two cervical vertebrae, enable nodding movements of the head.
#6
What type of joint is found between the vertebrae in the spine?
Cartilaginous joint
ExplanationCartilaginous joints between vertebrae provide flexibility and absorb shock in the spine.
#7
Which ligament connects the thigh bone (femur) to the shin bone (tibia) in the knee joint?
Anterior cruciate ligament
ExplanationThe anterior cruciate ligament stabilizes the knee joint and connects the femur to the tibia.
#8
What is the term for the movement that decreases the angle between two bones, such as bending the elbow?
Flexion
ExplanationFlexion is the movement that decreases the angle between two bones, commonly observed in actions like bending the elbow.
#9
Which joint allows rotational movement, such as turning the head or twisting the forearm?
Pivot joint
ExplanationPivot joints enable rotational movements, like turning the head or twisting the forearm around a central axis.
#10
Which type of joint is commonly found between the carpal bones in the wrist?
Synovial joint
ExplanationSynovial joints, with a synovial cavity, are common between carpal bones, allowing flexible movements in the wrist.
#11
In which joint is the hyaline cartilage found, providing smooth movement between bones?
Synovial joint
ExplanationSynovial joints, containing hyaline cartilage, facilitate smooth movement between bones with a synovial fluid-filled cavity.
#12
What is the function of synovial fluid in a synovial joint?
To allow smooth movement
ExplanationSynovial fluid lubricates and cushions joints, facilitating smooth movement and reducing friction between articulating bones.
#13
Which of the following is an example of a fibrous joint in the human body?
Sutures of the skull
ExplanationSutures, immovable fibrous joints, connect the bones of the skull, providing stability and protection.
#14
What is the purpose of bursae in the human body?
To provide cushioning between bones and tendons
ExplanationBursae act as fluid-filled sacs, cushioning and reducing friction between bones, tendons, and muscles.
#15
Which ligament connects the two hip bones (coxal bones) in the pelvic girdle?
Iliofemoral ligament
ExplanationThe iliofemoral ligament connects the hip bones and contributes to the stability of the hip joint.
