Multiple choice biology body movement joints in the human body our skeletal system and the skin joints

Ginglymoid/hinge joint occurs in

  1. Elbow and shoulder

  2. Elbow and knee

  3. Atlas and odontoid process

  4. Knee and ankle
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Joints are points of contact between bones, or between bones and cartilages.
  • Synovial joints are characterized by the presence of a fluid-filled synovial cavity between the articulating surfaces of the two bones. These joints help in locomotion and many other movements. 
  • A hinge joint (ginglymus) is a joint in which the articular surfaces are molded to each other in such a manner as to permit motion only in one plane.
  • The knee joint and elbow is a hinge joint/ ginglymoid i.e a type of synovial joint. 
  • So, the correct answer is 'Elbow and Knee'.

B Correct answer
Explanation

A synovial joint is a connection between two bones which consists of a cartilage lined cavity filled with fluid. The knee joint is the biggest synovial joint in the human body. At the junction of the knee, the large femur bone of the thigh connects to both the tibia and fibula of the leg, as well as to the patella or knee cap. So, the correct answer is 'Knee joint'.

C Correct answer
Explanation
  • Joints are points of contact between bones, or between bones and cartilages.
  • Synovial joints are characterized by the presence of a fluid-filled synovial cavity between the articulating surfaces of the two bones. These joints help in locomotion and many other movements.
  • Synovial joints are freely movable joint. Hence synovial fluid is present in freely movable joint.
  • So,the correct answer is 'Freely movable joints'.

Friction is lessened in ball-and-socket joint by

  1. Coelomic fluid

  2. Synovial fluid

  3. Pericardial fluid

  4. Mucin
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Synovial fluid is the pale yellow fluid that is present in every joint of the human body. It helps the bone able to slide past each other without causing damage to the ends of the bone. It means that synovial fluid lessens the friction in ball and socket joint. So, the correct answer is 'Synovial fluid'.
