The joint of writs is of?

evs bones joints in the human body our skeletal system and the skin joints

  1. Hinge type

  2. Ball and socket type

  3. Gliding type

  4. Pivot type

Show answer
Correct Option: A

Ginglymoid/hinge joint occurs in

  1. Elbow and shoulder

  2. Elbow and knee

  3. Atlas and odontoid process

  4. Knee and ankle

Show answer
Correct Option: B
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'.

Largest synovial joint is

  1. Hip joint

  2. Knee joint

  3. Shoulder joint

  4. Ankle joint

Show answer
Correct Option: B
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'.

Synovial fluid is present in

  1. Spinal cavity

  2. Cranial cavity

  3. Freely movable joints

  4. Fixed joints

Show answer
Correct Option: C
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

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

  1. Coelomic fluid

  2. Synovial fluid

  3. Pericardial fluid

  4. Mucin

Show answer
Correct Option: B
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'.
