Each scapula or pectoral girdle has a concave, articular surface called the glenoid cavity which articulates with the head of the humerus. The ball like the head of the humerus articulates with the glenoid cavity which creates a ball and socket joint that allows the upper limb great motility. So, the correct answer is 'Ball and socket'.

A hinge joint is a common class of synovial joint that includes the ankle, elbow and knee joints. Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend. The elbow is a hinged joint made up of three bones which are the humerus, ulna and radius. So, the correct answer is 'Humerus and ulna/radio-ulna'.

• 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. 
• The humerus is the long bone in the upper arm. It is located between the elbow joint and the shoulder. At the elbow, it connects primarily to the ulna. The type of joint between humerus and ulna is synovial joint.
• So, the correct answer is 'Humerus and ulna'.

• 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.
  
• Gliding joint is a type of synovial joint formed between bones that meet at flat or nearly flat articular surfaces. Gliding joints allow the bones to glide past one another in any direction along the plane of the joint - up and down, left and right, and diagonally.
  
• An example of the gliding joint is zygapophyses of adjacent vertebrae.
  
• So, the correct answer is 'Zygapophyses of adjacent vertebrae'.
  

• 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. 
• Joints of hip and shoulder are ball and socket joints(the head of one bone fits into the socket of another) i.e a type of synovial joints
• So, the correct answer is 'Ball and socket joint'.
  

• 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. 
• Joint pains in old people are mostly due to reduced synovial fluid.
  
• So, the correct answer is 'Reduced synovial fluid'.

• The fabella is a small sesamoid bone that is found embedded in the tendon of the lateral head of the gastrocnemius muscle behind the lateral condyle of the femur.
• The femur meets the large shin bone (the tibia) to form the knee joint. Hence fabellae are associated with the knee joint.
• So, the correct answer is 'Knee joint'.
