A gliding joint is a common type of synovial joint formed between bones that meet at flat or nearly flat articular surfaces. Gliding joints occur between the carpal bones, between the tarsal bones and those between the articular processes (zygapophyses) of successive vertebrae. So, the correct answer is 'Gliding joint- Between zygapophyses of successive vertebrae'.

The ball and socket joint is a type of synovial joint in which the ball shaped surface of one rounded bone fits into the cup like depression of another bone. There are 2 pairs of ball and socket joints present in human body. One is in the hip, where the round head of the femur rests in the cup like acetabulum of the pelvis and another in the glenohumeral joint of the shoulder, where the rounded head of the humerus rests in the cup like glenoid fossa of the shoulder blade. So, the correct answer is '2 pairs'. 

The glenohumeral joint is the articulation between the head of the humerus and the glenoid cavity of the scapula or pectoral girdle. It is a ball and socket type of synovial joint that allows for lateral rotation, flexion and extension of the arm. So, the correct answer is 'Humerus and pectoral girdle'.

The ankle joint is the joint between the foot and the leg and it is a type of hinge joint. 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. So, the correct answer is 'hinge joint'.

• Joints are points of contact between bones, or between bones and cartilages.
  
• A suture is a type of fibrous joint that is only found in the skull(cranial bones+facial bones). 
• Sutural joints are present between cranial bones of the skull.
• Hence sutures forming cranium is not a synovial joint.It is a fibrous joint.
• So, the correct answer is 'Sutures forming cranium'.

• 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. Saddle joint is a type of synovial joint.
• The saddle joint gets its name because the bone forming one part of the joint is concave (turned inward) at one end and looks like a saddle. The other bone's end is convex (turned outward), and looks like a rider in a saddle.
  
• The joint between carpal and metacarpal of human thumb is an example of saddle joint.
  
• So, the correct answer is 'Saddle 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. Ball and socket joint is a type of synovial joint.
• Synovial joints are of following types: pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints. Hence ball and socket joint, pivot joint, hinge joint are synovial joints.
• So, the correct answer is '1,2 and 3'.

A synovial joint is a connection between two bones consisting of a cartilage lined cavity filled with fluid. There are five types of synovial joints. These are planar joints, hinge joints, condyloid joints, saddle joints and ball and socket joints. So, the correct answer is '5'.

• 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. Ball and socket type of joint is a type of synovial joint.
• In the ball and socket joint the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. Enarthrose refers to articulation with spherical surfaces allowing the bones to move in all directions.
• Hence ball and socket type of joint is also called enarthrose.
• So, the correct answer is 'Enarthrose'.
