Tag: joints in the human body

A hinge joint (ginglymus) is a bone joint in which the articular surfaces are moulded to each other in such a manner as to permit motion only in one plane-backward and forward-the extent of motion at the same time being considerable. The best examples of hinge joint are the inter phalangeal joints and the joint between the humerus and ulna; the knee and ankle-joints are less typical, as they allow a slight degree of rotation or of side-to-side movement in certain positions of the limb. The knee is the largest hinge joint in the human body.

The moving bone rotates within a ring that is formed from a second bone and adjoining ligaments. The pivot joint is exemplified by the joint between the atlas and the axis directly under the skull which allows for turning of the head from side to side.

Ball and socket joint is a natural or manufactured joint or couplings, such as the hip joint, in which partially spherical lies in a socket, allowing multidirectional movement and rotation.

The pleura refers to the two membranes that cover the lungs. The space between the two membranes is called the pleural cavity. It is filled with a thin, lubricating liquid called pleural fluid, which acts as a lubricant and allows the pleurae to slide effortlessly against each other by reducing friction during respiratory movements. So, the correct option is 'pleura'.

So, the correct option is 'Hinge joint-hip'.

The axis has a bony peg called the odontoid process, which sticks up through the hole in the atlas. It is this special arrangement that allows the head to turn from side to side as far as it can.

A joint in the human body is a connection between the tissues, cartilages and bones. These are classified structurally and functionally and of these, the synovial joint is one that is functionally freely movable. The pectoral girdle or the shoulder girdle which is synovial joint is made up of a set of bones, the clavicle and scapula that connects the arms to the axial skeleton on both sides. In fact, the shoulder girdle has five joints of which three are anatomical (true joint ) and two are physiological or false joints.

• A gliding joint is a common 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. For example, between zygapophyses of the successive vertebrae.
  
• Hence Gliding joint - between zygapophyses of the successive vertebrae are correctly matched.
• So, the correct answer is 'Gliding joint - between zygapophyses of the successive vertebrae'.
