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

Joint between carpal and metacarpal of human thumb is an example of

  1. Hinge joint

  2. Saddle joint

  3. Gliding joint

  4. Pivot joint
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. 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'.

A 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. 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'.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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'.

The ball and socket type of joint is also called

  1. Shindylesis

  2. Rotataria

  3. Enarthrose

  4. Ginglymus
Reveal answer Fill a bubble to check yourself
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. 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'.

Hinge joint is present in our body between

  1. Thumb and trapezium

  2. Humerus and scapula

  3. First and second vertebra

  4. Humerus and radio-ulna
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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.

A pivot joint can be found between

  1. Clavicle and sternum

  2. Radius and ulna

  3. Scapula and humerus

  4. Tibia and fibula
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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.

So, the correct option is 'radius and ulna'.

Which of the following diarthrotic joints allows for the greatest degree of movement?

  1. Ball and socket

  2. Pivot

  3. Hinge

  4. Gliding
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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.

So, the correct option is 'Ball and socket'.

Which one of the following is mismatched?

  1. Slightly movable joint-vertebrae

  2. Hinge joint-hip

B Correct answer
Explanation
 Slightly movable joint  Vertebrate
 Hinge joint  Femur of leg
 Synovial joint  Elbow
 Immovable joint  Suture in cranium

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

True joint are

  1. Synchondroses

  2. Syndesmoses

  3. Synovial

  4. Ball and socket
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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.

Which of the following pair is correctly matched?

  1. Cartilaginous joint - skull bones

  2. Hinge joint - between vertebrae

  3. Fibrous joint - between phalanges

  4. Gliding joint - between zygapophyses of the successive vertebrae
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • 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'.

When a joint allows restricted movement in one plane only, it is known as a

  1. Hinge joint

  2. Gliding joint

  3. Angular joint

  4. Pivot joint
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The hinge joint is a joint in which a convex part of one bone fits into a concave part of another, allowing motion in only one plane. In hinge joint, the two bones open and close in one direction only (along one plane) like a door, such as a knee joint.

So, the correct answer is 'Hinge joint'

Example of pivot joint is

  1. Atlanto-axial joint

  2. Shoulder joint

  3. Hip joint

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pivot joint is a synovial joint, which permits uniaxial movement of bone about one axis of rotation. In pivot joint central bony pivot is surrounded by collar of bone and ligament. The movements possible are supination, pronation and rotation. Examples of pivot joints are proximal radioulnar joint and atlanto-axial joint.

A joint between humerus and radio Ulna is

  1. Ball and socket

  2. Pivot

  3. Gliding

  4. Hinge
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The humerus and the radioulna together form the elbow which is the hinge joint. The distal end of the humerus articulates the proximal end of the radius and ulna. The humeroulnar joint is also a part of the elbow and is a hinge joint whereas the proximal radioulnar and the distal radioulnar is a pivot joint. Thus, the correct answer is option D.
