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

How many types of synovial joints are there?

  1. 4

  2. 3

  3. 2

  4. 5
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'.

Choose the correct answer from the alternatives given.
What is the synovial membrane which protects lungs from friction against abdominal wall?

  1. Pleura

  2. Mesentery

  3. Alveolar septum

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

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'.

Which one of the following is mismatched?

  1. Slightly movable joint-vertebrae

  2. Hinge joint-hip

  3. Synovial joint-elbow

  4. Immovable joint-sutures in cranium
Reveal answer Fill a bubble to check yourself
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'.

Choose the correct answer from the alternatives given.
Equilibrium and activities of the muscles and Joints are monitored by

  1. proprioceptors

  2. tactile receptors

  3. receptory receptors

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

(A)Propioceptor responds to activities of muscles and joints.

(B)Tactile receptors responds to touch.
(C)Receptory receptors respond to the specific receptor.
(D)Gustatory receptors respond to taste.
So, the correct option is 'propioceptor'.

Axis is different from atlas in the

  1. Presence of odontoid process

  2. Presence of central cavity

  3. Absence of central cavity

  4. Presence of neural cavity
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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.
