What is common among crab and honeybee?

  1. Jointed legs

  2. Metamorphosis

  3. Compound eyes

  4. Poison glands


Correct Option: A
Explanation:

Crab and honeybee, belong to the Phylum Arthropoda. The members of this phylum have characteristic feature of jointed appendages.

Which one of the following pairs of structures is correctly matched with their correct description ?

  1. Tibia and fibula Both form parts of knee joint

  2. Joint between Pivot joint atlas and axis

  3. Shoulder joint Ball and socket type of joint and elbow joint

  4. None of these


Correct Option: A
Explanation:

Tibia and fibula are two long bones in the lower leg tibia connect to the knee joint while the fibula is located below the knee joint but is not part of the joint itself, while the joint between atlas and axis is pivot type of joint.

So, the correct option is 'Joint between Pivot joint atlas and axis'.

What is the type of movable joint present between the atlas and axis ?

  1. Pivot

  2. Saddle

  3. Hinge

  4. Gliding


Correct Option: A
Explanation:

Pivot joint helps in turning movements. One bone is fixed and second articulate. This is generally seen in the Atlas and axis of the skull rotate with the axis vertebra also known as an atlantoaxial joint.

So, the correct option is 'Pivot'

Which one of the following options is incorrect ?

  1. Hinge joint between humerus and pectoral girdle

  2. Pivot joint between atlas, axis and occipital condyle

  3. Gliding Joint between the carpals

  4. Saddle joint between carpel and metacarpals of thumb


Correct Option: A
Explanation:

There are many joints present in the skeleton. Joint is a point of contact between two bones. The various type of joints present in the body are-

Ball and socket joint-
Ball of one bone articulate in the socket of another bone. Head of the humerus and glenoid cavity of the pectoral girdle,  femur and acetabulum, the joint between incus and stapes.
Hinge joint-
movement is possible in one direction only. Joint of malleus and incus, knee joint, elbow joint, articulation joint of the lower jaw.
Pivot joint- 
helps in turning moment. One bone is fixed and second articulate. Atlas and axial of skull rotate with Axis vertebra 
Gliding joint-
limited movement in all direction. Radius and ulna
Saddle joint- 
It is a ball and socket like a joint but not developed fully. Metacarpals of thumb and carples of hand.
So, the correct option is 'Hinge joint between humerus and pectoral girdle'

The joint of radio-ulna with the upper arm is:

  1. hinge joint

  2. socket joint

  3. pivot joint

  4. none of these


Correct Option: A
Explanation:

The joint of radio-ulna with the upper arm is 'hinge joint'.

So the correct option is A.

The joint in which one of the two bones is fixed in its place and bears a peg like process over which the other bone rotates is called:

  1. hinge joint

  2. saddle joint

  3. pivot joint

  4. angular joint


Correct Option: C
Explanation:

The joint in which one of the two bones is fixed in its place and bears a peg like process over which the other bone rotates is called pivot joint,

So, the correct option is 'pivot joint'.

Which of the following pairs is correctly matched ?

  1. Hinge joint Between vertebrae

  2. Gliding joint Between zygapophyses of the successive vertebrae

  3. Cartilaginous joint Skull bones

  4. Fibrous joint Between phalanges


Correct Option: B

Knee joint and elbow joints are examples of:

  1. Saddle joint

  2. Ball and socket joint

  3. Pivot joint

  4. Hinge joint


Correct Option: D
Explanation:
  • There are many joints present in the skeleton. Joint is a point of contact between two bones. The various type of joints present in the body are-
Ball and socket joint-
  • Ball of one bone articulates in the socket of another bone. Head of the humerus and glenoid cavity of the pectoral girdle,  femur and acetabulum, the joint between incus and stapes.
  • Hinge joint-
movement is possible in one direction only. Joint of malleus and incus, knee joint, elbow joint, articulation joint of the lower jaw.
  • Pivot joint- 
helps in turning moments. One bone is fixed and second articulate. Atlas and axial of skull rotate with Axis vertebra 
  • Gliding joint-
limited movement in all directions. Radius and ulna
  • Saddle joint- 
It is a ball and socket like a joint but not developed fully. Metacarpals of thumb and carpels of hand.

So, the correct option is 'hinge joint'

Which type of joint has a fluid filled cavity with significant role in locomotion?

  1. Fibrous joint

  2. Cartilaginous joint

  3. Synovial joint

  4. All of the above


Correct Option: C
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.
  • Hence the type of joint has a fluid-filled cavity with a significant role in locomotion is synovial joint.
  • So, the correct answer is 'Synovial joint'.

Joint of femur with pelvic girdle is _________.

  1. Hinge joint

  2. Pivot joint

  3. Immovable joint

  4. Ball and socket joint


Correct Option: D
Explanation:
  • Joints are points of contact between bones, or between bones and cartilages.
  •  Ball and socket joint is a type of synovial joint.
  • In ball and socket joint, the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone.
  • Pelvic girdle consists of a pair of hip bones. the hip bone is formed by the fusion of 3 bones: the ischium, ilium and pubic bone. Together, they form the acetabulum(socket), which is the area where the head of the femur(ball) articulates with the hip bone.Hence.Joint of the femur with pelvic girdle is ball and socket joint.
  • So, the correct answer is 'Ball and socket joint'.
