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

Identify the joint(s) that comes under synovial joints.

  1. Ball and socket joint

  2. Pivot joint

  3. Hinge joint

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A synovial joint is a connection between two bones which consists of a cartilage lined cavity filled with fluid. There are six types of synovial joints and they are pivot, hinge, saddle, plane, condyloid and ball and socket joints. So, the correct answer is 'All of the above'.

Joint between atlas and odontoid process of axis is

  1. Pivot joint

  2. Saddle joint

  3. Angular joint

  4. Hinge joint
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The atlas is the first cervical vertebra which is just under the head. The axis is the second cervical vertebra. It has the odontoid process about which the atlas rotates. The joint between the atlas and axis is a pivot type of joint. The pivot joint is a freely moveable joint that allows only rotary movement around a single axis. It allows the head to turn from side to side. So, the correct answer is 'Pivot joint'.

Fabellae are associated with

  1. Elbow joint

  2. Knee joint

  3. Neck joint

  4. Angular joint
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The fabella is a small sesamoid bone that is found embedded in the tendon of the lateral head of the gastrocnemius muscle behind the lateral condyle of the femur.
  • The femur meets the large shin bone (the tibia) to form the knee joint. Hence fabellae are associated with the knee joint.
  • So, the correct answer is 'Knee joint'.

Which of the following is correctly matched?

  1. Gliding joint- Between zygapophyses of successive vertebrae

  2. Hinge joint- Between vertebrae

  3. Cartilaginous joint- Skull bones

  4. Fibrous joint- Between phalanges
Reveal answer Fill a bubble to check yourself
A 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 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'.

Number of ball and socket joints present in human body is

  1. 2 pairs

  2. 4 pairs

  3. 6 pairs

  4. 8 pairs
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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'.

Which of the following is a ball and socket joint?

  1. Knee joint

  2. Elbow joint

  3. Humerus and pectoral girdle

  4. Skull and atlas
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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'.

Ankle joint is

  1. Pivot joint

  2. Ball and socket joint

  3. Hinge joint

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

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'.

Which one of the following is not a synovial joint?

  1. Ball and socket joint

  2. Pivot joint

  3. Sutures forming the cranium

  4. Hinge joint
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • 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'.

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'.

Which among the following are synovial joints?
1.Ball and socket joint
2.Pivot joint
3.Hinge joint 
4.Cartilaginous joint

  1. 1, 2, and 3

  2. 1 and 2

  3. 2 and 4

  4. 1 and 3
Reveal answer Fill a bubble to check yourself
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'.
