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

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 fold or extend. The elbow is a more complex hinge joint that forms between the humerus of the upper arm and the ulna and radius of the forearm. So, the correct answer is 'Hinge'.

Ulna is a

  1. Long and curved bone

A Correct answer
Explanation
  • The bones of the hand (forelimb) are humerus, radius and ulna, carpals (wrist bones – 8 in number), metacarpals (palm bones – 5 in number) and phalanges (digits – 14 in number),
  • The ulna is a long and curved bone.
  • Proximally, the ulna articulates with the humerus at the elbow joint. Distally, the ulna articulates with the radius, forming the distal radio-ulnar joint.
  • So, the correct answer is 'Long and curved bone'.

Acetabulum is formed at the point of fusion of bones

  1. Ilium, Ischium

  2. lschium and pubis

  3. Ilium, pubis

  4. Ilium, Ischium, pubis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

There are three bones of the hip bone that come together to form the acetabulum. Two-fifths of the structure is the ischium, which provides lower and side boundaries to the acetabulum. The ilium forms the upper boundary, providing a little less than two-fifths of the structure of the acetabulum. The rest is formed by the pubis, near the midline.

So, the correct option is 'Ilium, Ischium, Pubis'.

Identify the joints, which are freely movable.

  1. Fibrous joints

  2. Symphyses

  3. Synovial joints

  4. Cartilaginous joints
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A synovial joint is a connection between two bones consisting of a cartilage lined cavity filled with fluid. Synovial joints are capable of the greatest movement. Knees, elbows and shoulders are examples of synovial joints. Since they allow for free movement, synovial joints are classified as diarthrosis. They allow for many types of movement including gliding, angular, rotational etc. So, the correct answer is 'Synovial joints'.

Which of the following is an immovable joint?  

  1. Joint in the arm

  2. Joints between teeth

  3. Joint between vertebrae

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

There are several examples of these joints in the human body, including joints between the bones of the skull, joints in the pelvis and joints between the teeth and the mandible, or lower jaw, and the maxilla, or upper jaw. Another name for immovable joins is a synarthrosis, which simply means immovable. The two types of immovable joints are fibrous joints and cartilaginous joints.

Therefore, (b) is the correct answer.

Major functions of skeleton are

  1. Support

  2. Protection

  3. Storage of ions

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The skeleton serves a number of functions in vertebrates:

(1) The skeleton forms a rigid framework, which gives support to the body against gravity.
(2) The skeleton encloses the more vital organs of the body to protect them from injury.
(3) Bones contain deposits of calcium phosphate and calcium carbonate. These may be released into the blood if needed for use elsewhere in the body, but are later replaced. This helps in regulating calcium and phosphorus level of blood. 
So, the correct answer is option D.
