B Correct answer
Explanation

It is correct. Ball and socket joint: One end of a bone is rounded and ball-like, and fits into a cup-like depression of the other bone. This joint provides movement in any direction. Shoulder joints and hip joints are examples. In the shoulder joint, the head of the humerus fits into a socket of the shoulder girdle. In the hip joint, the large ball-like head of the femur fits into the deep socket of the hip girdle.

Multiple choice

Directions: Identify the type of joint after carefully reading the given clues.

  1. One bone rotates over the end of the other bone.
  2. Its example-the skull rotates on the upper end of the back bone, as an example.

  1. Pivot joint

  2. Fixed joint

  3. Stifle joint

  4. Ball and socket joint

  5. Hinge joint

A Correct answer
Explanation

Yes, in the pivot joint one bone rotates over a pivot-like end of the other bone. Just like the skull rotates on the upper end of the back bone.

Multiple choice

Directions: Identify the type of joint after carefully reading the given clues.

  1. This joint moves in one plane or one direction only.
  2. They usually give sufficient power, because there is less danger of twisting at the joint.
  3. The joints between the bones of the fingers and toes, are an example.

  1. Stifle joint

  2. Ball and socket joint

  3. Hinge joint

  4. Pivot joint

  5. Fixed Joint

C Correct answer
Explanation

Yes, hinge joint moves like a hinge in one plane only, just like the hinge of a door. The elbow joint between the humerus and the ulna and the joints between the bones of the fingers and toes are examples of this joint.

Multiple choice

Which of the following body parts have cartilage?

  1. Legs and feet

  2. Skin

  3. Nose and ears

  4. Intestines

  5. Skull

C Correct answer
Explanation

It is correct. Cartilage is a soft bone tissue that connects joints. It is present in external parts like the ear and nose.

Multiple choice

  1. 400

  2. 200

  3. 120

  4. 206
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An adult human skeleton typically contains 206 bones. These include the skull, vertebral column, rib cage, and bones of the limbs. This number is standard for healthy adults, though babies are born with around 270 bones that fuse together during growth and development.

Multiple choice

Shortest bone in the human body:

  1. Leg bone

  2. Jaw bone

  3. Nose bone

  4. Ear bone

D Correct answer
Explanation

The stapes is one of the three ossicles (tiny bones) in the middle ear and measures approximately 2-3mm in length. It is the smallest and lightest bone in the entire human body, transmitting sound vibrations from the incus to the inner ear.

Multiple choice

In which of the following disorders, bones are characterised by lesions, inflammation, and pain?

  1. Chronic inflammatory demyelinating polyneuropathy

  2. Chronic recurrent multifocal osteomyelitis

  3. Churg-Strauss syndrome

  4. Cicatricial pemphigoid

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

Chronic recurrent multifocal osteomyelitis is a rare condition in which the bones have lesions, inflammation, and pain. Its definition is evolving. It is an autoimmune disease that has symptoms similar to osteomyelitis, but without the infection.
