In birds, 6-10 caudal vertebrae are usually fused to form

  1. Sesamoid bone

  2. Odontoid process

  3. Plowshare bone

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

The body of the bird is adapted for flight. One of the key adaptions for this is the fusing of bones into single ossification.The compound structure present in the birds vertebral column is called the synsacrum and is formed by the fusion of 14 to 16 vertebrae. The last part of the synsacrum is formed by the fusion of the caudal vertebrae

Which of the following is likely to have the strongest leg bone?

  1. Jockey

  2. Swimmer

  3. Weight lifter

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

The femur, or thigh bone, is the longest, heaviest and strongest bone in the entire human body and helps support all the body's weight. The weight lifter will therefore have the strongest leg bones.

Therefore, the correct answer is option C.

Patella is a kind of

  1. Cartilage bone

  2. Membrane bone

  3. Cartilage

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

A bone which is embedded in the tendon is known as sesamoid bone. Patella is a the largest sesamoid bone which articulates with the femur (thigh bone) and covers and protects the anterior articular surface of the knee joint. 

So, the correct answer is 'Sesamoid bone'.

Epiphyseal disks, which are present at the ends of the long bones are responsible for

  1. Bone elongation

  2. Growth of thickness of the bone

  3. Remodelling the shape of bone

  4. Formation of Haversian system
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

At the ends of each long bone are present epiphyses which are covered with hyaline cartilage. The longitudinal growth of long bones is due to the endochondral ossification of the epiphyseal plate and is stimulated by the production of the growth hormone.
Therefore, the correct answer is option A.

Total number of bones in axial skeleton of man are

  1. 206

  2. 120

  3. 406

  4. 80
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate.

It consists of 80 bones and is composed of six parts; the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column.
Skull has 28 bones - 8 cranial bones, 14 facial bones and 6 ossicles of middle ear.
Hyoid is single bone.
Vertebral column consists of 26 bones - 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 1 sacrum and 1 coccyx.
Thoracic cage consists of 1 sternum and 24 ribs. 
So, the correct answer is '80'

Thoracic cage in rabbit is made up of

  1. Ribs, vertebral column and diaphragm.

  2. Ribs, diaphragm and sternum.

  3. Vertebral column, diaphragm and sternum.

  4. Ribs, vertebral column and sternum.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In mammals, like rabbit and humans thoracic vertebrae, ribs and sternum together form the rib cage. In humans, the rib cage, also known as the thoracic cage, is a bony and cartilaginous structure which surrounds the thoracic cavity and supports the pectoral girdle (shoulder girdle), forming a core portion of the human skeleton. A typical human rib cage consists of 24 ribs, the sternum (with xiphoid process), costal cartilages, and the 12 thoracic vertebrae.
