  1. (i) and (v)

  2. (i) and (ii)

  3. (ii) and (v)

  4. (iii) and (iv)

Show answer
Correct Option: D
Explanation:

Following statements are incorrect regarding a normal human: 

(i) Patella is a cup-shaped bone covering the knee dorsally.
(ii) Scapula is a large triangular flat bone, situated on the ventral side of the thorax.
So, the correct answer (d).

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

  1. Sesamoid bone

  2. Odontoid process

  3. Plowshare bone

  4. Synsacrum

Show answer
Correct Option: D
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?

biology our skeletal system and the skin bones and movements joints in the human body joints

  1. Jockey

  2. Swimmer

  3. Weight lifter

  4. Golfer

Show answer
Correct Option: C
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

biology our skeletal system and the skin bones and movements joints in the human body joints

  1. Cartilage bone

  2. Membrane bone

  3. Cartilage

  4. Sesamoid bone

Show answer
Correct Option: D
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

biology our skeletal system and the skin bones and movements joints in the human body joints

  1. Bone elongation

  2. Growth of thickness of the bone

  3. Remodelling the shape of bone

  4. Formation of Haversian system

Show answer
Correct Option: A
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.

What is the term used for the opening or hole in a bone?

  1. Process

  2. Fossa

  3. Foramen

  4. Tubercle

Show answer
Correct Option: C
Explanation:

The foramen is the hole is an opening or groove in the bone that allows blood vessels and nerve to enter the bone. It i1s one of the several ovals or circular openings in the base of the skull.

So, the correct option is 'Foramen'.

Total number of bones in axial skeleton of man are

biology our skeletal system and the skin bones and movements joints in the human body joints

  1. 206

  2. 120

  3. 406

  4. 80

Show answer
Correct Option: D
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

biology our skeletal system and the skin bones and movements joints in the human body joints

  1. Ribs, vertebral column and diaphragm.

  2. Ribs, diaphragm and sternum.

  3. Vertebral column, diaphragm and sternum.

  4. Ribs, vertebral column and sternum.

Show answer
Correct Option: D
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. 

Vertebro-arterial canal is present in

  1. Lumbar vertebrae

  2. Cervical vertebrae

  3. Thoracic vertebrae

  4. Vertebral column

Show answer
Correct Option: B

Scapula is a large triangular flat bone situated in the dorsal part of the thorax between

biology our skeletal system and the skin bones and movements joints in the human body joints

  1. The second and fifth rib

  2. The second and seventh rib

  3. The third and sixth rib

  4. The third and eighth rib

  5. The fourth and seventh rib

Show answer
Correct Option: B
Explanation:

The scapula is commonly referred to as the shoulder blade. It connects the humerus bone of the arm to the collarbone. It is located between the second and seventh ribs.
