  1. 30

  2. 33

  3. 40

  4. 35

Show answer
Correct Option: B
Explanation:

The vertebral column in adult man comprises of 26 bones- 

Cervical vertebrae (7), Thoracic vertebrae (12), Lumbar vertebrae(5), Sacrum (5 fused bones), Coccyx (3 to 5 fused bones). 
In a child, there are 33 separate vertebrae, the 9 in the sacrum and coccyx not yet being fused.

Cervical vertebrae are characterized by the presence of

  1. Long neural spine

  2. Odontoid process

  3. Vertebral-arterial-canals

  4. None of the above

Show answer
Correct Option: C
Explanation:

There are 7 cervical vertebrae. All cervical vertebrae have apertures in their transverse processes, known as Foramina transversalis, which form vertebro-arterial-canals on either side for vertebral artery to pass through to supply brain and spinal cord.

The coxal of the pelvic girdle is formed by the fusion by

  2. Scapula and clavicle

  3. Ilium and scapula

  4. Ilium, scapula and ischium

  5. Clavicle and pubis

Show answer
Correct Option: A
Explanation:

The hip bone or innominate bone or coxal bone is a large, flattened, irregularly shaped bone. It consists of three parts, the ilium, ischium, and pubis, which are fused in the adult.

(ii) Pivot joint - Between carpal and metacarpal
(iii) Saddle joint - Between atlas and axis 
(iv) Gliding joint  - Between the carpals
(v) Fibrous joint - In flat skull bones

  1. (ii) and (iii)

  2. (i) and (iv)

  3. (v) Only

  4. (ii) Only

Show answer
Correct Option: A
Explanation:

In the given table options i and iv are correctly matched.

So, the correct option is '(i) and (iv)'.

 Match column I with column II and select the correct option from the codes given below:

Column I Column II
A. Saddle joint (i) Metacarpo-phalangeal joint
B. Gliding joint (ii) Carpometacarpal joint of thumb
C. Hinge joint (iii) Between tarsal bones
D. Ellipsoid joint (iv) Knee joint

  1. A-(i), B-(ii), C-(iii), D-(iv)

  2. A-(ii), B-(iii), C-(iv), D-(i)

  3. A-(iv), B-(iii), C-(ii), D-(i)

  4. A-(iii), B-(ii), C-(iv), D-(i)

Show answer
Correct Option: B
Explanation:
 Column I  Column II
 Saddle joint  Carpometacarpal joint of the thumb
 Gliding joint between tarsal bones
 Hinge joint  Knee joint
 Ellipsoid joint   Metacarpophalangeal joint
   

So, the correct option is 'A-(ii), B-(iii), C-(iv), D-(i)'.

Hips are attached to

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

  1. scapula

  2. sternum

  3. clavide

  4. ilium

Show answer
Correct Option: D
Explanation:

The pelvic girdle is located in the lower part of the trunk. It consists of three bones that are upper ileum, lower ischium and inner pubis, they fuse to form a stout hip bone. Ventral wall of the pubis has a small bone which is known as cotyloid. The acetabulum is formed by ilium, ischium and pubis, but in mammals, pubis is replaced by cotyloid bone.

So, the correct option is 'ilium'

Match the two columns and select the correct option from the codes given below.

The joints between the carpal bones are:

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

  1. gliding joints

  2. hinge joints

  3. saddle joints

  4. pivot joints

Show answer
Correct Option: A
Explanation:

The joints between the carpal bones are 'gliding joints'.

Elbow joint is an example of .......... type of joint.

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

  1. Ball and socket

  2. Gliding

  3. Hinge

  4. Pivot

Show answer
Correct Option: C
Explanation:
In hinge joints, the articulating ends of the bones fit together like a hinge on a door, and movement is therefore restricted to flexion and extension (movement only in one plane). 
The elbow joint is an example, which permits only flexion and extension of the forearm. Other examples of hinge joints are knee joint, ankle joint and joints between the phalanges of the fingers and the toes.
So, the answer is C.
