Total number of bones in the hind limb of a man is

  1. 14

  2. 21

  3. 24

  4. 30


Correct Option: D
Explanation:

Each hind limb contains 30 bones namely femur in thigh, patella inthe knee, tibia and fibula in the lower leg, 7 tarsals in the ankle, 5 meta-tarsals in the sole and 14 phalanges in toes.

A cricket player is chasing a ball. Which group of muscles is contributing in this movement

  1. Femur, Malleus, Tibia, Metatarsals

  2. Pelvis, Ulna, Patella, Tarsals

  3. Sternum, Femur, Tibia, Fibula

  4. Tarsals, Femur, Metatarsals, Tibia


Correct Option: D
Explanation:
  • Hindlimb is composed of  Femur (thigh bone – the longest bone), tibia and fibula, tarsals (ankle bones – 7 in number), metatarsals (5 in number) and phalanges (digits – 14 in number).
  • When a cricket player is chasing a ball it represents he is running. during running hind limbs assist motion hence muscles off hind limbs contribute to the motion.
  • Hence when a cricket player is chasing a ball. the group of muscles which contribute to this movement are tarsals, femur, metatarsals, tibia.
  • So, the correct answer is 'Tarsals, femur, metatarsals, tibia'.

In which bones shall have Haversian system ___________.

  1. Panther

  2. Python

  3. Pigeon

  4. Pipe Fish


Correct Option: A
Explanation:

  • The osteon or Haversian system is the fundamental functional unit of much compact bone. 
  • Osteons are roughly cylindrical structures. 
  • Presence of the Haversian system is a typical character of mammalian bone. Panther is a mammal. Hence, bones of panther shall have a Haversian system.
So, the correct answer is 'panther'.

Which is the longest bone in human body?

  1. Humerus

  2. Stapes

  3. Femur

  4. Radio-ulna


Correct Option: C
Explanation:
The longest bone in the human body is the femur or thigh bone which contains about 1/4 of the height of an adult. The femur is also the strongest bone in the human body. So, the correct answer is 'Femur'.

Joint between humerus and radio-ulna is

  1. Ball and socket

  2. Pivot

  3. Gliding

  4. Hinge


Correct Option: D
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'.

Radius is bone of

  1. Arm

  2. Leg

  3. Pelvic girde

  4. Cranium


Correct Option: A
Explanation:
  • The bones of the arm or forelimb are humerus, radius and ulna, carpals (wrist bones – 8 in number), metacarpals (palm bones – 5 in number) and phalanges (digits – 14 in number).
  • Hence radius is bone of arm.
  • So, the correct answer is 'Arm'.

Ulna is a

  1. Long and curved bone

  2. Small slender bone

  3. Very small bone

  4. Very long bone


Correct Option: A
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


Correct Option: D
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'.
