Multiple choice zoology movement and locomotion in man bones and movements our skeletal system and the skin human skeleton system

Half of pelvic girdle is known as 

  1. Os-innominatum

  2. Ilium

  3. Synsacrum

  4. Suspensorium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Os Innominatum is a large irregular bone that forms the bony pelvis. Os-innominatum is also called as hip bone. Each pelvic girdle is made of a pair of hip bones which are identical with each other and each made of pubis, ilium and ischium. So, the correct answer is 'os innominatum'.

Ilium is the part of

  1. Small intestine

  2. Pectoral girdle

  3. Pulmonary tract

  4. Pelvic girdle
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones i.e each half of pelvic girdle is made up of ilium, ischium, and pubis.
  •  At the point of fusion of the ilium, ischium and pubis bones there is a cavity called acetabulum to which the thigh bone (femur) articulates. Hence ilium is the part of pelvic girdle.
  • So,the correct answer is 'Pelvic girdle'.

Obturator foramen occurs in

  1. Pelvic girdle

  2. Pectoral girdle

  3. Cranium

  4. Vertebrae
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The pelvic girdle is formed by a pair of bone which is the hip bone or coxal bone. The large opening in the anteroinferior hip bone between the ischium and pubis is the obturator foramen through which nerves and blood vessels pass. So, the correct answer is 'Pelvic girdle'.

Two halves of pelvic girdle are joined together by

  1. Pubic symphysis

  2. Ischiac symphysis

  3. Ischibpubic symphysis

  4. By fusion
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Each pelvic girdle is composed of two hip bones. Pubic symphasis is a specialized joint where the pubis of one hip bone joins with the pubis of opposite hip bone. So the two halves of pelvic girdle are joined together by pubic symphasis. So, the correct answer is 'Pectoral girdle'.

Number of bones in hindlimb of human is

  1. 21

  2. 24

  3. 30

  4. 14
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • The bones of the limbs(forelimb and hindlimb) along with their girdles (pectoral and pelvic) constitute the appendicular skeleton.
  • The bones of the hind limb are 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). Hence number of bones in the hind limb of human is 30.
  • So, the correct answer is '30'.

Socket in pelvic girdle in which head of femur articulates is formed by fusion of

  1. Ischium and pubis

  2. Ilium and pubis

  3. Ilium, and ischium

  4. Ileum, ischium and pubis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The pelvic girdle consists of paired hip bones each is made up of three bones which are ilium, ischium and pubis. These three bones unite in early adulthood at a triangular suture in the acetabulum and form the cup-shaped socket that forms the hip joint with the head of the femur (thigh bone). So, the correct answer is 'Ileum, ischium and pubis'.

Acetabulum is a part of

  1. Pelvic girdle

  2. Pectoral girdle

  3. Fore arm

  4. Upper arm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones i.e each half of pelvic girdle is made up of ilium, ischium, and pubis.
  •  At the point of fusion of the ilium, ischium and pubis bones there is a cavity called acetabulum to which the thigh bone(femur) articulates. Hence acetabulum is a part of the pelvic girdle.
  • So, the correct answer is 'Pelvic girdle'.

Part of the body having a single pair of bones is

  1. Pelvic girdle

  2. External ear

  3. Wrist

  4. Lower Jaw
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The pelvic girdle consists of a single pair of bones, called hip bones. They are connected at the front by cartilage called the pubic symphysis and they are attached to the sacrum at the back. Each hip bone is made up of three bones which are ilium, ischium and pubis. So, the correct answer is 'Pelvic girdle'.

Multiple choice zoology movement and locomotion in man bones and movements our skeletal system and the skin human skeleton system

Common to kidney and skeleton in mammals is

  1. Cortex

  2. Medulla

  3. Radius

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

  • The term 'pelvis' is common to both kidney and skeleton in mammals. In relation to the kidney, 
  • It can be described as a chamber in the kidney into which the urine drains from renal tubules before passing to the ureter. 
  • For skeleton, it is related to a pelvic girdle or hip girdle. Hence, Pelvis is Common to kidney and skeleton in mammals.
   So, the correct answer is 'pelvis'.

Identify the mismatch.

  1. Sternum and ribs $\rightarrow$ Axial skeleton
  2. Clavicle and glenoid cavity $\rightarrow$ Pelvic girdle
  3. Humerus and ulna $\rightarrow$ Appendicular skeleton
  4. Malleus and stapes $\rightarrow$ Ear ossicles
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • A pectoral girdle or shoulder girdle attach the bones of upper limb to the axial skeleton.
  • Each pectoral girdle is formed of two halves. Each half of pectoral girdle consists of a scapula and clavicle. 
  • Glenoid cavity is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. It articulates with the humerus to form the shoulder joint. Hence clavicle and glenoid cavity → pectoral girdle.
  • So, the correct answer is 'Clavicle and glenoid cavity $\rightarrow$ Pelvic girdle'.
