Skeletal and Muscular System Questions

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

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'.

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

Which of the following components is a part of the pectoral girdle?

  1. Acetabulum

  2. Glenoid cavity

  3. Ilium

  4. Sternum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The shoulder girdle or pectoral girdle is the set of bones in the appendicular skeleton which connects to the arm on each side. In humans, it consists of the clavicle and scapula. There are three joints in the pectoral girdle: sternoclavicular, acromioclavicular, and glenohumeral. 

Out of these, the glenohumeral joint joins the head of the humerus to the glenoid cavity. It’s a ball-and-socket joint that allows for a wide range of movement for the arm. 
So, the correct option is 'Glenoid cavity'.

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

Human vertebral column consists of 33 vertebrae and______bones.

  1. 33

  2. 26

  3. 27

  4. 29
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The human vertebral column  consists of 33 vertebrae: 24 presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae). The spine, also known as the vertebral column or spinal column, is a column of 26 bones in an adult body — 24 separate vertebrae interspaced with cartilage, and then additionally the sacrum and coccyx.


So the correct option is '26'.

Identify the incorrectly matched pair.  

  1. Pair of skeletal parts - Sternum and ribs

    Category - Axial skeleton

  2. Pair of skeletal parts - Clavicle and glenoid cavity

    Category - Pelvic girdle

  3. Pair of skeletal parts - Humerus and ulna

    Category - Appendicular skeleton

  4. Pair of skeletal parts - Malleus and stapes

    Category - Ear ossicles
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Clavicle and glenoid cavity are related to pectoral girdle but not pelvic girdle. So, the correct answer is (b).
