Skeletal and Muscular System Questions

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'.

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'.

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).

Pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones  (i), Ischium, and (ii) . At the point of fusion of the above bones, there is a cavity called (iii) to which the thigh bone articulates. The two halves of the pelvic girdle meet ventrally to form the pubic symphysis containing (iv) cartilage.

  1. (i) Clavicle (ii) Scapula (iii) Sternum (iv) Glenoid

  2. (i) Ulna (ii) Radius (iii) Tarsal (iv) Acromion

  3. (i) Sacrum (ii) Scapula (iii) Clavicle (iv) Glenoid

  4. (i) Ilium (ii) Pubis (iv) Acetabulum (v) Fibrous

D Correct answer
Explanation

The pelvic girdle is composed of two coxal bones, each formed by the fusion of the ilium, ischium, and pubis. The acetabulum is the cup-like cavity where these three bones meet and the femur articulates, and the pubic symphysis contains fibrous cartilage.

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

  1. Ilium, ischium and pubis

  2. Scapula and clavicle

  3. Ilium and scapula

  4. Ilium, scapula and ischium

  5. Clavicle and pubis

A Correct answer
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.
