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'.

Human vertebral column consists of 33 vertebrae and______bones.

  1. 33

  2. 26

  3. 27

  4. 29

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'.

In thoracic cavity of man which one is present

  1. Lungs only

  2. Lungs + Heart

  3. Lungs + heart + stomach

  4. Hearts only

B Correct answer
Explanation
The thoracic cavity is also known as the chest cavity. It is a chamber in the body of the animal that is protected by the ribcage, skin and the muscles.
The essential organs that are present in the thoracic cavity are the lungs, the heart, a small part of the oesophagus and various lymph nodes and blood vessels.
So, the correct option is 'lungs+heart'

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

B Correct answer
Explanation

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