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


Correct Option: D
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


Correct Option: A
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


Correct Option: A
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'.

Common to kidney and skeleton in mammals is

  1. Cortex

  2. Medulla

  3. Radius

  4. Pelvis


Correct Option: D
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


Correct Option: B
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'.

Mark the odd one w.r.t girdle bones

  1. Clavicle

  2. Ischium

  3. Ileum

  4. Pubis


Correct Option: A
Explanation:

Bones in the shoulder consists of the clavicle, scapula, and coracoid.

So, the correct option is 'Clavicle'.

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

  1. Acetabulum

  2. Glenoid cavity

  3. Ilium

  4. Sternum


Correct Option: B
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


Correct Option: B
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'.

The vertebral column is connected to the pelvic girdle in the:

  1. coccygeal region

  2. sacral region

  3. cervical region

  4. lumbar region


Correct Option: B
Explanation:

The vertebral column is connected to the pelvic girdle in the 'sacral region'.

In thoracic cavity of man which one is present

  1. Lungs only

  2. Lungs + Heart

  3. Lungs + heart + stomach

  4. Hearts only


Correct Option: B
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'
