Comminuted fractures are those in which

  1. A bone breaks into many pieces and some of the pieces are without blood circulation.

  2. A bone breaks into two parts.

  3. A bone breaks into many parts.

  4. A small piece of bone breaks.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • A fracture is a medical condition in which there is a partial or complete break in the continuity of the bone.
  • Comminuted fractures are those in which a bone breaks into many pieces and some of the pieces are without blood circulation.
  • These types of fractures occur after high impact trauma such as vehicular accidents.
  • These types of fractures take a minimum of 3 months to recover.
  • So, the correct answer is ''A bone breaks into many pieces and some of the pieces are without blood circulation'.

Dislocation is a disease caused by

  1. Biological agent

  2. Mechanical agent

  3. Physical agent

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

Dislocation is a disease which occurs when there is an abnormal separation in the joint, where two or more bones meet. Most common sites of dislocation are shoulder, hip, patella, ankle and fingers. Dislocations are often caused by sudden trauma on the joint like an impact or fall. Mechanical agents are the major cause of dislocation, sprains, injuries, fractures etc.

So, the correct answer is 'Mechanical agent'.

At times ligaments and tendons are overstretched or torn. The phenomenon is 

  1. Sprain

  2. Dislocation

  3. Fracture

  4. Tension
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The bands of fibrous tissue that connect bones to bones at joints are called as Ligaments and which connect muscles to the bones are called as tendons.
  • At times ligaments and tendons are overstretched or torn. The phenomenon is called a sprain.
  • Sprain happen most often in the ankle but can occur at any joint, such as the wrist or knee.”
  • So, the correct answer is a 'Sprain'.

Sprain involves

  1. Overstretching of ligament

  2. Overstretching of tendon

  3. Dislodging of bone

  4. Both A and B
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A sprain is a stretching or tearing of ligaments which are the tough bands of fibrous tissue that connect two bones together in the joints. The most common causes of sprains are falling, twisting etc. These types of injuries may cause the joint to move out of its normal range of movement that causes the tearing or stretching of the ligament. So, the correct answer is 'Overstretching of ligament'.

Dislocation of bones occurs in persons who have met with and met in accidents due to the

  1. Tendon break

  2. Break of skeletal muscle

  3. Ligament break

  4. Areolar tissue break
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The ligament is the connective tissue which attaches two or more bones together to form a joint. When the ligament breaks, the two bones cannot be held together and dislocate. Generally, when the person met with an accident and the ligament is broken, there are chances that the person will suffer from the dislocation of the bones. 

Thus, the correct answer is option C.

In Human beings, the cranium is formed by

  1. Eight bones of which two are paired

  2. Fourteen bones of which six are paired

  3. Ten bones of which two are paired

  4. Twelve bones of which four are paired
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The human cranium consists of 8 bones: frontal (1), parietal (2), temporal (2), occipital (1), sphenoid (1), and ethmoid (1). This totals 8 bones with two pairs (parietal and temporal).

Which of the following body part has more number of bone that others?

  1. Skull

  2. Chest

  3. Forelimb

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

The human skeleton is the internal framework of the body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. 

So, the correct option is ‘Skull’.

Which joint is more flexible in males than females?

  1. Public symphysis

  2. Deltoid ridge

  3. Deltoid tuberosity

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

The hip girdle is located in the lower part of the trunk. 

It is made up of three bones that are upper ileum, lower ischium and the pubis.
The acetabulum is formed by ileum, ischium and pubis but in mammals, the pubis is replaced by the cotyloid bone.

The pubic symphysis is present in mammals. The two innominate bones and sacrum together form a sort of bowel.
This is also an adaptation for the upright posture of the human body. The female pelvis is larger and has a broader front and larger bottom opening than the male pelvis. This is an adaptation for childbirth.

So, the correct option is 'Public symphysis'
