. Lesion with intact skin but tearing of subcutaneous tissue is
- A.
. Scalds
- B.
. Laceration
- C.
. Contusion
- D.
. Abrasion
Correct Answer
A. . ScaldsExplanation
A scald is an injury caused by hot liquids or steam coming into contact with the skin. In this case, the lesion has intact skin, indicating that there is no break in the outer layer of the skin. However, there is tearing of the subcutaneous tissue, which is the layer of tissue beneath the skin. This tearing suggests that the injury is deeper than just the superficial layers of the skin, which is consistent with a scald.Rate this question:

Abrasion collar is seen in
- A.
. Abrasions over neck
- B.
. Bullet injury
- C.
. Punctured wounds
- D.

The presence of an abrasion collar indicates that the injury occurred due to scraping or rubbing against a rough surface. In the case of abrasions over the neck, it suggests that the person may have experienced friction or contact with a rough object around the neck area, causing the skin to be scraped off. This could be due to various reasons such as strangulation, an assault, or accidental contact with a sharp object.Rate this question:

. In India, for exhumation maximum permissible time period is
- A.
5 years
- B.
10 years
- C.
. 20 years
- D.

In India, the maximum permissible time period for exhumation is 5 years. This means that after a person is buried, their remains can only be exhumed within a period of 5 years. After this time period, exhumation is not allowed unless there are exceptional circumstances or legal requirements. This time limit ensures that the deceased's remains are given adequate time for decomposition and allows for proper burial practices to be followed.Rate this question:

- A.
. 5 years
- B.
. 7 years
- C.
. 10 years
- D.
. 12 years
Correct Answer
A. . 5 yearsExplanation
The correct answer is 5 years because it is generally accepted that children below the age of 5 do not have the cognitive and moral development to understand the consequences of their actions or to form criminal intent. This is supported by various psychological and legal frameworks that consider a certain level of maturity and understanding as necessary for criminal responsibility. Therefore, it is commonly agreed upon that children cannot be held responsible for crimes committed before the age of 5.Rate this question:

MEDICOLEGAL ASPECT OF DEATH 10. Most informative test in parental identification
- A.
. HLA
- B.
Parental likeness
- C.
Developmental defects
- D.
. DNA finger printing
Correct Answer
A. . HLAExplanation
HLA (Human Leukocyte Antigen) testing is the most informative test in parental identification. HLA genes are inherited from parents, and by comparing the HLA profiles of a child and their alleged parents, it is possible to determine if there is a biological relationship. This test is particularly useful in cases where DNA testing is not possible or inconclusive. HLA testing can provide strong evidence of parental likeness and help establish or confirm biological parentage.Rate this question:

- A.
. Electrocution in water
- B.

Electrocution in water, on the other hand, refers to the fatal injury caused by electric shock in water. It is not related to hydrocution. Therefore, the statement "Electrocution in water" is not true about hydrocution.Rate this question:

. DNA can be taken as sample from all of the following except
- A.
Hair roots
- B.
. Semen
- C.
. CSF
- D.
Buccal mucosa
Correct Answer
A. Hair rootsExplanation
DNA can be extracted from various sources for forensic analysis, such as semen, CSF (cerebrospinal fluid), and buccal mucosa (inner lining of the cheek). However, hair roots do not contain enough viable DNA for reliable testing. While DNA can be found in the hair shaft, it is typically degraded and not suitable for accurate analysis. Therefore, hair roots are not a viable sample for DNA extraction.Rate this question:

. Test used to detect blood group of blood stain
- A.
Benzidine test
- B.
Takayama test
- C.
Luminol test
- D.
Absorption elution test
Correct Answer
A. Benzidine testExplanation
The Benzidine test is used to detect the blood group of a blood stain. It involves adding a reagent called benzidine to the stain, which reacts with the hemoglobin in the blood. This reaction produces a blue-green color, indicating the presence of blood. The test is based on the fact that different blood groups have different antigens on the surface of red blood cells, and these antigens can be detected through the reaction with benzidine. Therefore, the Benzidine test is a reliable method for determining the blood group of a blood stain.Rate this question:

- C.
. In an emergency, termination of pregnancy can be done by a single doctor

Correct Answer
A. Professional secrecy has to be maintainedExplanation
In the context of medical termination of pregnancy, all of the given statements are true except for the statement that professional secrecy has to be maintained. In medical practice, professional secrecy refers to the obligation of healthcare providers to keep patient information confidential. However, in the case of medical termination of pregnancy, healthcare providers may be required to disclose certain information to ensure the safety and well-being of the patient. This may include sharing information with other healthcare professionals involved in the procedure or reporting cases of termination to relevant authorities. Therefore, professional secrecy is not always maintained in the context of medical termination of pregnancy.Rate this question:

After death, Livor mortis is caused because of:
- A.
. Muscle of the body began to relax
- B.
Muscle of the body began to stiffen
- C.
Discolouration as a result of capillo-venous distension in the dependent parts of the body
- D.
. Putrefaction of the body tissues
Correct Answer
A. . Muscle of the body began to relaxExplanation
After death, Livor mortis is caused because the muscles of the body begin to relax. Livor mortis, also known as lividity, is the pooling of blood in the dependent parts of the body due to gravity. As the muscles relax, blood is no longer being pumped through the body, causing it to settle in the lower areas. This results in a discoloration of the skin in those areas, giving a purplish appearance.Rate this question:

- B.
Cortical death following widespread brain injury
- C.
. Absence of brainstem reflexes
- D.
Core temperature of the body is below 35 degree C
Correct Answer
A. . Absent spinal reflexesExplanation
Brain death is said to occur if there are absent spinal reflexes. Spinal reflexes are involuntary movements that are controlled by the spinal cord without any input from the brain. When these reflexes are absent, it indicates that the brain is no longer functioning, leading to brain death.Rate this question:

A. . First premolarExplanation
The first permanent teeth to erupt are the first premolars. These teeth typically come in around the age of 10 to 12 years old, replacing the primary molars. The eruption of the first premolars marks an important milestone in dental development, as it signifies the transition from the primary dentition to the permanent dentition.Rate this question:

Rigor mortis occurs due to
- A.
. Muscle of the body began to relax
- B.
Capillo-venous distension in the most dependent body parts
- C.
. Muscle of the body began to stiffen
- D.
Muscle of the body began to stiffen
Correct Answer
A. . Muscle of the body began to relaxExplanation
Rigor mortis occurs due to the stiffening of muscles in the body after death. This happens because ATP, the molecule responsible for muscle contraction, is no longer being produced. Without ATP, the muscles are unable to relax and remain in a contracted state, causing stiffness.Rate this question:
