Question 1. **Which bone is part of the axial skeleton?**
A) Femur
B) Scapula
C) Sternum
D) Patella
Answer: C
Explanation: The sternum is a central component of the axial skeleton, which includes the skull,
vertebral column, and thoracic cage.
Question 2. **The epiphyseal plate is best used to estimate which of the following?**
A) Time of death
B) Biological sex
C) Age of the individual
D) Cause of death
Answer: C
Explanation: Epiphyseal plate closure occurs at known ages, allowing forensic anthropologists to
estimate skeletal age.
Question 3. **In forensic anatomy, the term “medial” refers to a location that is:**
A) Toward the midline of the body
B) Away from the midline of the body
C) Toward the head
D) Toward the feet
Answer: A
Explanation: “Medial” describes a structure situated nearer to the body's midline.
Question 4. **Which plane divides the body into right and left halves?**
A) Coronal plane
, ABMDI Demonstrating Scientific Knowledge
Ultimate Exam
B) Transverse plane
C) Sagittal plane
D) Oblique plane
Answer: C
Explanation: The midsagittal (median) plane separates the body into equal right and left portions.
Question 5. **Livor mortis typically becomes fixed after:**
A) 30 minutes
B) 2–4 hours
C) 6–12 hours
D) 24–36 hours
Answer: C
Explanation: Postmortem hypostasis becomes fixed when blood coagulates in the dependent vessels,
usually 6–12 hours after death.
Question 6. **Which of the following best describes rigor mortis?**
A) Cooling of the body after death
B) Stiffening of muscles due to ATP depletion
C) Discoloration of the skin from settling blood
D) Autolysis of internal organs
Answer: B
Explanation: Rigor mortis results from the lack of ATP, causing actin-myosin cross-bridges to lock,
leading to muscle rigidity.
Question 7. **Algor mortis is most directly affected by:**
A) Ambient temperature
B) Body mass index
C) Blood type
, ABMDI Demonstrating Scientific Knowledge
Ultimate Exam
D) Presence of clothing
Answer: A
Explanation: The rate of postmortem cooling (algor mortis) depends primarily on the surrounding
temperature.
Question 8. **Which stage of decomposition is characterized by the appearance of “marbling” on the
skin?**
A) Fresh stage
B) Bloat stage
C) Active decay stage
D) Advanced decay stage
Answer: C
Explanation: Marbling results from bacterial gases separating blood vessels during active decay.
Question 9. **The presence of maggot masses on a corpse most reliably indicates:**
A) Cause of death
B) Minimum postmortem interval (mPMI)
C) Time of year of death
D) Geographic location of death
Answer: B
Explanation: Maggot development stages correlate with time since death, allowing estimation of the
mPMI.
Question 10. **A contusion is best described as:**
A) A lacerated skin wound with irregular edges
B) A bruise caused by blunt force without skin breakage
C) A clean incision made by a sharp object
D. A fracture of bone without overlying skin injury
Answer: B
, ABMDI Demonstrating Scientific Knowledge
Ultimate Exam
Explanation: Contusions are bruises resulting from capillary damage due to blunt trauma, with intact
skin.
Question 11. **Which of the following wound characteristics suggests a defensive injury?**
A. Linear incised wound on the forearm
B. Multiple superficial abrasions on the knuckles
C. Deep stab wound to the abdomen
D. Oval-shaped laceration on the scalp
Answer: B
Explanation: Defensive injuries often appear as superficial abrasions or bruises on the hands or forearms
where a victim tries to fend off an attacker.
Question 12. **A hesitation mark is most commonly associated with:**
A. Suicide by cutting
B. Stab wound from a homicide
C. Gunshot wound entry
D. Incised wound from a surgical scar
Answer: A
Explanation: Hesitation marks are superficial, often parallel incisions on the skin indicating
indecisiveness before a self-inflicted fatal wound.
Question 13. **Which finding is most indicative of manual strangulation?**
A. Fractured hyoid bone only
B. Petechiae on the conjunctivae and facial skin
C. Ligature mark with a single knot
D. Hanging with a distinct ligature pattern
Answer: B
Explanation: Petechial hemorrhages in the eyes and facial skin result from venous congestion during
manual strangulation.
