Forensic Anthropologist Web License Quiz

Explanation
The number of fused bones can be used to determine the age of a skeleton because as a person ages, certain bones in the body fuse together. This process, known as ossification, occurs gradually over time, and the number of fused bones increases with age. By examining the skeleton and counting the number of fused bones, it is possible to estimate the age of the individual.

Explanation
Female skeletons typically have a wider pelvis compared to male skeletons. This is because the female pelvis is adapted for childbirth, requiring a larger birth canal to accommodate the passage of a baby's head. The wider pelvis allows for easier delivery of the baby during childbirth. Additionally, the female pelvis is generally broader and more rounded to provide stability and support for the reproductive organs.

Explanation
The femur, or thigh bone, is the longest and strongest bone in the human body. It is commonly used to determine the height of the deceased because its length is directly proportional to a person's height. By measuring the femur, forensic experts can estimate the individual's height, which can be crucial in identifying the deceased in cases where only skeletal remains are present. The femur is a reliable indicator of height due to its consistent length and its role in supporting the body's weight.

Explanation
The statement "You can tell if a person is right or left handed from their bones" is false. While certain bones may show signs of asymmetry due to repetitive movements associated with handedness, it is not possible to definitively determine a person's handedness solely based on their bones. Handedness is a complex trait influenced by a combination of genetic, environmental, and cultural factors. Thus, it cannot be accurately determined by examining bones alone.

Explanation
Wearing at joints at certain points on the skeleton can give you clues about the person's weight because excessive weight and pressure on the joints can cause them to wear down over time. The wear patterns can indicate the amount of stress that the joints have been subjected to, which is often correlated with body weight. Therefore, analyzing the wear on joints can provide insights into the person's weight.

Explanation
The sciatic notch is located between the pelvic bones. The sciatic notch is a large notch on the posterior aspect of the pelvis, formed by the ischium and the ilium bones. It serves as a passageway for the sciatic nerve, which is the longest and thickest nerve in the body. The sciatic nerve runs from the lower back down through the buttocks and into the legs. Understanding the location of the sciatic notch is important in anatomy and medical fields, as it helps in identifying and diagnosing issues related to the sciatic nerve.

Explanation
A forensic anthropologist can use the width of a notch on the pelvis to determine the gender of an individual. The pelvic notch, also known as the subpubic angle, is wider in females compared to males. By using his thumb to measure the width of this notch, the anthropologist can make an educated guess about the gender of the individual. This method is based on the anatomical differences between male and female pelves, and it can provide valuable information in forensic investigations.

Explanation
The sagittal suture in the skull can be investigated to determine age. The sagittal suture is a fibrous joint that connects the two parietal bones of the skull. As a person ages, this suture gradually fuses and becomes less visible. By examining the degree of fusion or closure of the sagittal suture, forensic anthropologists and archaeologists can estimate the age of an individual. This method is particularly useful in determining the age of skeletal remains when other methods, such as dental analysis or growth plates, are not available.

Explanation
A forensic entomologist studies insects on a corpse to determine various aspects of a crime scene, such as the time of death, location, and potential presence of drugs or toxins. Insects are attracted to decomposing bodies and go through predictable stages of colonization, which can provide valuable information to investigators. By analyzing the types and life cycles of insects found on a corpse, a forensic entomologist can help establish a timeline and gather evidence to aid in solving a crime.

Explanation
The jaw of a female is round compared to a male. This is because females tend to have softer facial features, and a round jawline is often considered more feminine. On the other hand, males typically have a more square or angular jawline, which is associated with a more masculine appearance.

Explanation
Due to genetic and ethnic differences, the skull of an African-American individual is often characterized by a wider eye orbital compared to that of a Caucasian individual. This variation in eye orbital width is a result of differences in facial structure and bone development between different racial and ethnic groups.

Explanation
Forensic anthropology is the correct answer because it is the field of science that specializes in the identification and analysis of skeletal remains. This involves examining bones to determine the age, sex, ancestry, and other characteristics of the individual. Forensic anthropologists use their knowledge of human anatomy and skeletal biology to assist in criminal investigations, identify unknown individuals, and provide information for legal proceedings. Reconstruction anatomy and physiology are not specifically focused on identifying skeletal remains, making forensic anthropology the most appropriate field in this context.
