For example, human body height is to be the length of eight heads, with an additional one-quarter head for neck length. Leg length is to be four head lengths. [1] Forensic estimation of stature is part of the identification process necessary when dismembered body parts are found. It is also possible to estimate the stature from bones. [2]
The intermembral index is a ratio used to compare limb proportions, expressed as a percentage. [1] It is equal to the length of forelimbs (humerus plus radius) divided by the length of the hind limbs (femur plus tibia) multiplied by 100, [2] otherwise written mathematically as:
The femur is the largest and thickest bone in the human body. It is considered the strongest bone by some measures, though other studies suggest the temporal bone may be stronger. On average, the femur length accounts for 26.74% of a person's height, [4] a ratio found in both men and women across most ethnic groups with minimal
Third-trimester obstetric ultrasonography (head circumference, femur length) ±8% of the estimate As a general rule, the official gestational age should be based on the actual beginning of the last menstrual period, unless any of the above methods gives an estimated date that differs more than the variability for the method, in which case the ...
Above, the linea aspera is prolonged by three ridges. The lateral ridge is very rough, and runs almost vertically upward to the base of the greater trochanter.It is termed the gluteal tuberosity, and gives attachment to part of the gluteus maximus: its upper part is often elongated into a roughened crest, on which a more or less well-marked, rounded tubercle, the third trochanter, is ...
Bone growth in length is stimulated by the production of growth hormone (GH), a secretion of the anterior lobe of the pituitary gland. The long bone category includes the femora, tibiae, and fibulae of the legs; the humeri , radii , and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the phalanges of the fingers and toes ...
Aspects commonly studied in determining the species of very early skeletons include the length of the femur and other long bones, the capacity of the skull, the shape of the facial features and skull, the shape of the jaw and teeth, the curve of the spine, the situation and shape of the pelvis, and the location of the foramen magnum.
Ultrasonography involves an algorithm that incorporates biometric measurements of the fetus, such as biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL), to calculate the estimated fetal weight (EFW). [32]
