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 normal distribution is NOT assumed nor required in the calculation of control limits. Thus making the IndX/mR chart a very robust tool. This is demonstrated by Wheeler using real-world data [4], [5] and for a number of highly non-normal probability distributions.
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.
Height measurement using a stadiometer. Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect.It is measured using a stadiometer, [1] in centimetres when using the metric system or SI system, [2] [3] or feet and inches when using United States customary units or the imperial system.
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:
Phenice suggests the ventral arc can only be found in females, therefore its presence categorises the subject as female. While a similar ridge may be found on male examples, this is easily distinguishable because it will take an alternative path. As such, the ventral arc is the most objective indicator of sex. [1]
In the most extreme population comparisons, for example, the average female height in Bolivia is 142.2 cm (4 ft 8.0 in) while the average male height in the Dinaric Alps is 185.6 cm (6 ft 1.1 in), an average difference of 43.4 cm (1 ft 5.1 in).
Cephalometric analysis depends on cephalometric radiography to study relationships between bony and soft tissue landmarks and can be used to diagnose facial growth abnormalities prior to treatment, in the middle of treatment to evaluate progress, or at the conclusion of treatment to ascertain that the goals of treatment have been met.
