Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
The human-body model (HBM) is the most commonly used model for characterizing the susceptibility of an electronic device to damage from electrostatic discharge (ESD). The model is a simulation of the discharge which might occur when a human touches an electronic device.
Evolution of the mesh for the human model: A first universal mesh prototype (head only), done in 1999 using makeHead script, was adapted for the early MakeHuman in 2000. The first professional mesh (HM01) for a human model was realized by Enrico Valenza in 2002. A second remarkable mesh (K-Mesh or HM02) was modelled by Kaushik Pal in 2003.
Body proportions is the study of artistic anatomy, which attempts to explore the relation of the elements of the human body to each other and to the whole. These ratios are used in depictions of the human figure and may become part of an artistic canon of body proportion within a culture.
The human body is the entire structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organs and then organ systems . The external human body consists of a head , hair , neck , torso (which includes the thorax and abdomen ), genitals , arms , hands , legs , and feet .
CT scans give the human body a large dose of ionizing radiation – something the computational phantom was designed to circumvent in the first place. MRI images take a long time to process. Furthermore, most scans of a single subject cover only a small portion of the body, whereas a full scan series is needed for useful data.
The model may show the anatomy partially dissected, or have removable parts allowing the student to remove and inspect the modelled body parts. Some models may have changeable genital inserts and other interchangeable parts which permit a unisex model to represent an individual of either sex. [citation needed]
