Typical position of knot in method of asphyxial death shown in photograph above is Occiput.
Hanging is best defined as the constriction of neck by a ligature tightened by the weight of the body. When the point of suspension is over the center of occiput, there is a maximum possibility of occlusion of the arteries and this is known as typical hanging, while all other points of suspension are called atypical hanging .
In hanging from a high point of suspension, the victim is either fully suspended, with his feet clean off the ground or he is suspended with his knees slightly flexed.
In hanging from a low point of suspension (Partial Hanging), a comparatively little force, about 4.5 kg is enough to occlude blood vessels of the neck. The term Partial Hanging is used for such cases in which the bodies are partially suspended, or for those in which bodies are in a sitting, kneeling reclining, prone or any other posture
