In hanging deaths, the atypical (incomplete, partial) hanging differs from typical hanging in which histological feature of the internal neck structures?

• A Atypical hanging more frequently shows fracture of the thyroid cartilage
• B Typical hanging from a height shows intimal tear of the carotid arteries due to neck hyperextension forces
• C Atypical hanging more often shows petechial haemorrhages in the conjunctivae than typical hanging ✓
• D Typical hanging is associated with higher prevalence of Paltauf's haemorrhage

Explanation

In typical hanging (body fully suspended with the knot at the occiput), death occurs rapidly from carotid artery/jugular vein compression causing cerebral ischaemia and simultaneously stimulating carotid sinus causing vagal arrest — with rapid loss of consciousness and minimal venous congestion above the ligature, resulting in fewer or absent conjunctival petechiae. In atypical (partial, incomplete) hanging where the feet or knees touch the ground and incomplete suspension occurs, venous return is incompletely obstructed but arterial supply continues, creating more intense facial congestion and petechiae in the conjunctivae. Carotid intimal tears are associated with judicial hanging or falls with neck hyperflexion.
