Incomplete Bleeding Due to Medulla Oblongata Damage
View Complete Answer & Explanation
Question (English)
In which of the following methods of ritual slaughter does bleeding remain incomplete due to damage of medulla oblongata?
- Jhatka & Halal method
- Jhatka & Evernazine method ✓ Correct
- Halal & Jewish method
- Only Jhatka method
Explanation:
Correct Answer: Jhatka & Evernazine method
In both the Jhatka method and the Evernazine method, bleeding remains incomplete because the medulla oblongata is damaged/severed during slaughter.
Why Medulla Oblongata Damage Causes Incomplete Bleeding
The medulla oblongata controls the cardiovascular centre (heart rate and vasomotor tone). When it is severed/damaged, the heart stops pumping effectively, so blood cannot be fully expelled from the carcass — resulting in incomplete bleeding (blood remains in meat).
Slaughter Methods — Bleeding Completeness
- Halal method: Jugular veins & carotid arteries severed → complete bleeding → best blood drainage
- Jewish method (Schechita): Similar to Halal → complete bleeding
- Jhatka method: Neck severed in one stroke → medulla damaged → incomplete bleeding
- Evernazine method: Puntilla severs occipito-atlantal joint + medulla → incomplete bleeding
