Distribution of the blood flow supplied by the vertebral artery in rats: anatomical, functional and pharmacological aspects.
In rats, the vertebral artery make only a minor contribution to the blood perfusion of the ponto-medullary area. This was measured with radioactive microspheres and was confirmed by methylmetacrylate casts and local injection of a centrally acting hypotensive drug.
