Segment 1 The intertitles describe the basilar artery. A tracheal cannula is inserted into the artery of an anaesthetised rabbit. The trachea and oesophagus are divided, then reflected headwards, exposing the prevertebral muscles. The muscles are separated, and the ventral arch of the atlas and basilar part of the occipital bone exposed. The bone is removed to expose the membranes. These are incised to reveal the basilar artery lying on the pons. Blue dye is injected into one axillary artery. A diagram shows the anatomy of the area from the basilar artery to the heart. The diagram shows where the blue dye flows in the bloodstream. The bloodstream is shown. The action is repeated using the opposite artery. The intertitles describe what happens if the non-injected artery is occluded. Time start: 00:00:00:00 Time end: 00:06:23:22 Length: 00:06:23:22
