A life-size, realistic 4 parts model provides a through understanding of the structure and path of blood vessels in human brain. The model is sagittally sectioned, with both halves separable into four parts: the frontal with parietal lobes, temporal with occipital lobes, brain stem, and cerebellum. The basilar artery is also removable. The model rests on a cradle base and can be removed for closer examination. All parts are numbered and identified on the accompanying key-card.
