The Brain Vascular System.

System. By Harry A. Kaplan and Donald H. Ford. Price, not given. Pp 230. Elsevier Publishing Co., Jan Van Galenstraat 335, Amsterdam, 1966. The purpose this monograph is to make the material discussed of use to as many individuals concerned with the problems the CNS as possible. To this end the authors discuss the embryology the brain vasculature ; the normal blood supply the brain, as well as its variations ; the meninges and spinal fluid; and the blood-brain barrier. The descriptions are richly supported by numerous illustrations injections and dissections the blood vessels in the human brain and by many useful diagrams. The description each blood vessel ends with a helpful diagram its constituent vessels. The nomenclature is that the Nomina Anatomica. After a detailed description the embryology the cerebral vessels, the authors find that the distribution the arteries in the newborn is comparable to the adult, the most common change being the relative dependence on the mesencephalic artery by the posterior cerebral artery as a major source blood for the posterior portion the cerebral hemisphere. Similarly, in the case the veins, the pattern in the adult closely resembles that seen at birth. The embryological section is purely descriptive, and such correlations as are possible with the adult vascular pattern are pointed out in the description individual blood vessels. Attention is called to the fact that, while the adult posterior cerebral artery is derived from vessels arising from the internal carotid artery, it receives blood from the vertebral-basilar system as well.
