HISTOLOGICAL STRUCTURE OF TESTIS. Each testis is enclosed in a think connective tissue capsule . called the tunica albuginea,. inner to which is a vascular layer of loose connective tissue called the . The cortical domain of the anterior cerebral artery:. The central arteries:. The inside parts of the cerebrum are supplied by the central arteries which are arising from the component of the circle of Willis. The insult to these central arteries can lead to intracerebral hemorrhage.. Neuro surgery Arterial Venous Malformation (AVM) What is an AVM? An AVM is a tangle of blood vessels in the brain or on the brain surface which causes blood to bypass the network of capillaries and f Prof. . ahmed. . fathalla. & Dr. . jamila. . elmedany.
