    Study Notes

    Neuroanatomy for Physiotherapists

    • This book is on neuroanatomy specifically for physiotherapy students.
    • It was written by Professors Mohamed Bakry, Hafiz Waly, Saber Shona, and Hassan Heidar of the Anatomy Department, Faculty of Medicine, Cairo University.
    • The book includes staff member lists and a table of contents.
    • The book covers several topics including the introduction of the nervous system, spinal cord, cerebral meninges, cerebrospinal fluid, brain stem, medulla, pons, midbrain, fourth ventricle, cerebellum, interpeduncular fossa, cerebral hemisphere, functional areas of the cerebral hemisphere, internal structure of the cerebral hemisphere, white matter of the cerebral hemisphere, basal ganglia, the internal capsule, diencephalon, blood supply of the brain, spinal nerves, spinal cord coverings, blood supply of the spinal cord, the cerebral meninges, and the cavities of the CNS.
    • The text further describes the brain, including the medulla oblongata, pons, and midbrain. It details the spinal cord, its external features, segments, and coverings. Specific sections detail the blood supply to both the brain and spinal cord.
