‫بسم هللا الرحمن الرحيم‬ OLS OMEr's LECTURES SERIES Clinical and applied anatomy neuroscience The nervous system Introductory session By Dr. omer abdelsalam mohammed musa 1 2024 DR.OMEr's PPT  By the end of this lecture you are expected to be able to: 1. Name the divisions of the nervous system. 2. Describe the lobes of the cerebrum. 3. Describe the white and gray matters of the cerebrum. 4. Discuss the functional Anatomy of Nervous system. 5. Correlate the function with common lesions. 6. Describe some methods of brain imaging. 2 DR.OMEr's PPT Central Peripheral (CNS) (PNS) Brain Spinal Cord Cerebrum Brain stem 3 Cerebellum DR.OMEr's PPT  Peripheral (PNS) Cranial Nerves Spinal nerves Others 4 DR.OMEr's PPT  Somatic Autonomic (ANS Sympathetic Parasympathetic 5 DR.OMEr's PPT Main parts Cerebrum a- Forebrain :- (cerebral hemispheres). b- Midbrain :- c- Hindbrain :- c1- Pons. c2- Medulla oblongata. c3- Cerebellum. d- spinal cord. Medulla Pons Midbrain Oblangata 6 DR.OMEr's PPT  Spinal Cord 7 DR.OMEr's PPT  EXT. Topographical anatomy (features) Central Sulcus Parietal Occipital Frontal Temporal Lateral Fissure Cerebellum 8 DR.OMEr's PPT 9 DR.OMEr's PPT 10 DR.OMEr's PPT Contains three major groups of axons: - Association tracts, - Commissural tracts, and - Projection tracts. 11 Ventricular DR.OMEr's PPT  - The cerebral nuclei are located within the central white matter in the cerebral hemispheres. - They include the caudate nucleus, amygdaloid body, putamen and globus pallidus, and claustrum. Lentiform 12 DR.OMEr's PPT 13 DR.OMEr's PPT 14 DR.OMEr's PPT  3) Pia mater 2) Arachnoid The spinal cord is (like brain) invested by three 1) Dura mater meningeal coverings. 1) Dura mater - "tough mother", strong. 2) Arachnoid mater - spidery looking, carries blood vessels, etc. - Subarachnoid space. 3) Pia mater. DR.OMEr's PPT  Functional Anatomy of the Nervous System 16 DR.OMEr's PPT  CORTICAL HIGH FUCTIONAL AREAS 17 DR.OMEr's PPT - The primary motor cortex in the frontal lobe directs voluntary movements. - A motor speech area is responsible for the motor functions involved in speaking. 18 DR.OMEr's PPT The primary somatosensory cortex in the parietal lobe collects somatic sensory information from various general sensory receptors. 19 DR.OMEr's PPT  CLINICAL AND APPLIED POINTS 20 DR.OMEr's PPT  Lumbar Puncture = (Spinal Tap) L3 L4 For clinical examination of CSF or administration of radiopaque dyes. DR.OMEr's PPT  Diagnostic procedures used to assess neurological condition and function range from routine reflex testing to sophisticated techniques such as cerebral angiography, CT scans, and MRI scans. 22 DR.OMEr's PPT  ANGIOGRAPHY; NORMAL VESSELS 23 DR.OMEr's PPT  0900108701 - CALL - TELEGRAM - W APP FEEL FREE YOU ARE WELCOME ANY TIME…. 24 DR.OMEr's PPT  ‫‪THANKS A LOT‬‬ ‫وبالتوفبق ‪...‬ربنا‬ ‫يحفظكم‬ ‫والحمد هلل رب العالمين‬ ‫‪25‬‬ ‫‪DR.OMEr's PPT‬‬
