  3. Basic conception afferent information (nerves, axons, tracts) CNS efferent information (nerves, axons, tracts) ascending information (tracts) descending information (tracts)

  4. NERVE CELL = NEURON

  5. TYPES OF NEURONS

  6. DIVISION OF THE NERVOUS SYSTEM CNS PNS oligodendrocytes astrocytes Schwann cells and their derivatives sensors stimulus impulse effectors Striated skeletal muscles Non-striated muscles, myocardium, glands

  7. DIVISION OF THE PNS Cranial nerves I.- XII. • run through the skull base Spinal nerves – 31 pairs • run through foramina intervertebralia

  8. Glialcells of the CNS: astrocytes, oligodendrocytes, microglial, ependymal cells Glial cells of thePNS: myelinating andnon-nemyelinating Schwann cells, satellite glialcells, terminal glial cells

  9. unmyelinated axons (< 1m) myelinated axons

  10. FUNCTIONAL TYPES OF AXONS IN PNS somatosensory touch, proprioception, pain viscerosensory mechanoception, pain Afferent relay impulses for taste, hearing and balance sensory somatomotor striated muscles striated muscles branchiomotor Efferent non-striated muscles visceromotor sympathetic myocardium parasympathetic glands

  11. DIVISION OF THE CNS Brain (Encephalon) Spinal cord (Medulla spinalis) Brainstem (Truncus encephali) Medulla oblongata Pons Mesencephalon Cerebellum Diencephalon Telencephalon

  12. Neural crest

  13. sulcus limitans

  14. Primary subdivisions: prosencephalon, mesencephalon, rhombencephalon myelencephalon metencephalon mesencephalon diencephalon medulla spinalis telencephalon Secondary subdivision: telencephalon, diencephalon, mesencephalon, metencephalon, myelencephalon

  15. Conus medullaris Filum terminale Cauda equina

  16. Spinal segment Fila radicularia

  17. Intumescentia cervicalis C3 – T2 Intumescentia lumbalis T9 – T12

  18. Segment C5 Segment C1 Segment C5 Segment C8 Segment C8 Segment Th2 Segment Th2 Segment Th10 Segment L4 Segment L1 Segment S4 Segment L4 Segment S4

  19. SUBSTANTIA GRISEA – cornu anterius (columna anterior), cornu posterius (columna posterior), cornu laterale (columna lateralis), substantia intermedia, canalis centralis

  20. SUBSTANTIA ALBA – funiculus anterior, lateralis, posterior fissura mediana ant., sulcus medianus post., septum medianum posterius, sulcus anterolateralis, posterolateralis

  21. FUNCTIONAL ZONES IN THE NEURAL TUBE S SS VS cc VM SM BM

  22. Cornu posterius FR Substantia intermedia CC Cornu anterius

  23. Pseudounipol. neurons of the DRG Radix dorsalis Tr. dorsolateralis Lissaueri Ncl. posteromarginalis + Subst. gelatinosa Rolandi Fasc. gracilis Tr. spinobulbaris Fasc. cuneatus Ncl. proprius Ncl. thoracicus (Stilling-Clark.) Tr. spinocerebellaris post. Ncl. intermediomedialis Tr. spinocerebellaris ant. Tr. spino-thalamicus, -reticularis, -tectalis Tr. spino-olivaris Tr. olivo-spinalis

  24. Ncl. intermediolateralis Ncl.motorius

  25. Tr. corticospinalis lat. Tr. rubrospinalis Tr. reticulospinalis Tr. olivospinalis Tr. tectospinalis Tr. corticospinalis ant. Tr. vestibulospinalis
