  3. Main nerve tracts in the spinal cord B A C D G E F

  4. Posterior white columns Lateral corticospinal tract Anterior & posterior spinocerebellar tracts Anterior & posterior spinothalamic tracts Olivospinal, vestibulospinal, tectospinal tracts Anterior corticospinal tract Rubrospinal tract

  5. Closed medulla at the level of decussation of pyramids Fasciculus gracilis Spinal tract of trigeminal nerve Nucleus gracilis Fasciculus cuneatus Nucleus cuneatus Spinal nucleus of trigeminal nerve Spinal root of the accessory nerve Posterior spinocerebellar tract Central canal Spinothalamic tract Medial longitudinal fasciculus Anterior spinocerebellar tract Decussation of pyramids Pyramid

  6. Fasciculus gracilis Spinal tract of trigeminal nerve Nucleus gracilis Fasciculus cuneatus Nucleus cuneatus Spinal nucleus of trigeminal nerve Central canal Medial longitudinal fasciculus Posterior spinocerebellar tract Spinal root of the accessory nerve Spinothalamic tract Decussation of medial lemnisci Anterior spinocerebellar tract Pyramid Hypoglossal nerve Closed medulla at the level of decussation of medial lemnisci

  7. Medulla Oblongata at the level of middle of the olivary nuclei Inferior medullary velum Cavity of 4th ventricle Medial longitudinal fasciculus Spinal tract & nucleus of trigeminal nerve Vestibular & cochlear nuclei Inferior cerebellar peduncle Vagus nerve Anterior spinocerebellar tract Reticular formation Spinothalamic tract Olivary nucleus Tectospinal tract Olive Hypoglossal nerve Medial lemniscus Pyramid

  8. Pons at the level of facial colliculus Superior medullary velum Cavity of 4th ventricle Medial longitudinal fasciculus Superior cerebellar peduncle Facial colliculus Reticular formation Vestibular nuclei Inferior cerebellar peduncle Spinal lemniscus Spinal tract & nucleus of trigeminal nerve Medial lemniscus Transverse pontine fibres Facial nerve Abducent nerve Corticospinal & corticonuclear fibres Pontine nuclei
