SPINAL CORD

Objectives

  • Describe the gross anatomy of the spinal cord and its relationship to the vertebral canal and the organization of blood supply to the spinal cord.
  • Identify the locations of the corticospinal tract, the posterior column-medial lemniscus system and the anterolateral system in a cross section of the spinal cord.
  • Identify the location of somatic sensory, visceral sensory, somatic motor and visceral motor neurons in the gray matter of the spinal cord.
  • Sketch the longitudinal course of the corticospinal tract, the posterior column-medial lemniscus system and the anterolateral system throughout the spinal cord and brainstem and demonstrate an understanding of somatotopic arrangement, site of crossing fibres, and modalities carried within these tracts.
  • Identify the meningeal layers around the spinal cord and relate these to the spaces they border with and define. Explain the functional importance of these spaces for clinical practice.
  • Describe how the neuroanatomy of micturition relates to the underlying pathways and their locations in the brainstem and spinal cord. Correlate clinical presentations of bladder dysfunction to lesions of these pathways.
  • Describe the typical symptoms seen in spinal cord injuries as they relate to motor, sensory and autonomic function to the underlying anatomy.
