Clinical Neuroanatomy: Spinal Cord and Brainstem Lesions
About this topic
This advanced neuroanatomy topic is designed for tertiary medical and clinical sciences students in Zambia, focusing on the clinical correlation of lesions in the spinal cord and brainstem. Students will learn to localize lesions based on physical findings, such as the Brown-Séquard syndrome, and understand the functional anatomy of ascending and descending tracts. The syllabus covers decussation patterns, the consequences of injuries at different levels, and the resulting sensorimotor deficits. Mastery of this complex spatial reasoning is fundamental for success in neurology rotations, surgical disciplines, and high-stakes professional examinations, where accurate lesion localization is a frequently tested skill that separates competent from excellent clinical diagnosticians.
What you'll practise (3 questions)
- Pain, sensory loss, and paresthesia in one leg suggest a spinal cord lesion.
- The dermatome rule is used clinically by physicians to determine level of pain perception, to explain referred pain, to discern the slow pain response, to determine the extent of cutaneous tissue damage. Which is correct?
- What are the results of unilateral damage to the contralateral in mass
