USAHS Clinical Neuroscience Exam 2 2026 – 260 Questions and Answers on Stroke, Spinal Cord Lesions, Sensory Pathways and Multiple Sclerosis – University of St. Augustine for Health Sciences

This document contains 260 exam-style questions with detailed answers and illustrations designed to help students prepare for Clinical Neuroscience Exam 2 at the University of St. Augustine for Health Sciences (USAHS). The material provides a comprehensive review of neurological disorders, neuroanatomy, spinal cord pathways, cerebrovascular diseases, and neurophysiology concepts commonly tested in rehabilitation and neuroscience courses. The study guide begins with important neurological conditions such as intracerebral hemorrhage, ischemic stroke, embolic stroke, and lacunar infarcts, explaining how disruptions in cerebral blood supply can lead to neurological deficits. For example, the document defines an intracerebral hemorrhage as bleeding within the brain tissue due to trauma, while ischemic strokes occur when blood flow to brain tissue becomes blocked by a thrombus or embolus. Additional sections explain traumatic brain injury mechanisms, including coup and contrecoup injuries, concussion, intracranial pressure changes, and hydrocephalus. The guide also reviews important neurological signs such as Cushing’s triad (irregular respirations, widened pulse pressure, and bradycardia) that indicate increased intracranial pressure and potential brain herniation. The document also covers cerebrovascular anatomy and stroke syndromes, including the arterial supply of the brain through the anterior cerebral artery (ACA), middle cerebral artery (MCA), and posterior cerebral artery (PCA). It explains how different vascular territories affect neurological function, such as MCA strokes causing hemiparesis, aphasia, and visual field deficits, while PCA strokes can result in contralateral homonymous hemianopsia and visual disturbances. Another major section focuses on spinal cord anatomy and neurological lesion syndromes, including anterior cord syndrome, posterior cord syndrome, transverse cord lesions, and Brown-Séquard syndrome. The guide explains how damage to specific spinal cord tracts affects sensory and motor pathways, resulting in symptoms such as loss of vibration and proprioception, contralateral pain and temperature deficits, hemiplegia, or sacral sparing. The document also provides detailed explanations of major sensory and motor pathways, including: Posterior Column–Medial Lemniscus (PCML) pathway for fine touch, vibration, and proprioception Anterolateral (spinothalamic) pathway for pain and temperature sensation Spinocerebellar tracts for proprioceptive coordination Corticospinal tracts for voluntary motor control The guide explains where these pathways originate, where they decussate, and how they terminate in the primary somatosensory cortex, helping students understand lesion localization during neurological examinations. Additional topics covered include: Cranial nerve anatomy and neurological deficits Sensory receptors such as Meissner’s corpuscles, Pacinian corpuscles, Merkel receptors, and Ruffini endings Thalamic relay nuclei and somatosensory processing Blood–brain barrier physiology and cerebrospinal fluid circulation Brain meninges, venous sinuses, and intracranial hemorrhage types Brain herniation syndromes including uncal and tonsillar herniation Neurological disorders such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), and spinal muscular atrophy The document also discusses neurodegenerative diseases, including the pathophysiology of multiple sclerosis, the autoimmune destruction of myelin by immune cells such as CD8 T-cells, and clinical symptoms like optic neuritis, heat intolerance, and demyelinating plaques visible on MRI. It also reviews ALS mechanisms involving oxidative stress, protein misfolding, and degeneration of upper and lower motor neurons. This resource is particularly useful for students preparing for: USAHS Clinical Neuroscience Exam 2 Doctor of Physical Therapy (DPT) neuroscience courses Neuroanatomy and neurophysiology exams Neurological rehabilitation coursework Clinical neurology competency assessments It may be relevant for students enrolled in programs such as: Doctor of Physical Therapy (DPT) Occupational Therapy (OT) programs Neurological Rehabilitation programs Neuroscience and neurophysiology courses Allied Health and rehabilitation sciences programs The topics reviewed in this document align closely with foundational neuroscience textbooks such as “Neuroscience: Exploring the Brain” by Mark F. Bear, Barry W. Connors, and Michael A. Paradiso, which is widely used in neuroscience and health science education. Because the questions are presented in structured exam format with detailed explanations and illustrations, this document is ideal for comprehensive exam preparation, neurological concept reinforcement, and clinical neuroscience revision for rehabilitation and healthcare students.
