OMK2 Exam Q&A (80+) | Neuro1 Gross Anatomy, Brainstem, Lobes, Ventricles, Nerves | 2025/2026 | CNS Structural ID & Imaging

This document presents 80+ clearly answered and verified exam questions for the OMK2: Neuro1 (Gross Anatomy) module, tailored for the 2025/2026 academic year at [University Name]. It provides a complete overview of labeled structures in gross neuroanatomy, essential for mastering structural identification across the spinal cord, brainstem, cerebellum, cerebral lobes, ventricular system, and cranial nerves. All answers are paired with neuroanatomical terms and functional correlates to support recognition in prosection, models, and imaging-based exams. Structures are grouped by region to mirror how material is taught and tested. Key topics include: Peripheral Nerve Anatomy: Axon layers (endoneurium, perineurium, epineurium), dorsal/ventral roots, vasa nervorum, nerve fascicles Meninges & Spaces: Dura (falx cerebri, tentorium cerebelli), arachnoid and subarachnoid contents (CSF, hemorrhage sites), pia mater (e.g., denticulate ligaments) Spinal Cord & Root Anatomy: Cervical/lumbosacral enlargements, conus medullaris, cauda equina, filum terminale Brainstem Structures: Pyramids, olives, cranial nerve exits, middle/superior/inferior cerebellar peduncles Cerebellum & Midbrain: Vermis, tonsils, colliculi, cerebral peduncles Cerebrum: Frontal, temporal, occipital lobes (gyri & sulci), cingulate gyrus, uncus, corpus callosum components, parahippocampal gyrus Ventricular System: Lateral ventricles (anterior horn, trigone, etc.), 3rd and 4th ventricles, cerebral aqueduct, foramen of Monro Arterial Supply: ACA, MCA, PCA, vertebral, basilar, PICA, superior cerebellar artery Cranial Nerves I–XII: Locations from bulb to brainstem (olfactory, optic, oculomotor, trigeminal, etc.) Who this document is for: Medical students in neuroanatomy, radiology, or OSPE/OSCE preparation Students in neuroscience, nursing, or physiotherapy needing spatial CNS structure familiarity Candidates for NBME, STEP 1, COMLEX, or lab practicals with high visual/anatomical ID demand Learners seeking clear, categorized ID lists for pre-clinical gross anatomy modules All terms are sorted logically and aligned with class LOs and brain region labeling, making it ideal for checklist-based review and structure recall.
