BIO 252 – Lab 1 Nervous System Foundations (65 Questions) | Neuron Anatomy, Spinal Cord & Synapses – 2025

This expert-verified document presents 65 essential lab questions and answers from BIO 252 – Human Anatomy & Physiology II, focused on Lab 1: Nervous System Anatomy. It is tailored for students preparing for early-semester lab practicals or model identification exams on neurons, spinal cord anatomy, and basic neuroanatomical structures. The first section emphasizes the structure and function of neurons, covering: Cellular organelles and their roles: nucleus, nissl bodies, smooth ER, mitochondria, Golgi apparatus Neural components: dendrites, axon hillock, axon, nodes of Ranvier, myelin sheath, axon terminal Synaptic connections: axodendritic, axosomatic synapses The second section focuses on the spinal cord and central nervous system, including: Gross anatomical landmarks: cervical and lumbar enlargements, medullary cone, cauda equina Protective layers: dura mater, arachnoid mater, pia mater Neuronal pathways and regions: anterior/posterior/lateral horns, columns, commissures, roots, ganglia, rami Associated blood supply: anterior/posterior spinal arteries and veins This document is ideal for students in: Anatomy & Physiology II, Neuroscience, Nursing, Pre-Med, or Health Science programs Courses that involve nervous system lab work, neuroanatomy, or spinal cord dissection/model identification Exam prep needing quick-reference, accurate structure-to-function matching Perfectly structured for lab quizzes, oral exams, or review before practicals, this resource strengthens foundational knowledge of nervous system anatomy and cellular neuroscience.
