PNB 2274 FINAL EXAM QUESTIONS AND CORRECT ANSWERS ALL GRADED A+

Stop stressing over the PNB 2274 final. This comprehensive 49-page digital question bank contains every major topic from the entire semester, organized with correct answers and detailed explanations. Designed to mirror exam difficulty, this resource turns complex physiology and anatomy concepts into easy-to-remember Q&A pairs. What's Inside (Complete Semester Coverage): Section 1: Foundations of Anatomy & Physiology Anatomy vs. physiology (structure vs. function) Anatomical position, directional terms (superior/inferior, proximal/distal, medial/lateral) Body planes (coronal, transverse, midsagittal) Homeostasis & control systems (negative vs. positive feedback) Section 2: Membrane Transport & Cell Biology Passive transport (simple diffusion, osmosis, facilitated diffusion, bulk filtration) Active transport (primary vs. secondary, Na+/K+ pump) Fick's law of diffusion Channels, carriers, and pumps Section 3: Tissue Biology 4 major tissue types: epithelial, connective, muscle, nervous Epithelial characteristics (cellularity, polarity, attachment, avascular, regeneration) Gland types: merocrine, apocrine, holocrine Cell junctions: tight, adhering, desmosomes, gap Connective tissue: loose (areolar, adipose, reticular) & dense (regular, irregular) Cartilage (hyaline, fibrocartilage, elastic) & bone (compact vs. cancellous) Section 4: Bone & Skeletal System Osteoblasts, osteoclasts, osteocytes Osteon (haversian system) structure Bone mechanics: stress-strain curves, yield point, toughness, stiffness, elasticity Axial vs. appendicular skeleton Joint types: fibrous, cartilaginous, synovial (plane, hinge, pivot, condylar, saddle, ball-and-socket) Section 5: Nervous System CNS vs. PNS, brain protection (meninges, BBB, CSF) Cerebrum lobes (frontal, parietal, occipital, temporal) & functions Broca's area, Wernicke's area, arcuate fasciculus Basal nuclei, diencephalon (thalamus, hypothalamus, epithalamus) Limbic system (amygdala, hippocampus) Brainstem (midbrain, pons, medulla) & cerebellum Memory types (explicit vs. implicit, short-term vs. long-term) Cranial nerves I-XII (functions: sensory, motor, or both) Ascending & descending tracts Sensory receptors (thermoreceptors, mechanoreceptors, chemoreceptors, photoreceptors, nociceptors) Pain pathways: gate control theory, neospinothalamic tract Vision: cornea, iris, lens, retina, rods vs. cones, phototransduction Section 6: Neurophysiology & Membrane Potentials Resting membrane potential (Nernst equation, Goldman-Hodgkin-Katz) Depolarization, hyperpolarization, repolarization Action potentials vs. graded potentials Temporal vs. spatial summation Synaptic transmission (voltage-gated Ca²⁺ channels, ligand-gated channels, GPCRs) Why This Guide Works: All correct answers provided – no guessing, no wasted time Clear Q&A format – perfect for active recall and self-testing Complete coverage – from basic anatomy to complex neurophysiology Memory aids included – the infamous "Does this class suck? – yes" opener (we feel you!) Perfect For: University of Connecticut (UConn) PNB 2274 students Pre-med, nursing, PA, PT, and health science majors Anyone needing to master anatomy & physiology for a cumulative final Format: Digital PDF (Instant Download) – 49 pages, ready for tablet annotation or printing
