APHY 101 Final Exam Study Guide 2026/2027 | 300+ Questions & Answers | Anatomy, Physiology, Skeletal, Muscular, Nervous System, Cells & Tissues | Ivy Tech Community College

This comprehensive APHY 101 Final Exam Study Guide 2026/2027 contains 300+ questions and answers across 51 pages for students reviewing foundational Anatomy and Physiology material at Ivy Tech Community College. The study material covers skeletal anatomy, bone development and repair, joints and body movements, muscular anatomy and contraction, the central and peripheral nervous systems, neurons and action potentials, brain anatomy, sensory receptors, special senses, cells and tissues, chemistry, metabolism, DNA and RNA, cellular transport, mitosis and the integumentary system. The document is structured as a detailed question-and-answer review for final-exam preparation. The skeletal system section begins with long-bone anatomy, including the epiphysis, diaphysis, medullary cavity, periosteum, compact bone and spongy bone. Students review ossification, the epiphyseal plate, osteoblasts and osteoclasts, as well as the major functions of the skeletal system: support, protection, movement, mineral storage and blood-cell formation. The guide also differentiates the axial and appendicular skeletons and explains the stages of fracture repair, including hematoma formation, fibrocartilaginous callus formation, bony callus formation and remodeling. The material then moves into joints and anatomical movements. Students review articular cartilage, joint capsules, ligaments, synovial membranes, synovial fluid, menisci and bursae before studying the six major types of synovial joints. Movement terminology includes flexion, extension, hyperextension, dorsiflexion, plantar flexion, abduction, adduction, rotation, circumduction, supination, pronation, inversion, eversion, protraction, retraction, elevation and depression. The muscular system section covers fascia, tendons, aponeuroses, muscle fibers, myofibrils, actin, myosin, the sarcolemma, sarcomeres, sarcoplasmic reticulum and transverse tubules. The study guide explains the neuromuscular junction and the role of acetylcholine in skeletal-muscle activation, followed by the sliding interactions between actin and myosin and the importance of ATP in muscle contraction. Aerobic and anaerobic ATP production are also reviewed, along with muscle origin and insertion, prime movers, synergists and antagonists. A major portion addresses the nervous system and neurophysiology. Students distinguish the central nervous system from the peripheral nervous system and compare somatic and autonomic divisions. Neuron structure, sensory neurons, interneurons, motor neurons and neuroglia are covered before the guide progresses to resting membrane potential, sodium and potassium ions, polarization, depolarization, repolarization and action potentials. Saltatory conduction through the nodes of Ranvier and neurotransmitter transmission across synapses are also important review topics. The brain and spinal cord material examines the meninges, cerebrospinal-fluid-filled ventricles, spinal reflexes and ascending and descending spinal tracts. Students review the frontal, parietal, temporal, occipital and insular lobes and their major functions, as well as the basal ganglia, thalamus, hypothalamus and diencephalon. The midbrain, pons, medulla oblongata and cerebellum are differentiated, while autonomic nervous-system questions contrast sympathetic fight-or-flight activity with parasympathetic energy-conserving functions. The guide provides detailed review of sensory physiology and special senses. Mechanoreceptors, thermoreceptors, nociceptors, chemoreceptors, proprioceptors, baroreceptors, stretch receptors, Meissner's corpuscles and Pacinian corpuscles are included. Students also study olfaction and the major taste sensations before reviewing the outer, middle and inner ear, cochlear hair cells, hearing, static equilibrium and dynamic equilibrium. Eye anatomy includes the retina, cornea, iris, lens, sclera and choroid, together with the functions of rods and cones in vision. The introductory anatomy and physiology portion distinguishes anatomy as the study of body structure from physiology as the study of function. Levels of organization progress from atoms and molecules through macromolecules, organelles, cells, tissues, organs, organ systems and the complete organism. Students also review the characteristics and requirements of life, homeostasis, receptors, control centers and effectors, followed by negative and positive feedback mechanisms. The basic chemistry and biochemistry section reviews atomic structure, protons, neutrons and electrons, followed by covalent, ionic and hydrogen bonding. Chemical reactions include synthesis, decomposition, exchange and reversible reactions, while students also review reactants, products, catalysts, acids, bases, electrolytes and the pH scale. Organic chemistry topics include carbohydrates, lipids, proteins, nucleic acids, triglycerides, phospholipids, steroids and amino acids, together with dehydration synthesis and hydrolysis. The cell biology material covers the plasma membrane, nucleus, cytoplasm, ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles, mitochondria, lysosomes, peroxisomes, cilia, flagella, nuclear pores, nucleolus and chromatin. Students then review membrane transport through diffusion, osmosis, facilitated diffusion, filtration, active transport, endocytosis, exocytosis and transcytosis, including the effects of hypertonic and hypotonic solutions on cells. Cell reproduction and metabolism are addressed through interphase, mitosis and cytokinesis, including prophase, metaphase, anaphase and telophase. The guide differentiates catabolism from anabolism and examines enzymes, active sites and denaturation. ATP production and utilization are connected with glycolysis, aerobic cellular respiration, the Krebs cycle and electron transport chain, helping students integrate cellular chemistry with physiological energy requirements. The genetics and protein-synthesis material compares DNA and RNA structures, nucleotides and nitrogenous bases. Students review DNA replication, transcription, translation, mRNA codons, tRNA anticodons and mutations. These questions reinforce the relationship between genetic information and protein synthesis and provide foundational molecular biology review within the broader APHY 101 curriculum. The final sections focus heavily on histology and the integumentary system. The four primary tissue categories—epithelial, connective, muscle and nervous tissue—are reviewed alongside epithelial classification and glandular epithelium. Connective-tissue topics include fibroblasts, macrophages, mast cells, collagen, elastic and reticular fibers, extracellular matrix, areolar and adipose tissue, dense regular and irregular connective tissue, cartilage, bone and blood. Skeletal, cardiac and smooth muscle are also differentiated. For the integumentary system, students review the epidermis, dermis and subcutaneous layer, including the five epidermal strata from stratum basale through stratum corneum. The guide covers the papillary and reticular layers of the dermis, arrector pili muscles, sebaceous glands, eccrine and apocrine sweat glands, hypothermia, hyperthermia and pigments contributing to skin coloration. This gives students a broad final-exam review spanning cellular organization through major organ-system physiology. For academic cross-reference, the subjects covered are consistent with standard undergraduate Anatomy and Physiology references such as OpenStax Anatomy and Physiology 2e and widely used A&P textbooks such as Hole's Essentials of Human Anatomy & Physiology. These references provide established coverage of cellular biology, tissues, skeletal and muscular anatomy, neural physiology and the special senses. The uploaded study guide itself does not provide a formal textbook or journal bibliography, so a particular book should not be presented as the source of its questions. Students should also compare individual answers with their current APHY 101 syllabus, assigned textbook and instructor materials, especially where the guide uses simplified terminology. Relevant students: This study guide is most relevant to Ivy Tech Community College students enrolled in APHY 101 (Anatomy and Physiology I) and learners preparing for an APHY 101 final or comprehensive examination. It is particularly useful for nursing prerequisites, allied-health, medical assisting, healthcare and pre-professional students who need intensive question-and-answer review of bones and joints, muscles, nervous-system physiology, sensory organs, chemistry, cells, metabolism, genetics, tissues and skin.
