BIO 251 Final Exam 2026/2027 | 166 Questions & Answers | Anatomy, Physiology, Nervous System, Muscles & Special Senses

This BIO 251 Final Exam 2026/2027 study resource contains approximately 166 question-and-answer terms across 17 pages, providing a concentrated review of foundational human anatomy and physiology concepts. The material begins with essential concepts such as accommodation, acetylcholine, actin, action potentials and adipose tissue and progresses through cellular biology, tissues, bones, muscles, the nervous system, sensory physiology and endocrine regulation. The uploaded document identifies the course code as BIO 251 and the academic period as 2026/2027, but it does not name a university, so a university affiliation should not be invented for the listing. A substantial section focuses on cellular and molecular physiology, including ATP, amino acids, carbohydrates, lipids, proteins, nucleic acids, electrolytes, organelles, the plasma membrane and the fluid mosaic model. Membrane-transport mechanisms such as facilitated diffusion, endocytosis, exocytosis, phagocytosis and pinocytosis are included alongside osmotic concepts such as isotonic and hypertonic solutions and crenation. These concepts establish the cellular foundation needed to understand the more advanced physiological systems covered later in the document. The resource provides extensive coverage of the musculoskeletal system, including skeletal, smooth and cardiac muscle; actin and myosin; sarcomeres; Z discs; I bands; the sliding filament mechanism; power strokes; calcium ions; sarcoplasmic reticulum; motor end plates; and acetylcholine at the neuromuscular junction. Bone and connective-tissue concepts include osteoblasts, osteoclasts, osteocytes, periosteum, bone matrix, articular cartilage, ligaments, tendons and different bone classifications. The nervous system and neurophysiology material reviews neurons, neuroglia, Schwann cells, satellite cells, microglia, ependymal cells, myelin, neurotransmitters, synaptic vesicles and the synaptic cleft. It also covers depolarization and repolarization through voltage-gated sodium and potassium channels, action potentials and saltatory conduction. Central nervous system structures represented include the cerebrum, hypothalamus, medulla oblongata, meninges, dura mater, arachnoid mater and subarachnoid space. Another major emphasis is special senses and sensory anatomy. Eye-related concepts include the lens, iris, pupil, retina, rods, cones, fovea centralis, optic nerve, accommodation, visual acuity, myopia, hyperopia, presbyopia, cataracts and glaucoma. Ear and equilibrium material includes the auricle, tympanic membrane, ossicles, stapes, cochlea, cochlear duct, organ of Corti, hair cells, semicircular canals, utricle, otoliths and static and linear equilibrium. The scope closely overlaps with standard undergraduate anatomy and physiology curricula. A useful academic reference is Betts et al.'s Anatomy and Physiology 2e, which OpenStax identifies as a 2022 anatomy and physiology textbook and which provides coverage of the structural and physiological foundations represented throughout this study material. Relevant students: This document is most relevant to BIO 251 students, Anatomy and Physiology students, pre-nursing students, nursing students, pre-medical students, allied health students, biology majors, medical-assisting students and other health-science students reviewing anatomy and physiology terminology for a cumulative examination. Because the source itself does not identify a particular university, it is best marketed by the verified BIO 251 course code rather than attributing it to an unsupported institution.
