This NSG 5003 Advanced Pathophysiology 2026/2027 study document provides a concentrated 12-page question-and-answer review of essential cellular and general pathophysiology concepts taught in NSG 5003 at South University. The material covers cell structure and function, cellular communication, membrane physiology, energy metabolism, cellular adaptation and injury, fluid compartments, electrolyte regulation, acid-base balance, and aging-related cellular changes. Its concise definition-and-answer format makes it suitable for rapid exam revision, reinforcement of terminology, and review of mechanisms underlying disease processes.
The first section establishes the foundations of cellular biology and physiology by reviewing differentiation, specialized cellular functions, eukaryotic cells, the nucleus, plasma membrane, cytoplasm, intracellular organelles, cellular receptors, and ligands. Students review the eight specialized cellular functions identified in the document—movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction, and communication—alongside mechanisms that hold cells together, including extracellular structures, cell-adhesion molecules, and specialized junctions.
Another major area is cell communication, signaling, and energy production. The material explains reception, transduction, cellular response, first and second messengers, receptor-mediated signaling, and relay chains responsible for transferring, amplifying, and distributing signals. It also covers adenosine triphosphate (ATP), oxidative phosphorylation, mitochondria, resting membrane potential, and action potentials, connecting cellular signaling with energy metabolism and membrane electrophysiology.
The document provides extensive exam review of cellular adaptation and cellular injury. Key adaptive processes include atrophy, hypertrophy, hyperplasia, dysplasia, and metaplasia, while injury mechanisms include free-radical formation, hypoxia and anoxia, ATP depletion, intracellular calcium accumulation, inflammation, immune activation, genetic abnormalities, nutritional deficiencies, and harmful physical agents. Students also review necrosis, apoptosis, hydropic swelling, lipid peroxidation, protein alterations, DNA damage, fever, leukocytosis, increased heart rate, pain, and elevated plasma enzymes as mechanisms or manifestations associated with cellular injury.
Important cellular structures and junctions receive additional attention, including mitochondria, Golgi complex, nucleolus, histones, desmosomes, tight junctions, gap junctions, and zona occludens. The study material links these structures to ATP production, protein packaging, ribosome formation, chromosome organization, cell adhesion, diffusion barriers, and communication between adjacent cells. This provides students with a useful bridge between normal cellular physiology and the mechanisms that become disrupted in disease.
The fluid and membrane-transport section reviews diffusion, osmosis, filtration, hydrostatic pressure, intracellular fluid (ICF), extracellular fluid (ECF), isotonic solutions, hypertonic solutions, hypotonic solutions, water balance, thirst, and antidiuretic hormone (ADH). Metabolic concepts such as catabolism, anabolism, substrates, amphipathic molecules, and protein functions are also included, reinforcing the biochemical and physiological foundations needed to understand altered cellular function.
Students also receive targeted review of major electrolytes and acid-base regulation, including potassium, calcium, phosphate, magnesium, hydrogen ions, buffers, acidosis, and alkalosis. The material connects potassium with intracellular osmolality and resting membrane potential, calcium with bone structure, clotting and receptor function, phosphate with buffering and energy, and parathyroid hormone, vitamin D, and calcitonin with calcium and phosphate regulation. Acid-base content addresses hydrogen-ion concentration, buffering systems, and respiratory and metabolic forms of acidosis.
The final section examines adaptive cellular responses and aging, including cellular responses to environmental injury, age-related physiological changes that can influence drug responses, somatic death, accumulated DNA damage, reduced proliferative capacity of stem cells, and accumulated metabolic damage. Overall, the document provides a compact foundation for understanding how changes at cellular and biochemical levels contribute to altered physiological function and disease.

NSG 5003 Advanced
Pathophysiology (South
University) 2026/2027 Expert
Verifed Ace the Test
Differentiation - ANSWER ✔✔(maturation) process in which cells
become specialized in structure and function
The eight specialized cellular functions are - ANSWER
✔✔movement, conductivity, metabolic absorption, secretion, excretion,
respiration, reproduction, communication
Eukaryotic cells - ANSWER ✔✔Contain a nucleus and other
organelles that are bound by membranes.
, The eukaryotic cell consists of three general components - ANSWER
✔✔plasma membrane, cytoplasm, and intracellular organelles
Nucleus - ANSWER ✔✔A part of the cell containing DNA and RNA
and responsible for growth and reproduction
Vaults - ANSWER ✔✔cytoplasmic organelles that are carrying
messengers of ribonucleic acid (mRNA) from the nucleus to the
ribosomal sites of protein synthesis
plasma membrane (cell membrane) - ANSWER ✔✔It's function is to
protect the cell and control what goes in and out. It is not a solid
structure. It is made of millions of smaller molecules so it is flexible and
porous (allows things to pass through it).
cellular receptors - ANSWER ✔✔protein molecules on the plasma
membrane, in the cytoplasm, or in the nucleus that can recognize and
bind with specific smaller molecules called ligands
Ligands - ANSWER ✔✔A molecule that binds specifically to a
receptor site of another molecule.
Cells are held together by three different means: - ANSWER ✔✔(1)
the extracellular membrane, (2) cell adhesion molecules in the cell's
plasma membrane, and (3) specialized cell junctions.
