The term denotes a vascular disorder at the microvascular level.

Microbiology is the branch of biology that studies microscopic life forms, including bacteria, viruses, fungi, and protozoa. It covers the biology of microbes, their roles in health, disease, and ecological systems, and the methods used to culture, observe, and analyze them. It combines chemistry, physics, and genetics to understand how microorganisms function and interact with their environments.

Myringoplasty is a surgical procedure to repair a perforated eardrum using graft material. The term combines ‘myringo-’ (related to the eardrum) and ‘-plasty’ (surgical repair). It is typically performed to restore hearing and prevent recurrent infections, often following trauma or chronic otitis media.

Nephrectomy is a surgical procedure to remove a kidney, typically performed for disease, cancer, or donation. It involves precise dissection and hemostasis, and may be done via open or laparoscopic approaches. The term encompasses the action and instrument- or procedure-based context in medical settings.

Nephrology is a medical specialty focused on the kidneys, including their structure, function, diseases, and treatment. It involves diagnosis, management, and research related to kidney conditions, dialysis, and transplant considerations. The term combines Greek roots for kidney and study, reflecting its precise clinical scope and scholarly basis.

nephrotoxic is an adjective describing substances that can damage the kidneys; used in medical contexts to denote agents, drugs, or toxins harmful to renal tissue. It denotes potential or actual kidney injury risk and is commonly found in pharmacology and toxicology literature. The term combines Greek roots for kidney and poison, reflecting its specific organ-otoxic meaning.

Neurapraxia is a mild nerve injury characterized by a temporary blockage of nerve conduction without axonal disruption. Recovery is typically complete, often within days to weeks, as myelin integrity is preserved and the nerve conduction block resolves. It differs from more severe nerve injuries by its favorable prognosis and lack of Wallerian degeneration.

Neuroblastoma is a malignant tumor that arises from immature nerve cells, typically in the adrenal glands or along the spinal cord. It most often affects children, and its name reflects its origin from neuroblasts. The term combines neuro-, blast-, and -oma, signaling neural tissue origin and tumor formation. (2–4 sentences, 50–80 words)

neurodegenerative is an adjective describing a disease process characterized by progressive loss of structure or function of neurons, typically involving degeneration of the nervous system. It is used in medical and research contexts to describe conditions such as Alzheimer's or Parkinson's disease, where neurons progressively deteriorate. The term combines neuro- (nerve) with degenerative (degenerating) to indicate ongoing neuronal decline.

Neuropathology is the medical specialty that studies diseases of the nervous system tissue, including brain and nerve disorders, through laboratory and autopsy findings. It combines neurology with pathology to diagnose, characterize disease processes, and understand mechanisms at cellular and molecular levels. This field informs prognosis and research into neurological conditions.

Neuropsychology is the branch of psychology that studies how the brain’s structure and function influence behavior and cognitive processes. It integrates neurology and psychology to understand disorders, cognition, emotion, and how brain injuries affect thinking. Professionals in this field assess, diagnose, and research brain–behavior relationships using psycho- and neurobiological methods.

A protein that is bound to, and forms a complex with, nucleic acids (DNA or RNA). In cells and viruses, nucleoprotein refers to the protein component that packages, protects, or regulates nucleic acids, often influencing replication and transcription. It is a technical term used in molecular biology and virology to describe protein-nucleic acid assemblies.

Osseointegration is the process by which living bone fuses to a titanium implant or prosthetic, creating a stable, integrated support. It involves bone remodeling around the implant surface, allowing load transfer and lasting anchorage. In biomedical contexts, it's essential for dental implants, orthopedic devices, and craniofacial prosthetics, enabling durable, functional connections between bone and materials.

A medical specialty focusing on the medical and surgical care of the ear, nose, and throat, and related areas of the head and neck. Practitioners—otolaryngologists—diagnose and treat disorders of these structures, including hearing, speech, balance, and airway issues. The term combines ancient Greek roots for ear (oto-), larynx (laryngo-), and study/knowledge (-logy).

Pharmacodynamics is the branch of pharmacology that studies the biochemical and physiological effects of drugs on the body, including mechanism of action and the relationship between drug concentration and effect. It explains how drugs exert therapeutic or adverse effects, and how factors like receptor binding, signal transduction, and dose influence outcomes. This field complements pharmacokinetics by focusing on what the drug does to the body.

Pharmacokinetics is the branch of pharmacology that studies how a drug is absorbed, distributed, metabolized, and eliminated by the body over time. It describes the time course of drug concentrations in plasma and tissues, guiding dosing and therapeutic monitoring. In essence, it links a drug’s chemical properties to its physiological fate and clinical effects.

Photomicrography is the practice or process of creating photographs under a microscope, typically to document microscopic specimens.
