#body

• Anteroposterior — Extending, oriented, or measured from the front (anterior) to the back (posterior) of the body or an organ; relating to the axis that traverses the organism perpendicular to the frontal plane. In medical imaging, it defines the standard incidence of X-rays penetrating the anterior wall.
• Anti-antibody — A specific antibody produced by the immune system that recognizes and binds directly to another antibody molecule (immunoglobulin); an anti-idiotypic antibody. In immunology, they are key to regulating immune responses and are widely used in diagnostic laboratory assays.
• Anti-cellulite — Combating, reducing, smoothing, or preventing cellulite (the uneven accumulation of adipose tissue and toxins under the skin, resulting in an orange-peel appearance); a cosmetic product (cream, oil, gel), therapeutic treatment (massage, lymphatic drainage), or technical device structurally designed to stimulate microcirculation, improve skin elasticity, and promote lipolysis.
• Antibody — A complex protein molecule (immunoglobulin) synthesized by B lymphocytes of the immune system in response to the entry of a foreign substance (antigen) into the body, possessing the specific structural capacity to bind to it for neutralization or destruction. This biological barrier forms the foundation of acquired immunity, ensuring defense against bacteria, viruses, and toxins.
• Antigen — Any macromolecular substance (protein, polysaccharide, or toxin), usually foreign to the body, capable of triggering a specific immune response, stimulating antibody synthesis, and reacting specifically with them. As an adjective, it describes an element possessing this immunogenic property.
• Antigenic — Relating to antigens or possessing the property to act as an antigen; characterized by the capacity to stimulate a specific immune response. In modern virology, it describes viral genetic mutations (such as antigenic drift or shift) allowing pathogens to evade host antibodies.
• Antiglobulin — A specific antibody (immunoglobulin) obtained by immunizing an animal, capable of recognizing and binding to other human globulins (antibodies) present in serum or fixed on cell surfaces; utilized as an essential immunological reagent in laboratory diagnostics (such as the Coombs test).
• Anti-insulin — A biological substance, specific antibody, or hormone (such as glucagon or cortisol) possessing a physiological action antagonistic to insulin, blocking or diminishing its blood glucose-lowering effect. In a structural sense, it causes an increase in blood sugar levels and can contribute to the development of insulin resistance.
• Antipepsin — An antibody, specific antibody, or biological substance with an inhibitory role that neutralizes the enzymatic activity of pepsin to digest proteins. This structural factor protects the gastric mucosa from self-digestion and is used in clinical research to study homeostatic mechanisms within the stomach.
• Antipyretic — Reducing, combating, or normalizing elevated body temperature in case of fever; a drug or therapeutic agent structurally designed to act on the thermoregulatory center in the hypothalamus, decreasing heat production and stimulating its dissipation through sweating and peripheral vasodilation. This precision medication relieves thermal discomfort without affecting normal body temperature.
• Antirenin — A specific antibody that neutralizes renin (an enzyme secreted by the kidneys with a major role in regulating blood pressure through the renin-angiotensin-aldosterone system). In biomedical research and pharmacology, the substance is used as an experimental or immunological tool to block excessive renin enzymatic activity, helping to study the mechanisms of renal hypertension.
• Antitoxin — A specific antibody formed in the body of a human or animal as an immune response to the introduction of a bacterial, plant, or animal toxin, having the capacity to selectively neutralize its toxic effect. In medical practice, the term also designates the injectable pharmaceutical preparation obtained from the serum of immunized animals, used as an emergency treatment in serious infectious diseases such as diphtheria, tetanus, or botulism.
• Anthropometric — Pertaining to anthropometry or to the measurement of the dimensions and proportions of the human body; specific to techniques for the quantitative determination of height, weight, bone circumferences, and skinfold thickness. In sports medicine, ergonomics, and forensic anthropology, these structural data are essential for assessing physical development, designing industrial objects, or identifying individuals.
• Anthropometry — A scientific method and branch of physical anthropology dealing with the systematic measurement of the dimensions, proportions, weight, and body composition of the human organism. Data obtained through anthropometry are used to study the biological variability of populations, monitor nutritional status, optimize athletic performance, and design ergonomic furniture or equipment.
• Anthropometer — A precision medical and anthropological instrument used to measure human body height, the length of anatomical segments (trunk, limbs), or large bone diameters. This calibrated device, structurally consisting of a vertical graduated metal rod equipped with a movable slider and rigid transverse arms, ensures the collection of faithful anthropometric indices according to standardized protocols.
• Anthroposomatology — A specialized branch of physical anthropology dealing with the study of the structure, form, proportions, and variability of the human body in relation to evolutionary, hereditary, and environmental factors. This field analyzes the correlations between somatic parameters and various bio-physiological or ethnic aspects of populations, providing essential data for understanding the morphological variability of the human species.
• Anthropotomy — A branch of anatomy specifically concerned with the dissection and study of the internal structure of the human body. This fundamental field provides the macroscopic structural and topographic descriptions necessary for understanding organ localization, serving as the cornerstone of medical and surgical training for performing safe operative procedures.
• Tilt — A physical position, state, or shape of a body or object that exhibits an inclination, an oblique curvature, or a downward bend relative to an ideal vertical axis. In a popular or figurative sense, it can describe a permanent postural deformation or a minor slope of a structurally degraded ground.
• Arching — The act of bending into an arc and its result; a physical, mechanical, or biological process through which an elastic body, a material structure, or an anatomical line curves, bends, or alters its geometric flexibility under the action of an external force or internal tension. In design and art, it represents an aesthetic property conferring dynamism and harmony to outer shapes, while in engineering it defines the structural capacity of an assembly to absorb kinesthetic shocks through reversible deformations.
• Hydrometer — A measuring instrument consisting of a sealed glass tube, equipped at its lower part with a ballast bulb filled with shot or mercury and at its upper part with a thin graduated stem, used for the direct determination of a liquid's density or specific gravity. In a structural sense, its operation is based on variable vertical immersion in the fluid depending on its density, the level to which the stem sinks indicating the desired value on the scale.
