#apical

• Acrochroic — Regarding spores or mycological cellular structures; exhibiting intense pigmentation localized exclusively at the apex, tip, or terminal extremity, while the rest of the membrane remains translucent.
• Acrogenous — Regarding plants or structures; developing, growing, or originating exclusively at the tip, apex, or upper extremity, typical of vascular cryptogams like ferns.
• Acrogenesis — A physiological and structural process of formation, differentiation, or development of plant organs or tissues localized exclusively at the tip or upper extremity of an axis.
• Acrosincarpy — A structural condition or plant morphological anomaly characterized by the fusion, welding, or partial joining of individual carpels or fruits exclusively at their upper (apical) extremities, while the lower portions or bases remain distinct and separate during development.
• Acrospore — A type of asexual spore, conidium, or microscopic reproductive body that develops and separates exclusively at the upper extremity or apical zone of a specialized hyphal filament (conidiophore). This cellular structure, specific to lower fungi, is formed through terminal constriction or budding, ensuring highly efficient airborne dispersal of genetic material in the environment for species propagation.
• Acrotonous — Pertaining to acrotony; a plant, stem, or shrub characterized by the buds situated toward the apex (apical) developing much more strongly and rapidly than those at the base, structurally dominating branch growth. As a noun, the term describes a type of vegetative behavior where primary branching occurs exclusively within the upper zone of the central axis, representing an essential trait of many deciduous tree species.
• Acrotropism — A phenomenon of orientation, bending, or tropistic movement of plant organs (shoots, roots, stalks) directed strictly toward a point of prominence, a superior extremity, or an anatomical apex determined by an external stimulus (light, mechanical contact). This structural reaction guides the elongation direction of meristematic tissues, ensuring optimal spatial adaptation of the foliar or root apparatus in relation to surrounding environmental resources.
• Apicoectomy — A dental surgical procedure (also known as apicoectomy or root-end resection) consisting of the surgical removal of the apex (tip) of a tooth root, along with the surrounding necrotic or infected bone tissue. This surgical endodontic treatment is applied when classic root canal treatments fail, aiming to save the tooth from extraction.
• Apexian — Relating to the apex, pertaining to it, or located in the tip zone of a structure; derived from or positioned apically. The term is utilized restrictively in certain scientific translations or academic works as a rarer equivalent for the standard adjective 'apical'.
• Apical periodontitis — An acute or chronic inflammatory process localized at the level of the apex (tip) of a tooth root and the surrounding periapical tissues, usually caused by an untreated bacterial infection of the dental pulp (pulp necrosis). It manifests clinically through sharp pain during mastication or axial percussion.
• Apic — A rare, archaic form or simplified variant (sporadically found in literary translations or isolated technical treatises) of the standard adjective 'apical'; relating to the tip of a structure, pertaining to it, or articulated using the tip of the tongue in speech processing.
• Apical — Pertaining to the apex (tip), relating to it, or located at the terminal zone of a structure. In phonetics, it describes sounds (consonants) articulated by touching or bringing the tip of the tongue close to the teeth or alveoli; in botany, it refers to elements positioned at the tip of the stem or root (e.g., apical bud, apical meristem), and in medicine, it indicates localization at an organ's extremity.
• Apicoectomy — A dental surgical procedure consisting of the surgical removal of the apex (tip) of a tooth root, along with the surrounding infected or necrotic bone tissue. Widely known also as root-end resection or apicoectomy, it is applied when classic endodontic root canal treatment fails.
• Apicotomy — A surgical intervention consisting of the sectioning or incision of an apex (tip); in dentistry, it represents the surgical cutting of the root tip of a tooth to eliminate a persistent periapical infection, often used as a partial synonym for root-end resection. In an otorhinolaryngological context, it describes the surgical incision or drainage of the petrous apex of the temporal bone in severe cases of petrositis.
