Basilar is an adjective relating to the base or foundation of something, often used in anatomy to describe basilar structures or membranes. It can also describe fundamental or base-level aspects in broader contexts. The term is technical and mostly found in scientific or medical discourse. It’s pronounced with emphasis on the second syllable and a clear initial /b/ followed by /eɪ/ or /eɪz/ depending on the speaker.

Bladder (noun) refers to the sac-like organ that stores urine in humans and many animals, or, more broadly, a blister-like sac in plants and in technical contexts. It is pronounced with a short, stressed initial syllable and a schwa-like second syllable in many accents. The term is common in medical, biological, and everyday discussion of bodily functions.

Bronchiectasis is a chronic condition characterized by permanent dilation and damage to the bronchi, leading to persistent cough and sputum production. It results from repeated infections or inflammatory processes that weaken airway walls, causing abnormal widening and mucus retention. Recognizing the term itself helps in medical communication and patient education in clinical settings.

Bulging is a noun referring to something that sticks out or swells outward, typically due to pressure or fullness. It conveys a visible, rounded prominence, such as a bulging eye or a bulging seam. The term often implies excess or noticeable protrusion beyond a normal contour.

Canal is a long, water-filled passage or duct that connects bodies of water or channels fluids within organisms. In geography, it refers to a constructed waterway for navigation, irrigation, or drainage. The term can also describe anatomical channels or conduits in plants or animals. It is commonly used in technical, architectural, or medical contexts as well as everyday descriptions of waterways.

Carcinoma is a malignant epithelial tumor that arises from the lining cells of organs or glands. It is one of the most common cancer types, capable of invading surrounding tissue and spreading to distant sites. The term distinguishes this cancer from sarcomas and other malignant neoplasms by its origin in epithelial tissue.

Carotid is a noun referring to the major arteries in the neck that supply blood to the brain, neck, and face. In medical contexts, it commonly denotes the common carotid artery or its branches. The term is used in anatomy, clinical discussion, and imaging reports to identify arterial pathways and assess blood flow or disease.

Cholecystectomy is a surgical procedure to remove the gallbladder. It is typically performed to treat gallstone-related pain or infection. The term combines Greek roots for bile, bladder, and surgical removal, and is used in medical contexts and formal discussions of gastroenterology.

Cholecystitis is an inflammation of the gallbladder, typically caused by gallstones or gallbladder irritation. It presents with right upper-quadrant abdominal pain, often fever and nausea, and may require medical evaluation or surgical treatment. The term combines Latin roots for bile and bladder, reflecting its anatomical origin. (2–4 sentences, ~60 words)

Cholelithiasis is a medical condition characterized by the presence of gallstones within the gallbladder or biliary tract, often causing biliary colic and potential complications. The term combines Greek roots referring to bile and stone and is used in clinical contexts as a formal diagnosis. It is a multisyllabic, Latinized medical noun encountered in radiology, gastroenterology, and general medicine notes.

Concha, as a noun, has multiple specialized meanings (anatomy: a shell-like structure; music: a term for a percussive shell or rhythmic sound; in Spanish, it can mean shell). In medical or anatomical contexts, it refers to a cavity or projecting part resembling a shell. In everyday Spanish, it’s a common noun for 'shell' and in some Latin American dialects, can appear in proper names. The term is used across disciplines with precise, context-driven pronunciation.

Coronal is an adjective used mainly in anatomy and dentistry to describe something relating to or near the crown orrim of a tooth or to the coronal plane in anatomy. It can also refer more broadly to structures that are crown-shaped or situated toward the crown. The term is primarily encountered in technical or clinical contexts and is formed from Latin corōn- “crown.”

Cyst is a noun for a closed sac-like structure within or on the body, often containing liquid or semi-solid material. It can be benign or, rarely, harmful. In medical contexts, it’s discussed for diagnosis, treatment, or surgical removal, and you might hear phrases like “ovarian cyst” or “sebaceous cyst.”

Diffusion is the process by which something spreads or dissuses through a medium or substance due to random motion and collisions of particles. It commonly refers to the spread of molecules, gases, or innovations in a system, driven by concentration differences or uniform distribution over time. In science, diffusion describes how compounds move from regions of higher to lower concentration, eventually reaching equilibrium.
