Atony is a medical term for lack of muscle tone or general weakness in a body part, outside of normal muscle control. It can refer to a diminished ability to contract muscles or maintain a posture, or to a condition of decreased physiological tone in tissues. The term is used in clinical contexts and can appear in discussion of neuromuscular disorders and recovery scenarios.

Atrial is an adjective relating to the atrium of the heart, typically used to describe conditions, activities, or structures involving the atria. It can also describe anatomical regions associated with the heart’s upper chambers in medical contexts.

Auscultation is the medical act of listening to internal body sounds, typically with a stethoscope, to assess heart, lung, and vascular function. It is a skilled diagnostic technique that involves carefully identifying normal and abnormal sounds to inform clinical decisions. The term combines Greek roots for 'to listen' and 'to hear' and is used in formal medical contexts and examinations.

Autonomic describes the involuntary, automatic processes of the nervous system, such as heartbeat and digestion, that operate without conscious control. It is typically used in medical or physiological contexts to contrast with voluntary or somatic functions. The term often appears in discussions of the autonomic nervous system and its regulatory roles.

Axillary describes anything related to the armpit, especially the armpit region and its ducts or lymph nodes. In anatomy, it often refers to the axilla, the area beneath the shoulder where vessels and nerves pass. The term is used in clinical contexts and standard anatomical discourse, distinct from external features of the armpit itself.

Bacteremia is the presence of bacteria in the bloodstream. It is usually detected in clinical contexts and can indicate infection or be a precursor to septicemia. Pronounced with multiple syllables, the term emphasizes a medical-rooted origin and is used in formal, professional discourse.

Bilirubin is a yellow-orange pigment formed from the breakdown of heme, primarily from aged red blood cells. It circulates in the blood, is taken up by the liver, and excreted in bile. Clinically, bilirubin levels are used to assess liver function and red blood cell turnover. The term spans medical, biochemical, and clinical contexts.

Biopsy is a medical test in which a small sample of tissue is removed for examination under a microscope. The term is commonly used in clinical settings to diagnose disease, guide treatment, or assess prognosis. It refers to the process of taking tissue, often via a needle, endoscope, or surgical procedure, for microscopic analysis.

Blepharospasm is a medical noun describing a reflex or intermittent, involuntary contraction of the eyelid muscles. It can cause frequent blinking or eyelid twitching, sometimes with spasmodic closure. The term is used in clinical contexts to denote this dystonic eyelid movement disorder, often associated with neurological or ocular factors.

Bronchitis is a short- or long-term inflammation of the bronchial tubes, the airways that carry air to your lungs. It typically causes coughing, mucus production, and sometimes fever or chest discomfort. Acute bronchitis often follows a viral infection, while chronic bronchitis is a long-term condition linked to smoking or irritants.

Bronchoscopy is a medical procedure that allows doctors to view the inside of the airways and lungs using a thin, flexible tube equipped with a camera. It is performed to diagnose or treat conditions affecting the respiratory tract. The term combines bronchoscope with the -y suffix, indicating a procedure or instrument related to the bronchoscope.

Cardiomyopathy is a disease of the heart muscle that can weaken its ability to pump blood. It encompasses several subtypes characterized by structural or functional changes in the myocardium, leading to heart failure symptoms or arrhythmias. The term combines cardio- (heart) with myo- (muscle) and -pathy (disease).

Cataract is a large, clouding of the lens inside the eye that reduces vision; it can also refer to a waterfall or a sudden rush of water in a stream. In medicine, it denotes lens opacity that often develops with aging, while in geology or meteorology it can describe a cascading appearance. The term typically appears in clinical context or descriptive, non-technical writing.
