Renal and Urinary
| Question | Answer |
|---|---|
| Atony | The absence or lack of normal tone or strength. |
| Catecholamine | The class of neurotransmitters that includes dopamine, epinephrine, and norepinephrine. When given therapeutically, catecholamines mimic the effects of stimulating the sympathetic nervous system. |
| Detrusor | The smooth muscle of the urinary bladder that is mainly responsible for emptying the bladder during urination. |
| Detrusor areflexia | The absence of detrusor contractions. |
| Erythropoiesis | The formation of erythrocytes. |
| Erythropoietin | A glycoprotein hormone secreted mainly by the kidney; it acts on stem cells of the bone marrow to stimulate red blood cell production. |
| Hematuria | Blood in the urine. |
| Hypertension | Persistently high blood pressure. |
| Hypertonus | The state characterized by an increased tonicity or tension. |
| Hypokalemia | Abnormally low potassium concentration in the blood. |
| Lower Motor Neurons | Peripheral neurons whose cell bodies lie in the central gray columns of the spinal cord and whose terminations lie in skeletal muscle. A sufficient number of lesions of lower motor neurons cause muscles supplied by the nerve to atrophy. |
| Nephrology | The study of the urinary or renal system. |
| Nephron | The basic functional unit of the kidney. |
| Polydipsia | Excessive thirst manifested by increased water consumption. |
| Polyuria | Excessive urination. |
| Retroperitoneal | Located behind the peritoneum. |
| Upper Motor Neurons | A sufficient number of lesions of upper motor neurons interrupt the inhibitory effect that upper motor neurons have on lower motor neurons, resulting in exaggerated or hyperactive reflexes. |
| Uremia | Abnormally high concentrations of urea, creatinine, and other nitrogenous end products of protein and amino acid metabolism in the blood. |
| Urinary Incontinence | Lack of voluntary control over the normal excretion of urine. |
| Urinary Tract Infection | Infection of the urinary tract. Infection may be localized or may affect the entire urinary tract. |
