tract (trakt)

1. a region, principally one of some length.

2. a bundle of nerve fibers having a common origin, function, and termination.

3. a number of organs, arranged in series and serving a common function.

alimentary tract  see under canal.

atriohisian tracts  myocardial fibers that bypass the physiologic delay of the atrioventricular node and connect the atrium directly to the bundle of His, allowing preexcitation of the ventricle.

biliary tract  the organs, ducts, etc., participating in secretion (the liver), storage (the gallbladder), and delivery (hepatic and bile ducts) of bile into the duodenum.

digestive tract  alimentary canal.

dorsolateral tract  a group of nerve fibers in the lateral funiculus of the spinal cord dorsal to the posterior column.

extracorticospinal tract , extrapyramidal tract extrapyramidal system.

Flechsig's tract  posterior spinocerebellar t.

gastrointestinal tract  the stomach and intestine in continuity.

genitourinary tract  urogenital system.

Gowers' tract  anterior spinocerebellar t.

iliotibial tract  a thickened longitudinal band of fascia lata extending from the tensor muscle downward to the lateral condyle of the tibia.

intestinal tract  the small and large intestines in continuity.

nigrostriatal tract  a bundle of nerve fibers extending from the substantia nigra to the globus pallidus and putamen in the corpus striatum; injury to it may be a cause of parkinsonism.

optic tract  the nerve tract proceeding backward from the optic chiasm, around the cerebral peduncle, and dividing into a lateral and medial root, which end in the superior colliculus and lateral geniculate body, respectively.

pyramidal tract  two groups of nerve fibers arising in the brain and passing down through the spinal cord to motor cells in the anterior horns.

respiratory tract  see under system.

reticulospinal tract  a group of fibers arising mostly from the reticular formation of the pons and medulla oblongata; chiefly homolateral, the fibers descend in the ventral and lateral funiculi to most levels of the spinal cord.

spinocerebellar tract, anterior  a group of nerve fibers in the lateral funiculus of the spinal cord, arising mostly in the gray matter of the opposite side, and ascending to the cerebellum through the superior cerebellar peduncle.

spinocerebellar tract, posterior  a group of nerve fibers in the lateral funiculus of the spinal cord, arising mostly from the nucleus thoracicus, and ascending to the cerebellum through the inferior cerebellar peduncle.

spinothalamic tract  a group of nerve fibers in the lateral funiculus of the spinal cord that arise in the opposite gray matter and ascend to the thalamus, carrying the sensory impulses activated by pain and temperature.

urinary tract 

1. see under system.

2. sometimes more specifically the conduits leading from the pelvis of the kidneys to the urinary meatus.

urogenital tract  see under system.

uveal tract  the vascular tunic of the eye, comprising the choroid, ciliary body, and iris.

Urinary tract

The system of organs that produces and expels urine from the body. This system begins at the kidneys, where the urine is formed; passes through the bladder; and, ends at the urethra, where urine is expelled.

Mentioned in: Bladder Stones, Erythromycins, Fluoroquinolones, Sulfonamides

---

urinary tract,

all organs and ducts involved in the secretion and elimination of urine from the body. Also called urinary system.

---

urinary tract,

n all organs and ducts involved in the secretion and elimination of urine from the body, principally the kidney, ureter, bladder, and urethra.

urinary tract infection,

n an infection of one or more structures in the urinary tract. Gram-negative bacteria cause most of these infections.

---

urinary

pertaining to the urine; containing or secreting urine.

---

urinary bile pigment

bilirubin and urobilinogen are found in the urine of normal animals.

urinary calculi

see urolith, urolithiasis.

urinary diversion

various surgical procedures involving the ureters, bladder or urethra may be used to alter the usual route of urine flow, thereby bypassing portions of the urinary tract, usually the bladder and/or urethra. Ureters, bladder or urethra are transplanted or anastomosed to the bowel or placed so urine exits at an orifice created through the skin. See also ureteroileostomy, trigonal-colonic anastomosis, ureterocolostomy, transureteroureterostomy.

urinary flow monitor

periodic measurement of the amount of urine secreted. In an anesthetized animal a catheter draining into a calibrated container is used. In a conscious animal a clamped-off, self-retaining catheter is inserted and drained at intervals. A metabolism cage is an alternative.

urinary flowmetry

the measure of urinary flow rates.

urinary incontinence

an inability to control urination with the involuntary passage of urine. Most commonly occurs in dogs due to congenital abnormalities of the ureters or urethra. Other causes include congenital or acquired defects in nervous control of micturition, neoplastic or inflammatory disease of the lower urinary tract, and prostate gland and endocrine abnormalities.

urinary obstruction

urethral or ureteral obstruction often caused by lodgement of a urinary calculus in the narrow lumen. Constriction of urethra due to hyperplastic prostate in male dogs.

urinary pole

the point on the glomerulus where the proximal convoluted tubule exits.

urinary pooling

see urovagina.

urinary system, urinary tract

the system formed in the body by the kidneys, the urinary bladder (2), the ureters and the urethra, the organs concerned in the production and excretion of urine.

urinary territorial marking

see spraying.

urinary tract
