Test 2: Lab 15: Urinary Flashcards
in the pars convoluta
in the pars convoluta
proximale 1/3= mucous glands
distal 1/3 = no mucous glands
CT= connective tissue= lamina propria and submucosa
smooth muscle between lamina propria and submucosa layers
cortex surrounds triangle shaped medulla
BIRD kidney
nucleated red blood cells within
Pseudostrified columnar epithelium instead of transitional like in mammals
bird do not have lymph nodes lots of neutrophils in the CT of the lamina propria
both the cortex and medulla are formed mainly of numerous ____ tubules.
uriniferous
Between the tubules is an extensive ___network.
capillary
In the cortex, groups of radially arranged tubules form the ___ (cortical ray or medullary rays),
consisting of collecting tubules and straight portions of nephrons.
pars radiata
____ (cortical labyrinth) are located between the rays and consist of renal corpuscles and numerous proximal and distal convoluted tubules.
The pars
convoluta
___ convoluted tubules are longer than ___tubules and comprise the major portion of the cortex.
Proximal
distal
what has: the apical ends their epithelial cells present a scalloped appearance and possess a brush border.
proximal convoluted tubules
Epithelial cells of ___convoluted
tubules lack a brush border and have a flat, smooth apical surface.
distal
In the ____ , you should be able to identify ascending and descending thick
segments of the loops of Henle as well as thin segments of the loops of Henle.
medulla,
In the kideny, the ____ should also be identified. Their cuboidal cells have distinct boundaries and clear, faintly stained cytoplasm.
Collecting tubules
another name for the capillaries in the kidney
vasa recti
In the ____ kidney, the cortex and medulla do not form a continuous, outer and inner strata as in the
mammalian kidney.
bird
In the ___ kidney, large areas of cortex enclose small cone-shaped islands of medulla.
bird
The bird kidney contains two types of nephrons.
Cortical nephrons (reptilian type), which lack loops of Henle and possess small renal corpuscles, are found in the cortex.
Medullary nephrons (mammalian type) are less common. These have larger renal corpuscles and loops of Henle which extend into the medullary cones.
____ nephrons (reptilian type), which lack loops of Henle and possess small renal corpuscles, are found in the cortex.
Cortical
found in avian kidney
maculae densa.
between the distal convoluted tubule and the glomerulus, point of control.
tells what should be re- absorbed
the proximal 1/3 of the horse ureter, vs the distal
proximal = mucous glands
distal= no mucous glands, 3 layers of muscle (longitudinal, circular, longitudinal)
equine renal pelvis and proximal third of the ureter have ____ glands in the lamina propria.
simple branched tubuloacinar mucous
