both the cortex and medulla are formed mainly of numerous ____ tubules.
uriniferous
41
Between the tubules is an extensive ___network.
capillary
42
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
43
____ (cortical labyrinth) are located between the rays and consist of renal corpuscles and numerous proximal and distal convoluted tubules.
The pars
| convoluta
44
___ convoluted tubules are longer than ___tubules and comprise the major portion of the cortex.
Proximal
| distal
45
what has: the apical ends their epithelial cells present a scalloped appearance and possess a brush border.
proximal convoluted tubules
46
Epithelial cells of ___convoluted
| tubules lack a brush border and have a flat, smooth apical surface.
distal
47
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,
48
In the kideny, the ____ should also be identified. Their cuboidal cells have distinct boundaries and clear, faintly stained cytoplasm.
Collecting tubules
49
another name for the capillaries in the kidney
vasa recti
50
In the ____ kidney, the cortex and medulla do not form a continuous, outer and inner strata as in the
mammalian kidney.
bird
51
In the ___ kidney, large areas of cortex enclose small cone-shaped islands of medulla.
bird
52
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.
```
53
____ nephrons (reptilian type), which lack loops of Henle and possess small renal corpuscles, are found in the cortex.
Cortical
found in avian kidney
54
maculae densa.
between the distal convoluted tubule and the glomerulus, point of control.
tells what should be re- absorbed
55
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)
56
equine renal pelvis and proximal third of the ureter have ____ glands in the lamina propria.
simple branched tubuloacinar mucous
