16
Q

Uniferous tubules

A

Consist of

excretory and collecting part

17
Q

Collecting part

A

Junctionla tubules that join together to form ducts of Bellni >minor calyces> ureter > bladder

18
Q

Juxtaglomerular Apparatus

A

consists of

  1. Macula Densa- cells of DCT sensitive to Aldosterone and ions
  2. Juxtaglomerular Cells-epitheiloid cells in media of afferent arteriole secrete renin
  3. Mesangial cells- act as messenger cells
19
Q

Blood supply of kidney

A

Renal Artery- 4 ant and 1 post branch

Segmental> lobar> interlobar> arcuate >interlobular>afferent arteriole> glomerulus >efferent arteriole

20
Q

Lymphatics

A

Lateral aortic nodes

21
Q

Nerve supply

A

Renal plexus via celiac plexus
SNS T10-T11
PSNS- Lesser splanchnic

22
Q

In surgical procedures of kiney there is risk of

A

opening the pleural cavity

23
Q

Renal angle

A

Angle between erector spinae and 12th rib

tendereness of kidney is elicited by placing pressure over here

24
Q

Blood and pus of the kidney cannot cross to the opposite side due to

A

Fascial septum and midline attatchement of reenal fascia

25
Polycystic kidneys most often lead to
hypertension
26
Kidney stones lie
on the body of vertebra
27
Podocytes
Large stellate cell with foot processes | Maintain filteration barrier
28
Slit pores
Narrow clefts between podocytes
29
Types of nephrons
1. Cortical: - majority - present in outer 2/3rd - Shorter loop of henle 2. Juxtamedullary: - present in inner 1/3rd - loop of henle extends deep into medulla - Ascending limb has thick and thin portions
30
Filtration barrier
Consists of 1. Fenestrated glomerular endothelium 2. basal lamina 2. foot processes of podocytes Permits the passage of water, ions and small molecules into the space but prevents passage of large and irregular nolecules
31
Polycystic kidneys
Nonunion of excretory and collecting parts of kidney
32
Horshoe kidney
Fusion of lower poles of kidneys
33
Early pelvis postion of kidney persists
Renal artery arises from common iliac
