-Psoas located posterior lateraly

Question 3

this fascia anchors the kidneys and adrenal glands and limits infection

Answer 3

Answer 4

Renal Parenchyma

Question 5

Bands of cortical tissue within the kidneys, and separate the medullary pyramids

Answer 5

Question 6

what is the echogenicity of the different layers of the kidneys from light to darkest

Answer 6

-renal sinus
-parenchyma
-renal cortex
-medullary pyramids

Question 7

blood supply of the kidney

Answer 7

Question 8

Lab tests for kidneys

Answer 8

-BUN (Blood Urea Nitrogen): assess renal function and & measures kidneys ability to rid the body of waste
-Creatinine
-Glomerular Filtration Rate (GFR)
-Clearance Tests: patients ability to urinate and how much

Question 9

Functions of the kidney

Answer 9

-make urine and excrete waste
-regulate blood volume
-regulate blood pressure
-reabsorption of water and sodium back into the body

Question 10

this hormone is used to increase water reabsorption, constrict blood vessels, regulate sodium homeostasis

Answer 10

ADH (Antidiuretic Hormone)

Question 11

this hormone helps the kidneys to increase sodium absorption, increase water and potassium excretion

Answer 11

Aldosterone

Dromerdary Hump

Question 14

an enlargement between the renal cortex and medullary pyramids; same echogenicity as a normal cortex

Answer 14

Hypertrophied Column of Bertin

Question 15

Answer 15

Horseshoe Kidney

Question 16

Kidneys develope outside the renal fossa including the pelvis, lower abdomen, and intrathoracic

Answer 16

renal ectopia

Question 17

A multiple amount of fluid filled cysts develop consuming the entire organ and affecting both kidneys; can spread to other organs; developed in adulthood; dominant inheritance

Answer 17

APKD (Adult Polycystic Kidney Disease)

Question 18

multiple cysts develop consuming the entire kidney, manifests in fetal development, stays within the kidneys; recessive inheritance can skip a generation

Answer 18

IPKD (Infant Polycystic Kidney Disease)

Question 19

Answer 23

Hydronephrosis
Grade 1: pelviectasis, light mild version
Grade 2: mild
