Flashcards in Unit 3: Kidney Deck (25):
1

Hiatus of diaphragm

Caval (IVC) at T8, Esophageal at T10, aortic at T12

2

4 Lumbar spinal nerves

iliohypogastric (anterior abdominal wall), pudential (perineum), obturator and ilioinguinal (medial thigh), genitofemoral (genitalia)

3

Lateral femoral cutaneous

runs on iliacus medial to ASIS

4

Femoral Nerve

lateral to psoas, innerv iliacus, hip flexor/knee extensor

5

Anterior femoral cutaneous

L2-L4 from femoral, medial half of thigh

6

Obturator

innervate adductor of thigh, from medial border of psoas muscle

7

Genitofemoral

pierces psoas and runs on anterior surface

8

Kidneys are essential for maintaining?

Proper electrolyte balance of the body

9

Kidney anatomy

Located retroperitoneally on posterior ab wall, T12 - L3; right lower than left; lies behind colon, jejunum, liver, stomach and spleen

10

Kidney functions

control H2O and electrolyte balance, maintain acid base balance, excrete N, Urea, creatinine, drugs, and toxins, returns soluble nutrients

11

Kidney produce

erythropoesis and renin to maintain BP

12

Order of kidney vessels

Vein anterior to artery, anterior to ureter

13

Kidney held in place by?

adipose tissue, renal fascia, fibrous capsule of connective tissue, and renal vessels

14

Microscopic anatomy of kidney

pyramids separated by columns (passage of vessels), lobe= pyramid+ cap of cortex, subdivided in to lobule; separated by interlobular artery, central core- medullary ray; renal tubules

15

Renal tubule

nephron- produces filtrate, collecting tubule-modifies filtrate to produce urine, nephron drains to collecting tubule, collecting duct, pelvis and ureter

16

Kidney blood supply

receives blood from renal a, divide into 5 segmental artery, then interlobar, and arcuate a, interlobular a, then cap, interlobular v, arctuate v, interlobar v, and renal v

17

Kidney innervation

Sympathetic and parasympathetic via renal nerve plexus

18

Ureters

smooth muscular conducting tubes that transport urine to bladder, retroperitoneally at tips of transverse processes courses along bladder and enters inferolaterally on posterior surface

19

3 transition points were connective tissue tethers ureters

at ureter pelvic junction, crossing at external iliac, and transverses the bladder

20

Ureter blood supply

renal arter (ureteric branch), gonadal artery, aorta, common iliac, veins: ureteric and gonadal

21

Ureter innervation

renal, abdominal aortic, and superior hypogastric plexi, referred pain to spinal ganglia (T11-L2); kidney stone: stone descends, pain descends

22

Suprarenal glands

on superior medial surface of kidney between kidney and diaphragm, hang from diaphragm by extensions of renal fascia, barely attached by thin septum

23

2 Parts of suprarenal gland

cortex: secretes corticosteroids, mineralocorticoids and androgens; medulla: secretes catacholamines

24

Suprarenal gland blood supply

sup. suprarenal: inferior phrenic to inferior phrenic and sup. suprarenal; middle suprarenal (aorta); and inferior suprarenal (renal); vein: suprarenal into IVC or renal vein

25

Suprarenal innnervation

Fibers from celiac plexus and all splanchnic nerves, terminate in medulla
