Q

what is the mnemonic for retroperitoneal organs?

S: suprarenal (adrenal) gland
A: aorta/IVC
D: duodenum (second and third part)

P: pancreas (except tail)
U: ureters
C: colon (ascending and descending)
K: kidneys
E: (o)esophagus
R: rectum

Q
  • the renal veins are ……. to the renal arteries
  • aorta bifurcates at the level of ……
  • the common iliac arteries are …… to the common iliac veins
A

anterior

umbilicus

anterior

21
Q

lymph from kidneys goes to…..

lymph from ureters goes to…..

A

lumar nodes (AA nodes from left kidney and IVC nodes take lymph from right kidney)

Lumbar and iliac nodes take lymph from ureters

Q

where wre the common sites of ureteric constriction?

A

pelviureteric junction

ureter crossing anterior aspect of the common iliac artery (often crosses the bifurcation)

ureteric orifice (opening into one corner of the trigone on the floor of the bladder)

25
Q

what is hydronephrosis?

A

Hydronephrosis – “water inside the kidney”

urine back pressure into the calyces compresses the nephrons within the medullary pyramids leading to renal failure

acute hydronephrosis causes painful stretching of the renal capsule

kidney enlargement due to unilateral hydronephrosis is palpable during clinical examination

26
Q

which is the only part of the renal system under somatic motor control?

A

external sphincter and levator ani

27
Q

what parts of the renal sensory sytem are viceral and what is somatic

A

all visceral sensory with the exception of somatic sensory in the perineum

28
Q

between what spinal cord levels do sympathetic fibres leave the spinal cord to join the sympathetic chain?

A

thoracolumbar outflow is between levels T1-L2

29
Q

how do sympathetic nerve fibres get from the CNS to the ureters, kidneys and bladder?

A

they exit the spinal cord between levels T10-L2

they pass through the sympathetic chain without synapsing

they travel within abdominopelvic splanchnic nerves

and synapse at abdominal sympathetic ganglia around the abdominal aorta

after synapsing they travel alongside arteries supplying the organs and join with parasympathetic and visceral sensory nerves to form a periarterial plexus

30
Q

how do parasympathetic nerves leave the cns to supply the kidneys, ureter and bladder?

A

the vagus nerve supplies the kidneys

parasympathetic nerves from spinal nerves S2, S3 and S4 supply the bladder

31
Q

the only parts of the renal system that somatic fibres go to are……

A

those within the perineum, e.g the urethra (distal to the pelvic floor) and its sphincter (external urethral sphincter and levator ani)

32
Q

what nerve somatic nerve supplies the urethra and where does come from?

A

pudendal nerve

S2, S3, S4

33
Q

where is pain from the kidneys, ureters, bladder and urethra usually felt?

A

kidneys- loin

ureters- loin to groin

bladder- suprapubic midline

urethra- perineum

34
Q

what do nerve fibres entering and leaving at S2-S4 do?

A

visceral afferents transmit pain signals from urethra

pudendal nerve carries somatic motor nerve fibres that control external urethral sphincter

S3 and S4 form the nerve of the levator ani (Somatic Motor)

parasympathetic nerves also exit at S2-S4

35
Q

which spinal nerve rami form plexuses?

A

anterior

36
Q
  • the majority of nerves in a plexus carry what type of nerve fibres?
A

somatic motor, somatic sensory and sympathetic

37
Q

nerves from the lumbar plexus supply the ……

nerves from the sacral plexus supply the…. and…..

A

lumbar plexus- lower limbs

sacral plexus- lower limbs and peroneum

38
Q

what are the nerve roots of the sciatic, obturator, femoral and later cutaneuos nerve of the thigh

A

sciatic- L4-S3

Femoral and Obturator- L2-L4

Lateral Cutaneous Nerve of the Thigh- L2-L3
