Anatomy (Posterior Abdominal Wall) Flashcards
1
Q
Ureter Formation
A
Minor Calyx combine into Major Calyx which combine into Renal Pelvis which turns into Ureter
2
Q
Common Sites For Kidney Stones To Get Stuck (3)
A
- Narrowing of renal pelvis into ureter proper
- Where ureter crosses common iliac artery bifurcation before bending down into pelvis
- penetration of bladder wall
3
Q
Blood Flow Pathway to Nephrons
A
renal a. -> segmental a. -> interlobar a. -> arcuate a. -> interlobular a. -> afferent arteriole
4
Q
Innervation of Suprarenal (Adrenal) Glands (3)
A
- Preganglionic sympathetic fibers synapse in medulla
- Releases epinephrine & norepinephrine
- Exception to the pattern of sympathetic innervation
5
Q
Parasympathetic Innervation Before vs After Transverse Colon
A
Before - Vagus
After - S2, S3, S4
6
Q
Nerves of Lumbar Plexus (7)
A
- Iliohyposgastric
- Ilioinguinal
- Lateral femoral cutaneous
- Genitofemoral
- Femoral
- Obturator
- Lumbosacral trunk
7
Q
Iliohyposgastric Nerve Location & Innervation
A
- (L1) cutaneous innervation of posterolateral gluteal region and suprapubic area. Some motor to abdominal wall.
8
Q
Ilioinguinal Nerve Location & Innervation
A
- (L1) cutaneous innervation of proximal medial thigh and scrotum/mons pubis
- Some motor to abdominal wall
9
Q
Lateral Femoral Cutaneous Nerve Location & Innervation
A
- (L2-L3) cutaneous innervation of lateral side of thigh
10
Q
Genitofemoral Nerve Location & Innervation
A
- (L1-L2) cutaneous innervation of genitalia and thigh
- Genital branch joins spermatic cord to innervate cremaster muscle
11
Q
Femoral Nerve Location & Innervation
A
- (L2-4) innervates anterior region of thigh
12
Q
Obturator Nerve Location & Innervation
A
- (L2-4) innervates medial side of thigh
13
Q
Lumbosacral Trunk Location & Innervation
A
- (L4-5) contributes fibers to sacral plexus
