UT103 - Anatomy Flashcards
at what level of vertebrae are the renal arteries located?
L1/L2
which of the renal arteries is longer ?
the right renal artery is longer and courses posterior to the IVC
From anterior to posterior, what is the orientation of the vessels within the renal hilum?
1) renal vein
2) renal artery
3) ureter (most posterior and inferior)
Where are the 3 constrictors of the ureter?
1) at the exit from the renal pelvis
2) at the crossing over the iliac vessels
3) at the entrance into the bladder
Where is the location of the bladder?
subperitoneal and covered by peritoneum
what is the arterial supply to the urinary bladder?
superior and inferior vesicular arteries
what is the trigone of the bladder?
it is a triangular area between the ureteric orifices and the urethra
where do the testicular veins course and drain into?
they course through the inguinal canal; the left drains into the left renal vein and the right one into the inferior vena cava.
what is hydrocele testis?
when fluid accumulates between the visceral and parietal layer of the tunica vaginalis testis
what is contained in the spermatic cord?
1) vas deferens
2) pampiniform plexus of veins
3) testicular artery
4) lymph vessels
5) artery and vein of vas deferens
6) branch of ilioinguinal nerve
7) genital branch of genitofemoral nerve
is the seminal vesicle palpable from rectum?
yes
what does the prostate gland secrete?
acidic secretions that are serous and milky
Describe the cremaster reflex
stroking the medial thigh causes contraction of the cremaster muscle which pulls the testicles up.
Afferent arc: femoral branch of the genitofemoral nerve
efferent arc: genital branch of the genitofemoral nerve
where does the arterial supply to the penis derive from?
internal pudendal artery
what causes erection?
parasympathetic stimulation (S2-S4) via pelvic splanchinic nerves
what causes emission?
sympathetic stimulation (L1/L2)
What causes ejaculation?
contraction of the bulbospongiosus muscle (S2-S4, pudendal nerve)
