Does ureter have submucosa
No
What is interesting about the muscular layer of ureter
inner longitundinal
outer circular

cant distinguish between lamina propria and submucosa
What do the three tunica muscularis layers make up in the bladder
DETRUSOR MUSCLE

middle circular-sphincter muscle
outer longitudinal
