middle circular layer outer longitudinal layer
• Adventitia: the connective tissue
• D-6 Urethra, mammal female • "E," stratified squamous epithelium with a
supporting connective tissue lamina propria.
• The muscularis, "M," consists of smooth muscle fiber bundles
• (an inner longitudinal layer,)• a middle circular layer, • an irregular outer longitudinal layer.
