mesonephric การใช้

• Male accessory organs are derived from mesonephric ( wolfian ) ducts.
• Without testosterone and AMH, the mesonephric ducts degenerate and disappear.
• However, some cells of mesonephric origin join the gonadal ridge.
• This part of the frog is called the mesonephric duct.
• It develops from the primitive vena cava and mesonephric veins.
• The kidney ( s ) are drained via mesonephric / archinephric duct.
• Meanwhile, an artery from the dorsal aorta begins extending towards the mesonephric tubule.
• This duct is known as the pronephric duct, mesonephric duct or Wolffian duct.
• These are the mesonephric ducts and paramesonephric ducts.
• In females, the mesonephric ducts regress.
• The prostate forms from the urogenital sinus and the efferent ducts form from the mesonephric tubules.
• They degenerate in males of certain species, but the adjoining mesonephric ducts develop into male reproductive organs.
• The paramesonephric ducts and the mesonephric ducts share a majority of the same mesenchyme due to Hox gene expression.
• In the female the mesonephric ducts regresses, causing the trigone to be less prominent, but still present.
• These embryonic structures are the Wolffian and M黮lerian ducts, also known as mesonephric and paramesonephric ducts, respectively.
• Testosterone converts the mesonephric ducts into male accessory structures, including the epididymis, vas deferens, and seminal vesicle.
• This vesicle then elongates to form the " mesonephric tubule ", attaching to the mesonephric duct on one side.
• This vesicle then elongates to form the " mesonephric tubule ", attaching to the mesonephric duct on one side.
• The eponymous " Kobelt's tubules " are named after him, which are remnants of mesonephric ducts in the paroophoron.
• As it elongates caudally, the pronephric duct induces nearby intermediate mesoderm in the thoracolumbar area to become epithelial tubules called mesonephric tubules.
