Exempel på hur man kan använda MESONEPHRIC i en mening

• The mesonephric duct, also known as the Wolffian duct, archinephric duct, Leydig's duct or nephric duct, is a paired organ that develops in the early stages of embryonic development in humans and other mammals.
• Gartner's duct, also known as Gartner's canal or the ductus longitudinalis epoophori, is a potential embryological remnant in human female development of the mesonephric duct in the development of the urinary and reproductive organs.
• Congenital abnormalities of the mesonephric duct in males can lead to the formation of a ureterocele, which often coincide with ipsilateral agenesis of the kidney (atrophic kidney) and seminal vesicle cysts, this is known as Zinner Syndrome.
• Embryologically, the trigone of the bladder is derived from the caudal end of mesonephric ducts, which is of mesodermal origin (the rest of the bladder is endodermal).
• Each of these consists of a glomerulus, a tuft of capillaries which arises from lateral branches of dorsal aorta and drains into the inferior cardinal vein; a Bowman's capsule, a funnel like structure which surrounds the glomerulus; and a mesonephric tubule, a tube which connects the Bowman's capsule to the mesonephric duct.
• While the epoophoron is located in the lateral portion of the mesosalpinx and mesovarium, the paroophoron (residual remnant of that part of the mesonephric duct that forms the paradidymis in the male) lies more medially in the mesosalpinx.
• The ureteric bud, also known as the metanephric diverticulum, is a protrusion from the mesonephric duct during the development of the urinary and reproductive organs.
• This continues to grow caudalward until it opens into the ventral part of the cloaca; beyond the pronephros it is termed the mesonephric duct.
• The sperm differentiate inside the seminiferous tubules, then swim down these tubes, then through these special mesonephric tubules, and go down inside Wolffian duct, to the coelom and finally to the organ the animal uses to transport sperm into females.
• This structure is derived from the Wolffian duct (mesonephric duct) as opposed to the appendix testis which is derived from the Müllerian duct (paramesonephric duct) remnant.
• Testosterone converts the mesonephric ducts into male accessory structures, including the epididymides, vasa deferentia, and seminal vesicles.
• In the early stages of human development, a human embryo has the precursors of female (paramesonephric or Müllerian ducts) and male (mesonephric ducts or Wolffian) gonads.
• These embryonic structures are the mesonephric ducts (also known as Wolffian ducts) and the paramesonephric ducts, (also known as Müllerian ducts).
• The embryology that explains the pathology of an ectopic ureter is a cephalad origin of the ureteral bud on the mesonephric duct.
• A ureteric bud, arising from the mesonephric (or Wolffian) duct, gives rise to the ureter, as well as other parts of the collective system.
• The Müllerian ducts are also referred to as paramesonephric ducts, referring to ducts next to (para) the mesonephric (Wolffian) duct during foetal development.
• Without the proper induction of ureteric buds and mesonephric ducts by Lim-1 and other transcription factors, nephrogenesis is impaired.
• The epididymis, which is a tube that connects a testicle to a vas deferens in the male reproductive system, evolved by retention of the mesonephric duct during regression and replacement of the mesonephros with the metanephric kidney.
