gubernaculum การใช้

• The males also have paired gubernaculum and bursa.
• The gubernaculum grows into a thick cord.
• Developing on the outside surface of each testis is a Phibro muscular cord called the gubernaculum.
• The shape and size of the gubernaculum are often important characters for the systematics of nematodes.
• The testis is outstretched . gubernaculum is well developed and there is a bursa enveloping the tail.
• The gubernaculum is another organ of the nematode male copulatory system, which guides the spicules during copulation.
• Embryologically, each ovary ( which forms from the gonadal ridge ) is connected to a band of mesoderm, the gubernaculum.
• By the fifth month the lower part of the gubernaculum still is a thick cord, while the upper part has disappeared.
• Other gonad-infecting species differ from this one by possessing a smooth gubernaculum, and their spicules being of different lengths.
• Cryptorchidism in AMH deficiency suggests that AMH may play a role in transabdominal testicular descent, perhaps by facilitating contraction of the gubernaculum.
• This species is characterized mainly by : length of spicules and length and structure of its gubernaculum; body size; location in host and types of hosts.
• It is distinguished from its cogenerates by the gubernaculum structure in males, as well as the shape and structure of the females'cephalic and caudal ends, and their oesophagus.
• During the latter parts of urogenital development, the gubernaculum forms a long fibrous band of connective tissue stretching from the ovary to the uterus, and then continuing into the labium majus.
• This species is characterized mainly by : length of spicules and length and structure of its gubernaculum; structure of male caudal end; body size; location in host and types of hosts.
• The descent of the testes to its final location at the anterior abdominal wall, followed by the development of the gubernaculum, which subsequently pulls and translocates the testis down into the developing scrotum.
• All of the structures remain attached to the testis and form what is known as the spermatic cord by the time the testis is in the scrotal sac, the gubernaculum is no more than a remnant of scar like tissue.
• The descent of the testes consists of the opening of a connection from the testis to its final location at the anterior abdominal wall, followed by the development of the gubernaculum, which subsequently pulls and translocates the testis down into the developing scrotum.
• In short, the descent of the testes consists of the opening of a connection from the testis to its final location at the anterior abdominal wall, followed by the development of the gubernaculum, which subsequently pulls and translocates the testis down into the developing scrotum.
• This connective tissue span, the remnant of the gubernaculum is separated into two parts anatomically in the adult; the length between the ovary and the uterus termed the ovarian ligament, and the longer stretch between the uterus and the labium majus, the round ligament of uterus.
• The process by which a testis to send is not well understood but it seems to be associated with the shortening of the gubernaculum, which is attached to the testis and extends to the inguinal canal to the wall of the scrotum as a testis to sense it passes to the side of the urinary bladder and anterior to the symphysis pubis.
