Gonads

Causation is known to operate from chromosome to gonads, and from gonads to hormones.

The pufferfish contains tetrodotoxin (TTX) produced by bacteria in its gastrointestinal tract, which also is found in its gonads, liver, muscle, and skin, and is one of the most poisonous toxins known.

For the finish, Trent attempted a flying maneuver, but Moxley kicked him in the gonads then hit him with a Paradigm Shift on the entrance ramp.

Gopi, who is intersex — those born with sex characteristics (including genitals, gonads and chromosome patterns) that do not fit typical binary notions of male or female bodies — identifies as gender queer.

Budding sites vary by species; from the tentacle bulbs, the manubrium (above the mouth), or the gonads of hydromedusae.

It also helps to develop the excretory units of the urinary system and the gonads.

It causes the destruction of starfish ovary and eggs to cause castration (the male gonads are usually unaffected).

K Kallmann's syndrome disorder that can include several characteristics such as absence of the sense of smell and decreased functional activity of the gonads (organs that produce sex cells), affecting growth and sexual development.

Nemerteans often have numerous temporary gonads ( ovaries or testes ), and build temporary gonoducts (ducts from which the ova or sperm are emitted), one per gonad, when the ova and sperm are ready.

Pseudohermaphroditism " Pseudohermaphroditism " has, until very recently, been the term used in the medical literature to describe the condition of an individual whose gonads and karyotype do not match the external genitalia in the gender binary sense.

Such de novo mutations are the result of a germ cell mutation or germ cell mosaicism in the gonads of one of the parents, or a mutation in the fertilized egg itself.

The absence of it allows the gonads to continue to develop into ovaries.

The developing wings are present in later stage instars and the gonads start development in the egg stage.

The dorsal tracheae supply oxygen to the dorsal musculature and vessels, while the ventral tracheae supply the ventral musculature and nerve cord, and the visceral tracheae supply the guts, fat bodies, and gonads.

The gonads are located in the stomach lining, and the mature gametes are expelled through the mouth.

The gonads are testes regardless of phenotype due to the influence of the Y chromosome.

The gonads shed immature gametes directly into the body cavity, where they complete their development.

The innermost layer of the cortex, the zona reticularis, produces androgens that are converted to fully functional sex hormones in the gonads and other target organs.

The intermediate mesoderm connects the paraxial mesoderm with the lateral plate, eventually it differentiates into urogenital structures consisting of the kidneys, gonads, their associated ducts, and the adrenal glands.

The most primitive species have a pair of gonads in every segment, but most species exhibit some degree of specialisation.
