The endocrine system is composed of the hypothalamic-pituitary axis, the thyroid gland, the parathyroid glands, the adrenal glands, the islet cell tissue of the pancreas and the gonads. |
|
For example, a decrease in fish gonad size would be considered large if the magnitude of this effect was equal to or greater than the CES for fish gonads. |
|
They found exposure to Atrazine at levels well below those found in the lakes, rivers, streams, rainwater and drinking water, causing frogs to mature with multiple, mixed gonads thereby becoming demasculinized. |
|
Mill C can conduct the investigation of cause and investigation of solution studies individually or as part of the national study on reduced fish gonads. |
|
In particular, gonadal shielding should be used when the gonads are in or within five centimetres of the primary beam but only if the shielding does not exclude information or interfere with the study. |
|
Other conditions, such as Androgen Insensitivity Syndrome, where an individual is born with female genitalia, but male gonads, also occurring in about 1 in 20,000 births, often goes undetected until puberty. |
|
Bilateral gonadectomy was performed and histological examination confirmed that both gonads had features consistent with streak ovaries. |
|
|
As the blood flow diminishes, the cells within the gonads die and dehydrate. |
|
An exception is the Ophiocanopidae, in which the gonads do not open into bursae and are instead paired in a chain along the basal arm joints. |
|
The gonads of both male and female sea urchins, usually called sea urchin roe or corals, are culinary delicacies in many parts of the world. |
|
In 1777, the Italian Carlo Mondini located an eel's gonads and demonstrated that eels are a kind of fish. |
|
In most species, gonads are paired organs of similar size, which can be partially or totally fused. |
|
Although molluscs are coelomates, their coeloms are reduced to fairly small spaces enclosing the heart and gonads. |
