Answer:
At the base of Actinopterygii
*This is a unique characteristic of this group.
Explanation:
A peculiar characteristic organ observed in ray-finned fish (as well as in Sarcopterygii, or lobe-finned fish) but not in cartilaginous fish like shark is the swim bladder.
This organ is often described to be a sac containing gas. It helps these set of fish adjust its buoyancy and its position in the water by regulating the concentration of gas present in it.
The swim bladder is formed as a pouch coming off the embryonic digestive tract, and in chondrosteans and holosteans, with a set of teleosts e.g. the eels, it maintains an open pathway to the esophagus. In majority of the bony fish, the swim bladder is totally sealed off, as gas levels in their swim bladder are regulated by producing gas into the bladder via a network of capillaries, the rete mirabile (Latin word for "marvelous net").
The swim bladder is homologous to the lungs of tetrapods. Since they are formed in the same vein. Few fishes that have an open swim bladder employs it as a breathing organ.
Hyponatremia and decreased urine output are exhibited with syndrome of inappropriate secretion of antidiuretic hormone (siadh).
<h3>What is secretion of antidiuretic hormone (siadh)?</h3>
Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is a condition in which the body produces too much antidiuretic hormone (ADH). This hormone helps the kidneys control the amount of water the body loses through urine. SIADH causes the body to retain excess water. ADH is a substance that is naturally produced in an area of the brain called the hypothalamus. It is then released from the pituitary gland at the base of the brain.
There are many reasons why the body needs to produce large amounts of ADH. Common situations where ADH is (improperly) released into the blood when it shouldn't be produced include:
- During surgery General anesthesia
- Brain disorders such as trauma, infections and stroke
- Brain surgery involving the hypothalamus
- Pulmonary disorders such as tuberculosis, cancer, chronic infections and pneumonia
- Substance abuse
Rare causes include: There is a thing Pituitary
- Leukemia and cancer of the small intestine, pancreas and brain
- Psychiatric disorders
