turtles, like majority of reptiles use glands located in their nasal passages, tear ducts, etc to secrete excess salt
"They can drink salt water because their supraorbital gland filters excess salt from the bloodstream. The salt is excreted in a concentrated fluid from the nasal passages." http://en.wikipedia.org/wiki/Supraorbital_gland
Penguins have a salt gland, not a sweat gland. The salt gland helps them to excrete excess salt from their bodies, which is particularly useful for penguins that live in marine environments. Sweat glands are not as common in animals that live in cold climates like penguins do.
The secret of the gull's ability to survive drinking salt water lies in a pair of glands in the head, but their function was not eluciadated until a few years ago. Each gland consists of thousands of minute tubes arranged like the bristles on a bottle brush. Where the handle of the brush would be is a central tube communicating with the nasal cavity. A rich supply of fine blood vessels surrounds the gland, which extracts the salt from the blood.
Only mammals have sweat glands, so the albatross doesn't have them. Its salt gland helps it to get rid of the heavy concentrations of salt it ingests with its food and by drinking ocean water. This is a much greater concentration of salt than what mammals handle via sweating, and of course, sweating's primary function is not to rid the body of salt, but rather to cool it, to produce scent, to protect the skin and hair, etc. Mammary glands are even a modified type of sweat gland.
The thyroid gland is often imaged using a salt of iodine-131 as this gland has a high uptake of iodine.
the lack of salt is called Goiter, an enlargement of the thyroid gland.

The adrenal gland is associated with regulating sugar and salt levels in the body, as well as the production of sex hormones like estrogen and testosterone.
Sorry, but you're going to have to ask about a specific gland.
Surgically removing the pituitary gland through the nasal cavity, going through the sphenoid bone/sinuses of the skull.
No, sodium chloride is normal table salt which does not get you high, its also difficult enought to overdose on salt, youd need about 25 spoons of it i think, much more than is in your nasal spray.
