Temp files are usually files left over from a setup. Sometimes they get cleaned up, but yours should never have been allowed to get to large. Do a search for .tmp files on the system. Select them all> Delete. The only exception is if you have recently in last day or two installed new software. If so, that file should be allowed to remain for up to a week.
The pituitary gland is the smallest endocrine gland in the human body.
The pituitary gland (or hypophysis) is an endocrine gland about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. It is a protrusion off the bottom of the hypothalamus at the base of the brain, and rests in a small, bony cavity (sella turcica) covered by a dural fold (diaphragma sellae).
