Glycosuria is the high amount of sugar in urine mainly due to insulin deficiency.

Prolactin secreted from pituitary is responsible for secretion of milk after parturition.

Secondary messengers are low-weight diffusible molecules that are used to relay signals within a cell.

Sodium is an essential nutrient which helps to maintain blood volume and keeps nerves functioning.
