Parathyroid chief cell. Parathyroid chief cells (also called parathyroid principal cells or simply parathyroid cells) are cells in the parathyroid glands which produce parathyroid hormone. The end result of increased secretion by the chief cells of a parathyroid gland is an increase in the serum level of Calcium. Parathyroid chief cells constitute one of the few cell types of the body that regulate intracellular calcium levels as a consequence of extracellular (or serum) changes in calcium concentration.
According to the National Basketball Association, basketball courts should be rectangular shapes that are 94 feet long and 50 feet wide, with inner dimensions including a 23 foot, 9-inch semicircular three-point arc at either end of the court; however, dimensions for other leagues and age groups may differ.
The location will vary depending on the size of the court. 1  An NBA court locates the hoop 4-feet from the end of the court play area. 2  The pole should be set at least 18â deep in the slab. 3  Cross brace with stakes and forming lumber to get the pole vertical.4  Check the pole with a plumb bob or level. Is it enough for a full size court or half court? 2  To get a better picture of how a basketball court will fit in the yard, take several wooden stakes and string, mark off the corners of the proposed court, and pound the stakes into the grass or dirt to see what size court is feasible for the property.
