At the level of the iliac tubercle, a bony prominence on the lateral aspect of the crest 5 cm posterior to the anterior superior iliac spine, the FL is preferentially thickened and this represents the origin of the ITB.
The highest layer of earths atmosphere is the exosphere. The inner core has the most or highest amount of density (iron/nickel). I think its the core of the Earth with highest temperature with  6000 degree Celsius. The crust is the layer of the Earth that has the the lowest density. It depends a bit on what you consider being a part.
The Earth has many layers. The three main layers of the Earth are: The crust (The outermost layer of the Earth). The mantle (Middle layer of the Earth) and. The core (Inner layers of the Earth). The crust is the outermost layer of the Earth and the thinnest of the layers. The Earth's crust is where the mountains, hills, valleys, plains, lakes and oceans are formed. The mantle is the largest layer of the Earth. The mantle is much hotter than the crust, just as the core is much hotter than the mantle.
