In contrast, the Chrysler Building employed a very large 125 ft (38 m) spire secretly assembled inside the building to claim the title of world's tallest building with a total height of 1,048 ft (319 m), although it had a lower top occupied floor and a shorter height when both buildings' spires were excluded.
The nucleolus is a distinct structure in the nucleus of the cell composed of filamentous and granular material. It is the site of synthesis and processing of ribosomal RNA and the assembly of this RNA with ribosomal proteins into ribosomal subunits.
Annulus Fibrosus and Nucleus Pulposus. Intervertebral discs are composed of an annulus fibrosus and a nucleus pulposus. The annulus fibrosus is a strong radial tireâlike structure made up of lamellae; concentric sheets of collagen fibers connected to the vertebral end plates.The sheets are orientated at various angles.he annulus fibrosus encloses the nucleus pulposus. Although both the annulus fibrosus and nucleus pulposus are composed of water, collagen, and proteoglycans (PGs), the amount of fluid (water and PGs) is greatest in the nucleus pulposus. PG molecules are important because they attract and retain water.
