The Medulla Oblongata's General Functions. Whereas the pons is located in the upper part of the brainstem, the medulla oblongata is a structure located in the lower half of the brainstem. Just because the medulla oblongata is beneath the pons, doesn't mean it's any less significant. In fact, they often work in tandem on issues such as breathing.
Cirrus are detached clouds in the form of white, delicate filaments or white or mostly white patches or narrow bands. These clouds have a fibrous (hair-like) appearance, or a silky sheen, or both. Cirrus clouds are composed almost exclusively of ice crystals. These crystals are in general very small, a fact, which together with their sparseness, accounts for the semi-transparency of most cirrus clouds.
Cirrus clouds are thin, white clouds that have a wispy, feathery  appearance. They form at heights of 25,000 feet or more. They are  composed of tiny ice crystals, and are aâ¦ssociated with fair or  pleasant weather. They have a hair-like appearance, and the  curled-up ends are very common features.
