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.
Clouds are Found at Different Heights. The different types of clouds we see in the sky are located at different heights in the sky. High clouds include cirrus, cirrocumulus, and cirrostratus clouds. These clouds are made up of either ice or water droplets, but they are usually made up of ice crystals. Water clouds tend to have sharp edges, and ice clouds are more wispy.
