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 found in the low altitude range are indicated by the prefix âstratoâ or by the suffix âstratus.â Their bases are below 2,000 meters (6500 feet) in altitude, and except in cold weather when they can contain ice and snow, they are composed of water droplets. Three types of low altitude clouds are stratus, stratocumulus and nimbostratus. Stratus clouds are gray clouds that often cover the entire sky.
