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.
Ice, frozen (solid) water, can appear in several ways in the atmosphere. As ice precipitation on the ground we see 2 main forms, snow and hail. Snow is composed of ice crystals that aggregate, in clouds, to form snow flakes.Hail is an aggregate of ice particles of which different types can be identified.Interest in ice crystals began in 1611 when Johannes Kepler published a short work ' On the Six-Cornered Snowflake '.now is composed of ice crystals that aggregate, in clouds, to form snow flakes.
