Like in a greenhouse, greenhouse gasses let radiation from the sun reach Earth (the 'inside' of the greenhouse) but won't let the Earth reflect radiation. This is exactly what â¦ greenhouses do. Through the glass walls, the sunlight can come in, but once the rays are inside, the heat is trapped.
The sternohyoid muscle's main function is the depression of the hyoid bone. The hyoid bone is located below the mandible, or lower jaw, and is a U shaped bone that is partially responsible for tongue movement and the action of swallowing. The sternohyoid is one of a pair of muscles responsible for this action.
