1 yard of dirt = 1.45 tons of dirt   The above is a function guideline, but it really depends on the type of dirt in question, and how wet that dirt is. For baseball dirt Iâ¦ like to use 1 yard = 1.3 tons.
The third division of the trigeminal nerve is the mandibular nerve. This division innervates the lower third of the face which includes the lower lip, the jaw, the preauricular area and the temporal area.
It covers the majority of the temporal bone and lesser portions of the frontal and parietal bones. The upper margin of the muscle follows the superior temporal line. Insertion: The temporal muscle inserts on the coronoid process of the mandible.Action: The temporal muscle acts in unison with the masseter and internal pterygoid muscles to close the jaws. Very importantly, it also helps to retrude or pull back the mandible.he depressors of the mandible act to open the lower jaw widely, a function which the muscles of mastication cannot perform. MUSCLES OF MASTICATION There are four paired muscles of mastication. They are the masseters, the temporals, the internal pterygoids, and the external pterygoids.
