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.
1 The facial nerve then passes through the parotid gland, which it does not innervate, to form the parotid plexus, which splits into five branches innervating the muscles of facial expression (temporal, zygomatic, buccal, marginal mandibular, cervical). In the tympanic segment, the facial nerve runs through the tympanic cavity, medial to the incus. 2  The pyramidal eminence is the second bend in the facial nerve, where the nerve runs downward as the mastoid segment. 3  In the temporal part of the facial canal, the nerve gives to the stapedius and chorda tympani.
