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.
Sensory: The three terminal branches of CN V innervate the skin, mucous membranes and sinuses of the face. Their distribution pattern is similar to the dermatome supply of spinal nerves (except there is little overlap in the supply of the divisions). Motor: Only the mandibular branch of CN V has motor fibres. It innervates the muscles of mastication: medial pterygoid, lateral pterygoid, masseter and temporalis. The mandibular nerve also supplies other 1st pharyngeal arch derivatives: anterior belly of digastric, tensor veli palatini and tensor tympani.
