If your professor walked into your room right now and caught you cheating on this quiz you would try to immediately lie about it.  That is considered a stretch reflex.  

The Vagus nerve has sensory and motor functions and unlike many cranial nerves affects body parts below the head and shoulders.

In the Spinal Cord the white matter is superficial to the grey matter and the efferent neurons would be more responsible for moving your fingers right now.  

The Integumentary system can bypass the peripheral nervous system and connect directly with the central nervous system.  

The smallest unit of life is the cell.  

The CNS includes the cranial nerves because they innervate the structures above the shoulders.

A 64-pound object is suspended from a spring that has a natural length of 16 inches.  When the weight is applied the spring has a total length of 22 inches.  At the start, the object is lifted upward a total of 6 inches and given a downward velocity of 0.25 ft/sec.   An external force, F(t) = 5sin(ωt), is applied and the system experiences resonance.  The damping force is 20 when the velocity is 2 ft/sec.  Compute the position equation. Over an extended period of time the objects position behaves like what position equation? Make no gaps in your mathematical logic.  Gaps will result in a points deductions.  Do not enter anything in the text box below.

A diesel locomotive holds 1500 liters of engine oil.  The oil specifications require 1 gram (1000 ppm) of zinc per liter of oil to protect the engine from excessive wear in the bearings and other internal parts.  At the two-month service interval, a locomotive engine is determined to have 1500 liters of oil that contains 0.8 grams of zinc per liter of oil.  Replacement oil with a concentration of 1.5 grams of zinc per liter is pumped into ther reservior at the rate of 10 liters per minute.  Well-mixed oil is removed from the engine at the same rate.  How many minutes should this process of replacing oil be allowed to continue to restore the oil to 1 gram of zinc per liter?  NOTE:  If the oil has an excess of zinc, it will damage the engine.
