No - except by inducing a gag reflex.
And note that this merely empties the stomach - not the intestines.
Maybe sticking your fingers down your throat triggers movement of stomach bulk to dislodge it ?
Stimulating the gag reflex in the throat is usually enough to do it if you are determined (see bulimia). Otherwise, vomit-inducing substances such as ipecac oil will suffice. You worded your question poorly. Reverse peristalsis is far more commonly known as vomiting.
Morphine
causes a wave of esophageal contraction called peristalsis. Peristalsis pushes food along the esophagus. Normally, peristalsis causes the esophageal sphincter to relax and allow food into the stomach.
Peristalsis is the contraction of smooth muscles that cause food to move throughout the digestive tract.
Bad bulbs can be the cause of your reverse lights not working on your 1999 Toyota Tacoma. A problem with the reverse switch or bad wires can also be the cause of your reverse lights not working.
Ileus
Peristalsis is the normal rhythmic contraction of the intestinal muscles that moves ingesta through the tract - your dog cannot, by definition, be suffering from this as it is normal. However, there are some diseases that affect movement of ingesta through the intestinal tract. Causes range from congenital disorders to infections to autoimmune disease to cancer, and the treatment options vary based upon the cause. Your veterinarian would be a better person to ask this question of, as he/she will have a better idea of the underlying cause.
There can be several things that will cause your transmission not go into reverse. The most common cause is the gear in the transmission is worn.
What would cause the 1995 Nissan Pathfinder not to go in forward or reverse?
Yes.
No. In most vehicles reverse is also high gear, on automatics.
