A pithed frog is a frog that has its spinal cord or cerebral cortex pierced, severed or scrambled in order to kill it or make it insensible for experimental purposes such as disection.
The nervous system is part of the respiratory and circulatory system. It is the brain, spinal cord, and nerves. When the nervous system is destroyed the heart of a double pithed frog contracts in an organized manner. This is exemplified in other animals as well for instance in alligators because the nerves for some time after death continue to fire. The firing of nerves send electrical signals to the heart and therefore pump it.
No, a stretch reflex cannot be elicited in a pithed animal because the central nervous system has been removed, including the brain and spinal cord which are necessary for the reflex to occur. The absence of a functional central nervous system prevents the sensory information from being processed and the motor response from being generated.

Pithed means to remove the pith from the spinal cord, effectively paralyzing and most likely killing the organism. This technique is used many times with frogs to assure the subject is brain dead before tests can be run on nerves. They are terminated before the beginning of the experiment to have fresh nerves to run compound action potential tests on.
