An abdominal reflex is a superficial neurological reflex stimulated by stroking of the abdomen around the umbilicus. It can be helpful in determining the level of a central nervous system (CNS) lesion. Being a superficial reflex, it is polysynaptic (involving multiple connections between nerves). [1]
A list of reflexes in humans. Abdominal reflex; Accommodation reflex — coordinated changes in the vergence, lens shape and pupil size when looking at a distant object after a near object. Acoustic reflex or attenuation reflex — contraction of the stapedius and tensor tympani muscles in the middle ear in response to high sound intensities.
Muscular defense is a reflex of the abdominal muscles to contract upon mechanical force to the abdomen, and serves as protection. It is a visceromotor reflex , since the parietal peritoneum and viscera are involved in generating the reflex.
The simplest reflex is initiated by a stimulus, which activates an afferent nerve. The signal is then passed to a response neuron, which generates a response. Reflexes are found with varying levels of complexity in organisms with a nervous system. A reflex occurs via neural pathways in the nervous system called reflex arcs.

The gastrocolic reflex or gastrocolic response is a physiological reflex that controls the motility, or peristalsis, of the gastrointestinal tract following a meal. It involves an increase in motility of the colon consisting primarily of giant migrating contractions, in response to stretch in the stomach following ingestion and byproducts of digestion entering the small intestine.

Roemheld syndrome is characterized strictly by abdominal maladies triggering reflexes in the heart. There are a number of pathways through which cardiac reflexes can occur: hormones, mechanical, neurological and immunological. [citation needed]
