What is a digestive reflex when thinking about long and short digestive reflexes? Why are they important for efficent digestive nutrients and give examples of how they respond to stimuli?

Expert Solution

The digestive system has a complex system of motility and secretion regulation which is vital for proper function. It is accomplished via - Long reflex, Short reflex and reflex from GI peptides working in harmony.

Long reflexes to the digestive system involve a sensory neuron sending external or internal digestive information to the brain. This type of reflex includes reactions to food, emotion, or danger.

IMPORTANCE:

These include that control much GI secretion, peristalsis, mixing contractions, local inhibitory effects.

It includes:

• Vagovagal reflex

• Pain reflex

• Defecation reflex

• Vomiting reflex

How they act?

Short reflexes to the digestive system provide shortcuts for the enteric nervous system (ENS) to act quickly and effectively, and form a sort of "digestive brain". It reacts to digestive movement and chemical changes.

These reflexes transmit signals to other areas of GI tract. It includes:

• Gastrocolic reflex

• Enterogastric reflex

• Colonoileal reflex

• Ileogastric reflex

IMPORTANCE: In general, They control the motility, or peristalsis, of the gastrointestinal tract following a meal. They also regulate the secretion of GI juices.
