A network of neurons within the gut wall that controls digestive functions.

Waves of muscle contractions that move food along the digestive tract.

Nerve cells that release chemicals to stimulate a response.

Nerve cells that release chemicals to inhibit a response.

A neurotransmitter that stimulates muscle contractions and increases secretions in the gut.

A neurotransmitter that inhibits muscle contractions and reduces gut activity.

The part of the nervous system that controls involuntary functions like digestion.

The branch of the autonomic nervous system that 'rest and digest'.

The branch of the autonomic nervous system that prepares the body for 'fight or flight'.

The ability of the enteric nervous system to function independently of the central nervous system.

One of the two major plexuses within the enteric nervous system, located between the longitudinal and circular muscle layers of the GIT, primarily involved in regulating muscle movements.

The other major plexus within the enteric nervous system, located between the circular muscle layer and the muscularis mucosae, primarily involved in regulating secretions, absorption, and local blood flow.

The ability of the myenteric plexus to increase the strength and frequency of muscle contractions within the GIT.

The myenteric plexus can increase the speed at which food and waste move through the digestive tract.

The myenteric plexus can increase the overall tone or tightness within the GIT muscles.

The submucosal plexus is responsible for regulating the production and release of digestive juices by the glands within the gastrointestinal tract.

The submucosal plexus controls how nutrients and water are absorbed from the gut into the bloodstream.

The ability of the submucosal plexus to regulate the contraction of smooth muscle within the mucosal layer, which helps to create folds that increase the surface area for absorption.

The collection of nerve fibers and ganglia within the enteric nervous system, playing a vital role in regulating gastrointestinal functions.

The muscle contractions that move food through the digestive tract. They work independently of the nervous system.

Processes that involve the release of fluids and enzymes in the digestive system. They happen without the nervous system's direct control.

The sequence of events that occur when food is detected in the mouth, leading to digestive responses.

The largest salivary gland, located near the ear.

The salivary gland found below the jaw, on either side.

The salivary gland located beneath the tongue.

The enzyme that breaks down starch into sugar.

The enzyme that breaks down fats, activated in the stomach.

The watery part of saliva, with enzymes and ions, produced by salivary glands.

The thicker part of saliva, containing mucus, produced by salivary glands.
