Multiple Choice

Which of these statements about reflexes in the gastrointestinal (GI) tract is false?

All reflexes in the GI tract require input from the brain.

GI reflexes can regulate the secretion of digestive enzymes.

The enteric nervous system can function independently of the central nervous system.

Reflexes in the GI tract can be initiated by the presence of food.

Verified step by step guidance

Understand the role of the enteric nervous system (ENS) in the gastrointestinal (GI) tract. The ENS is a network of neurons that can operate independently of the central nervous system (CNS) to regulate digestive processes.

Recognize that GI reflexes can be initiated by various stimuli, including the presence of food in the digestive tract. These reflexes help coordinate activities such as peristalsis and enzyme secretion.

Identify that the statement 'All reflexes in the GI tract require input from the brain' is false. Many reflexes are mediated by the ENS without direct involvement from the brain.

Consider the role of GI reflexes in regulating the secretion of digestive enzymes. These reflexes are crucial for adapting enzyme release based on the contents of the GI tract.

Conclude that the false statement is the one suggesting that all GI reflexes require brain input, as the ENS can independently manage many reflexive actions within the GI tract.
