Which of the following does not correctly describe basic regulation of digestive activity?

a. Digestive effectors are smooth muscle and glands.

b. conscious neural control

c. pH, stretch, and osmolarity are some of the inputs that can initiate digestive responses.

d. Short reflexes act locally in the GI tract.

The correct answer is: b. conscious neural control

Neural control of digestive tract is unconscious achieved via the autonomic nervous system.

Local nervous system of the digestive system is called the enteric or intrinsic nervous system. The major components of this nervous system are two networks or plexuses of neurons:

• The myenteric plexus - controls digestive tract motility

• The submucous plexus - regulates gastrointestinal blood flow and controls epithelial cell function.
