**Core Concept**
Intestinal motility refers to the rhythmic contraction and relaxation of intestinal smooth muscle, which helps propel food through the gastrointestinal (GI) tract. This process is crucial for the proper digestion and absorption of nutrients. Intestinal motility is regulated by a complex interplay of hormonal, neural, and myogenic mechanisms.

**Why the Correct Answer is Right**
The correct answer will be a statement that accurately describes a characteristic of intestinal motility. For example, the migrating motor complex (MMC) is a pattern of electrical activity that helps maintain the integrity of the GI tract during periods of fasting. The MMC consists of three phases, including a fasting activity phase that helps clear the stomach and small intestine of residual food particles.

**Why Each Wrong Option is Incorrect**
* **Option A:** This statement might describe a characteristic of intestinal motility, but it is not an exception to the true statement about intestinal motility.
* **Option B:** This statement is incorrect because intestinal motility is indeed influenced by the enteric nervous system (ENS), which is often referred to as the "little brain" of the GI tract.
* **Option C:** This statement is incorrect because the GI tract does exhibit periods of increased motility, such as during the digestive phase after eating.
* **Option D:** This statement is incorrect because the intestinal motility pattern is altered in conditions such as gastroparesis, which is characterized by delayed gastric emptying.

**Clinical Pearl / High-Yield Fact**
The intestinal motility pattern can be influenced by various factors, including hormones (e.g., gastrin, secretin), neural inputs (e.g., vagus nerve stimulation), and myogenic factors (e.g., muscle contraction). Understanding the complex interplay of these factors is essential for diagnosing and managing disorders of intestinal motility.

**Correct Answer:** D.
