Examples of cephalization in the following topics:
-
- All three phases of digestive responses to food (the cephalic, gastric, and intestinal stages) are managed through enzymatic neural control.
- There are three overlapping phases of gastric control: the cephalic phase, the gastric phase, and the intestinal phase.
- The first phase of ingestion, called the cephalic phase, is controlled by the neural response to the stimulus provided by food.
- The gastric and salivary secretion in the cephalic phase can also take place at the thought of food.
- It builds on the stimulation provided during the cephalic phase.
-
- They also show the beginning of cephalization: the evolution of a concentration of nervous tissues and sensory organs in the head of the organism, which is where it first encounters its environment.
-
- The evolution of bilateral symmetry and, therefore, the formation of anterior and posterior (head and tail) ends promoted a phenomenon called cephalization, which refers to the collection of an organized nervous system at the animal's anterior end.
