Motility and secretion in the stomach is generated by the reflex initiated by thought, smell, sight, or taste of food.

Explanation:

The cephalic phase reflex of gastric secretion, which is relatively brief, takes place before food enters the stomach

The smell, taste, sight, or thought of food triggers this type of reflex

For example, when we bring a piece of food item to our lips, impulses from receptors in our taste buds or the nose are relayed to our brain, which returns signals that increase gastric secretion to prepare our stomach for digestion

This enhanced secretion is a conditioned reflex, which means it occurs only if we like or want a particular food

Depression and loss of appetite are two factors which can suppress the cephalic reflex

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
