Answer: The boys nervous system played a role by stimulating mechanism for regulation of food intake.
Explanation:
The nervous system is the system that detects and responds to changes both inside and outside the body. This system consists of the following parts:
--> The Central Nervous System: This is composed of the BRAIN and the SPINAL CORD.
--> The Peripheral Nervous System: This is the rest of the nervous tissues that is found through the body that is outside the brain and the spinal cord. It consists of the SENSORY SYSTEM and the MOTOR SYSTEMS.
The centers that regulate food intake is the hypothalamus which is located immediately above the pituitary gland of the human brain. The sensation of hunger is associated with a craving for food, rhythmical contraction of the stomach and restlessness which cause the person to search for food. This is because the lateral nuclei of the hypothalamus which serves as the feeding center has been stimulated.
After the boy has eaten a piece of burger, the ventromedial nuclei of the hypothalamus receives neural signals from the gastrointestinal tract that provides sensory information about stomach filling and chemical signals from nutrients in the blood that signify satiety (fullness).
