Key Points
- Glucostatic Theory:
- Proposes that the body's need to maintain homeostasis in blood glucose levels is a primary driver of hunger and eating behavior.
- According to this theory, low blood glucose levels trigger the sensation of hunger, prompting food intake to restore glucose levels.
- Cephalic Phase:
- Refers to the early phase of digestion, preparing the body for food intake through sensory inputs such as sight, smell, taste, and thought of food.
- This phase involves neural responses that stimulate digestive secretions and hormonal responses even before food is consumed.
- Absorptive Phase:
- Occurs when the body’s intake of food initiates metabolic processes to absorb and store nutrients from the digestive system.
- This phase involves the conversion of nutrients into energy and storage forms such as glycogen and fat.
- Leptin:
- A hormone produced by adipose (fat) tissue that regulates long-term energy balance and signals satiety to the brain.
- Leptin helps to prevent overeating by inhibiting hunger and promoting energy expenditure when fat stores are sufficient.
Additional Information
- Incorrect Options:
- Option 2: Incorrectly matches Glucostatic Theory with Cephalic Phase and vice versa, leading to confusion between blood glucose regulation and preparatory sensory inputs.
- Option 3: Incorrectly matches all pairs, confusing the fundamental phases and roles of glucose regulation, sensory inputs, metabolism, and hormonal signals.
- Option 4: Incorrectly matches Glucostatic Theory with Absorptive Phase and Leptin with Cephalic Phase, thus misinterpreting the roles of glucose homeostasis and sensory preparation.
