Outline and evaluate the role of neural mechanisms in eating behaviour AO1: One way in which eating behaviour is controlled is by a process called homeostasis. This involves mechanisms which both detect the state of the internal environment and also correct the situation to restore that environment to its optimal state. The body has evolved two separate systems‚ one for turning eating on and another for turning it off. Glucose levels play an important role in producing feelings of hunger. When

GENERIC NAME:LABETALOL - ORAL (luh-BET-uh-lol) BRAND NAMES: Normodyne‚ Trandate DRUG CLASS AND MECHANISM: Labetalol is a drug that is used for treating high blood pressure. Nerves from the adrenergic nervous system travel from the spinal cord to arteries where they release norepinephrine. Norepinephrine attaches to adrenergic receptors on arteries and causes the arteries to contract‚ narrowing the arteries‚ and increasing blood pressure. Labetalol blocks receptors of the adrenergic nervous system

It is also involved in several other functions of the body including homeostasis‚ motor function control‚ food and water intake regulation‚ and sleep-wake cycle regulation. The hypothalamus’ primary function is homeostasis‚ which is to maintain the body’s status quo throughout every body system. The hypothalamus secretes two hormones‚ ADH and oxytoxin‚ which are stored in the posterior pituitary gland. It maintains homeostasis by controlling the secretion of hormones in the pituitary gland. In

reduced function or even die. Homoeostasis is the adapted ability of an organism to regulate its internal environment to deal with changes in the external environment. (Raven 1999) Animals are grouped into two separate categories in respect to homeostasis: conformers and regulators. Conformers‚ or ectotherms‚ are not capable of maintaining their internal environment when faced with unfavorable external conditions. Therefore‚ they are forced to constantly seek out favorable environments and exert
