Document Summary
Voluntary movements are incited to occur (motivate) in order to satisfy a need. Motivation can be very abstract (e. g. the need to go sailing on a warm and breezy summer) or very concrete (e. g. Motivation can be very abstract (e. g. the need to go sailing on a warm and breezy summer) or very concrete (e. g. going to the bathroom because your bladder is full) Motivation can be thought of as a driving force on behaviour. The hypothalamus plays a key role in the regulation of body temperature, fluid balance, and energy balance. Homeostasis is the processes that maintain the internal environment of the body within a narrow physiological range. Hypothalamic regulation of homeostasis starts with sensory transduction. A regulated parameter is measured by specialized sensory neurons and deviations from the optimal range are detected by neurons in the periventricular zone of the hypothalamus. Example: you are cold, dehydrate, and depleted of energy.
