#physiology definition

• Appetite — A strong inclination, intense desire, native attraction, or appetite for something (e.g., appetite for culture, appetite for risk). In physiology, it represents the organic drive or desire to satisfy a biological need, particularly appetite for food or reproductive urges.
• Appetitive — Stimulating, increasing, or relating to the appetite or to the tendencies to satisfy an organic drive; eupeptic. In classical psychology and scholastic philosophy, the term describes a faculty of the soul or a behavior oriented toward seeking and acquiring a desired object or fulfilling a biological need.
• Self-perception — A mental, cognitive, or sensory process through which an individual consciously perceives, decodes, and integrates their own internal states, emotions, impulses, or physiological signals; a structural reflexive act of becoming aware of the somatic and psychic self. In neurophysiology, it describes the nervous system's capacity to process native interoceptive and proprioceptive stimuli, forming the baseline for bodily identity and the mental representation of one's own ego.
• Auxotonic — Relating to or characterized by a muscular contraction in which the tension within the fibers progressively increases as the muscle shortens (elongates); specific to movements executed against a variable elastic resistance (such as stretching a spring or the ejection phases of the heart).
• Auxotonie — A physiological phenomenon or process consisting of a muscular contraction during which the internal tension of the fibers progressively increases concurrently with the shortening of their length; a mechanical activity regimen characteristic of the myocardium during the blood ejection phase or skeletal muscles overcoming a variable elastic resistance.
