Physiology wk1 Flashcards
what is translational research
bench to beside application of research findings
what is applied research
studies designed to solve practical problems
what is basic research
systematic study of fundamental topics in biology
what is homeostasis
maintenance of internal environment regardless of external change
what is steady state
when the physiological variable isn’t at normal levels but is also unchanging (mean arterial blood pressure)
what are the intracellular control systems
Protein breakdown/synthesis
Energy production
Maintenance of stored nutrient
what is included in the organ systems
The pulmonary and circulatory system
Replenishment of O2 and removal of CO2
whats the process to return a stimuli to normal levels
Stimuli -> picked up by sensor -> message to control centre -> activates effectors -> negative feedback returned to normal
what is negative feedback
when stimuli are returned to normal level
what is positive feedback
when the stimuli is furthered to carry on and increase
what is cell adaption
change in structure and function of a cell/organ system which results in approved ability to maintain homeostasis
acclimation
adaption to environmental stresses resulting in improved function of existing homeostatic system
what is Hormesis
when a low to moderate dose of stress is inflicted onto someone resulting in a beneficial adaptive response on organs and cells
what is cell signaling
the process of communication between cells using chemical messengers (CM)
what type of cell signaling is intacrine
CM inside cell triggers response
