Introduction Part 4 Flashcards
What is a local homeostatic response?
It is the result of a sequence of events proceeding from a stimulus.
Where does a local homeostatic response occur?
It occurs only in the area of the stimulus
What does a local homeostatic response provide?
Individual areas with mechanisms for local self-regulation.
How is intercellular communication performed?
Performed by chemical messengers
What are some examples of chemical messengers?
Hormones
Neurotransmitters
Paracrine agents
What do chemical messengers participate in?
Reflexes and local responses
What can a particular messenger function as?
A Neurotransmitter
A Hormone
A Paracrine/Autocrine agent
How is intercellular communication achieved?
By Neurotransmitters, hormones and paracrine agents
What are the less common forms of intercellular communication?
Intercellular communication through either gap junctions or cell bound messengers
What is autoregulation?
An Adaptive reaction that is independent of nerve or hormonal factors •
Characteristics of Neural regulation
Rapid
Accurate
Short
Characteristics of humoral regulation
Slow
Lasting
Dispersed
Characteristics of autoregulation
Maintain within a narrow range
What do homeostatic control systems do in relation to each other?
Cooperate and Compensate
