» span 9 pts Question 3 There are three essential components of all homeostatic control mechanisms: control center, receptor, and effector. The I senses changes in the environment and responds by sending information (input) to the receptor along the pathway. The analyzes the input, determines the appropriate response, and activates the by sending information along the pathway. When the response causes the initial stimulus to decline, the homeostatic mechanism is referred to as a feedback mechanism. When the response enhances the initial stimulus, the mechanism is called a feedback mechanism. feedback mechanisms are much more common in the body. Question 4 5 pts List the levels of organization from atom to organisnm 1. Atom 2.Explanation / Answer
The answer is as follows :
1. Receptor
2. Controll center
3. Receptor Pathway /Affector pathway
4. Controll center
5. Effector
6. Effector Pathway
7. Negative
8. Positive
9. Negative
The explanation is:
Homeostatis reffers to the ability of the body to maintain internal optimum conditions or stability or equilibrium, during fluctuations in external or internal conditions due to any plausible reason.
The principle component involved are RECEPTORS (which recives the signal or stimulus), THE CONTROLL CENTER (which process the signal) and EFFECTORS (which enacts the countermeasure).
The negative feedback mechanism maintains homeostatis in body by responding to a change parameter in the opposite direction of the environmental change, While the posititivefeedback mechanism is the vice versa, i.e. the body maintains homeostatis in by responding to a change parameter in the same direction of the environmental change thus amplify the change and is a subpart of negative feedback.
In the body the negative feedback mechanism is more abundant.
