In the reflex arc what is the function of the afferent fiber ?
1.to carry signal from the integration center out to the effector, so the effector can respond appropriately
2. to carry the signal from the receptor to the integration center for processing
3. it detects change
4. none of the above

Afferent nerve fibers carry signals from the somatic receptors to the posterior horn of the spinal cord or to the brainstem. So i beleive it is 4 but not too sure. Hope this helped a bit (:

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
