is the simplest pathway with only a few neurons involved. 

~Structural and functional basis for reflexes 

~Begins with a receptor at the end of the sensory fiber 

*this fiber leads to the interneurons within CNS

•this is the reflex center or processing center 

*then communicate with motor neurons to effectors

~Reflex: automatice subconsioous responses to change (stuimuli) within or outside the body.

-help maintain homeostasis

-control involuntary process 

*heartrate, breathing rate, blood pressue, digestion

*swallowing, sneezing, coughing, vomiting

-When person unexpentedly touches a body part to something painful

- Activates skin receptors and send impulses to spinal cord

- Pass though interneuron to motor neuron

-Interneuron carries sensory information to brain

*Person becomes aware of experience and may feel pain

-Protective: Limits tissue damage
