I know when talking about reflexes, what a reflex arc is...but what exactly is the feedback loop?

Is this correct: feedback loop - resists lengthening of muscle.

also what is efferent control and the role of the brain, spinal cord in reflexes?

Reactions in the body are usually controlled by factors which in turn are controlled by products of tht particular reaction.

For eg: LH stimulates the follicles to release estrogen and too much of estrogen then inhibhits LH at one point. Thats called a feedback loop
