Chapter 13: Peripheral Nervous System and Reflexes
... A reflex is a rapid, predictable motor response to a stimulus. Can be either inborn (involuntary and intrinsic) or learned (still involuntary, though). Many spinal reflexes occur without the involvement of higher brain centers. Muscle spindles: receptors in skeletal muscle that are sensitive to stre ...
