Document Summary
Output signal is also known as the afferent pathway as well as the motor pathway. The target cell will be able to move the hand away. Ultimate response at the end of the response loop. Three different types of reflex control pathways: negative feedback. Is taking something away eg. so when you touch something hot you remove your hand away from something hot: will always starts with a stimulus, go through all those processes, target and then a response. The ultimate response at the end will feedback on the stimulus and return back to the original state. Job of negative feedback control mechanisms is to keep things around the set point. Fig 1. 12 a: initial stimulus, response: in negative feedback decreases that initial stimulus (a) response counteracts the stimulus (b) shuts off response loop, stimulus (a) decreased from the initial stimulus, positive feedback. Fig 1. 13 the birth canal and the head will push on the cervix.
