negative feedback loops

negative feedback loops

reversal of stimulus

homeostasis control mechanism

stimulus → controlled condition → receptor → input → control center → output → effector → response → stimulus

what is a stimulus

anything that causes change or response in a cell or organism

what is controlled condition

a physiological parameter ,maintained in a narrow range

what is a receptor

a specialized nerve ending that detects and monitors controlled condition

what is input

communication, nerve ending between receptor and control center

what is control center

integrates incoming information, generates output

what is output

communication between control center and effectors involved

what is effector

tissue, organ or gland that generates a response

what is response

action of effector

what are hormones

control target organs far from their source, send signals to stop breaking ATP

controlled condition example

body temperature- have a range that is sill considered okay

receptor example

thermoreceptor

input example

nerve impulse. sometimes a hormone

control center example

hypothalamus

output example

nerve impulse, sometimes a hormone

effector example

sweat gland

response example

increased sweat production
