1
a region of the brain called the hypothalamus, signals an effector (e.g. muscles or an organ ) to respond to the stimuli
2
characterized by their ability to either increase or decrease a stimulus, inhibiting the ability of the stimulus to continue as it did prior to sensing of the receptor
3
is a process in which the end products of an action cause more of that action to occur in a feedback loop
4
is the ability to maintain a relatively stable internal state that persists despite changes in the world outside
5
the body site where a response is generated, which counters the initial stimulus and thus attempts to maintain homeostasis
6
a response within a system (molecule, cell, organism, or population) that influences the continued activity or productivity of that system. In essence, it is the control of a biological reaction by the end products of that reaction
7
a change in the environment, such as an irritant, loss of blood, or presence of a foreign chemical
8
the site within the body that detects or receives the stimulus , senses the change from normal, and sends signals to the control center
9
a reaction to something, in this case, the reaction to a stimulus
10
are chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions
