A Stimulus is a feature of the environment that your body can detect
Metaplasia (refferig to a cell)
The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.
exagerrates the stimulus
The answer to this would mose probabaly be a stimulus. Because there are 2 types of stimuli Internal Stimulus and External Stimulus and so it has to be either one of these but the answer is stimulus.
The sudden drop in air temperature is a stimulus.
claustrophobia

no because it doesnt want to
Effectors
Temperature - Skin Receptors.
positive chemotaxis
refactory period
A response is always triggered by a stimulus. One example is in a neuron (nerve cell). Once a sensory stimulus is witnessed (a stimulus from one of the 5 senses), the cell hits an action potential, and the response is carried out. Simply put: A human eye is closed. Once the eye opens thousands of sensors in the eye pick up the photons bouncing off all objects (stimulus), and the human is able to see (response).
A stimulus A stimulus is a change that starts an electrochemical charge, an impulse, moving along a nerve cell.
Sodium ions enter the cell
it would be the strenght of the stimulus
The activation of a second messenger inside the receiving cell, the triggering of enzyme activity in the cell, and the change of permeability of the cell.
