Directional stimuli are environmental stimuli, particularly light and sound, that the direction of which it comes and the direction of the response to the stimulus are of upmost importance. Non-directional stimuli are those where receptors do not detect the direction from which they come. Chemical stimuli are usually not directional.
Eyes and ears, because the other three senses are not possible to detect a distance object.
Touch - Mechanical receptors Light- Photo receptors Heat- Thermo receptors
Its called a nerve net, like a nervous system but not as good.
The presence/concentration of chemical compounds (in air and food/water, respectively).
Chemoreceptores can detect chemical stimuli.
sensory cells
The epidermis.
Chemoreceptores can detect chemical stimuli.
sensory
ability to detect how much stimuli is applied to the body
sensory neurons
This ability is known as Weber's Law, which states that the smallest change in a stimulus that can be detected is proportional to the magnitude of the original stimulus. The law suggests that the ability to detect changes in stimuli depends on the intensity or strength of the original stimulus.
