Receptors And Sense Organs Flashcards
What do sensory organs contain
Receptors
what are the 4 types of receptors
Chemoreceptors, thermoreceptors, mechanoreceptors, photoreceptors
What do chemoreceptors detect
Presence of chemicals
What do thermoreceptors detect
Change in temperatures
What do mechanoreceptors detect
Mechanical changes in the environment
What do photoreceptors detect
Light
What do receptors detect
Stimuli and change a a result of the stimuli
What are the 5 sense receptors
Auditory, somatosensory, olfactory, gustatory and visual

What are somatosensory sence receptors
The skin contains a variety of receptors which respond to temperature or pressure for exampl whiskers
Wha are olfactory ene receptors
Receptors in the nasal cavity responding to odour molecules in the air.
What are gustatory sense receptors
The tongue on many animals contai papillae which contai taste buds. These respond to food and drink to give different sensations of taste.
