LO a) the roles of mammalian sensory receptors in converting different types of stimuli into nerve impulses

HideShow resource information
What do sensory receptors do? And what are they also known as?
Detect changes in our surroundings and they're also known as transducers
1 of 5
What do receptor cells do?
They respond to a variety of stimuli e.g. pressure, temperature, light and sound by initiating an action potential
2 of 5
Give an example of a receptor, sense and form of energy this is received in
Rode/cone cells - sight - light, Taste buds - taste - chemical E, Ruffini's endings - temperature - heat
3 of 5
What is the process of the pacinian corpuscle?
Pressure on the skin increases, rings of concentric connective tissue deform, connective tissue pushes against nerve endings, action potential is generated
4 of 5
Give an example of a stimulus energy and stimulus.
Photoreceptor- electromagnetic - light intensity, thermoreceptor - thermal - temperature change
