7 important questions on Tutorial title - Sensory (afferent) division - Sensory Receptors
Sensory receptors are structures that pick up changes in the internal and external environment (action called “sensation”). They function on 2 rules, what are these rules?
The stimulus must be applied within a receptive field
Changes in the internal or external environment (stimuli) activate sensory receptors and result in depolarizations that trigger impulses to the CNS. What is the 6 step procedure to that propagated impulse to the CNS?
How do the different types of receptors turn a very specific stimulus into a nerve response?, a process called transduction
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Once the impulse is propagated to the CNS what do the relevant areas in the brain do with this information?
Why are sensory receptors classified by stimulus type, by location in the body, and by structural complexity
Photoreceptors detect electromagnetic energy in the form of what?
Chemoreceptors detect chemicals in which 2 to areas? Give some examples
They detect chemicals in the body and the environment.They measure levels of oxygen, carbon dioxide, and pH in the blood.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
