A
chemoreceptors, mechanoreceptors, photoreceptors, thermoreceptors, nocireceptors
2
Q
what is a chemoreceptor
A
a detector that detects chemical stimulis
3
Q
what is a mechanoreceptor
A
a detector that detects physical stimulus
4

A
a detector that detects light
5
Q
what does a thermoreceptor detect
A
changes in tempreature
6
Q
what does a nocireceptor detect
A
intense chemical physical or thermal stimulation
7
Q
where does exteroceptor receive signals from
A
external sources
8
Q
where does interoceptors receive signals from
A
internal environments
9
Q
what do interoceptors do
A
maintain internal environment within narrow limits, allow maximum cellular efficiency
