VERSION 2025/2026.
Sensory Systems - ANS Provide Animals With All Of The Information They Have About Their
External And Internal Environments
-Sense Organs For A Category Of Stimulus And All Of Their Associated CNS Processing Systems
What Do Sensory Systems Rely On - ANS Sensory Receptor Cells
Sensory Receptor Cells - ANS Respond To Stimuli
-These Cells Can Vary In Sensitivity And Specificity
-A Cell That Is Specialized To Transform The Energy Of A Stimulus (Chemical, Electrical, Or
Electromagnetic) Into An Electrical Signal
-Commonly Clustered Together In Sense Organs
Sense Organs - ANS Anatomical Structures That Re Specialized For Reception Of Particular
Kinds Of Stimuli
Sensitivity Of Sensory Cells - ANS Ability To Distinguish Among Stimuli Of Different Intensities
Specificity Of Sensory Cells - ANS Ability To Distinguish Among Stimuli Of Different Types

, Classification Of Sensory Receptor Cells - ANS -Sensory Modality
-Form Of Stimulus Energy
-Mechanism Of Transduction
-Location Of Source Of Stimulus Relative To Animal Body
Sensory Modality - ANS Subjective Nature Of The Sensory Stimulus
-Aristotle Classified These As Vision, Hearing, Touch, Smell, And Taste
-However, We Know That Animals Also Respond To Balance, UV Radiation, Temp, Magnetism,
And Electric Fields
Form Of Stimulus Energy - ANS Different Forms Of Electromagnetic Energy And Mechanical
Energy Can Stimulate Different Sensory Receptor Cells
Mechanism Of Transduction - ANS Ionotropic Or Metabotropic
Ionotropic Transduction - ANS Sensory Stimuus Is Transduced Into An Electrical Signal
Directly Via Increased Membrane Permeability To Ions
Metabotropic Transduction - ANS Sensory Stimulus Is Transduced Into An Electrical Signal
Indirectly Via A Metabolic Cascade That Eventually Leads To Changes In Membrane
Permeability
Location Of Source Of Stimulus Relative To Animal Body - ANS Exteroceptors
Interoceptors
Exteroceptors - ANS Sensory Cells That Respond To Stimuli Outside The Body
Interoceptors - ANS Respond To Internal Stimuli
