General Characteristics of Sensory Function
Responds to stimuli when they are specific for then transducing it into a neural message that follows a path to the brain
Receptors, Sensation and Perception
There are sensory receptors that detect stimulation and perception which is the interpretation of sensory information
General Senses
may focus on the somatosensory system which includes touch, temperature, pain, and awareness of body position
Special Senses
Covers the sense of vision, hearing, taste, smell, and equilibrium processed via cranial nerves and differs from the general senses pathway
Life-Span Changes
How sensory function changes throughout the lifespan and declines because of age-related changes that affect their sensory abilities and sensory function
