The Aging Sensory System - Chapter Summary and Learning Objectives

In this chapter, you'll learn how the aging process affects the sensory system, the part of our nervous system that processes our voluntary and involuntary responses to stimuli. You'll begin with an introduction to the various systems that enable us to hear, see, smell, taste and touch, as well as those that dictate our sense of balance and movement. The instructor will also discuss how we respond to external stimuli, such as heat, light or sound, and then process those responses through our nervous systems.

The age-related effects on our five senses will also be covered, including how aware we are of our bodies in relation to their physical surroundings. Additional topics include how our sensory responses slow with age and the relationship between motor changes and physiological reactions, such as those associated with muscles and organs. After you complete this chapter, you should be able to identify and discuss:

  • The subsystems that make up the human sensory system, including the auditory, olfactory and visual systems
  • Sensation and perception, including how we organize and interpret sensory information
  • Somesthesia or how we experience our bodies, pain and touch
  • Organ reserve and the ability of our bodies to support life
