About This Chapter
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
|The Sensory System||Provide an overview of the sensory system.|
|Introduction to Sensation and Perception||Identify the means and mechanisms by which humans respond to external stimuli.|
|How Age Effects Our Senses||Discuss the age-related changes that affect the senses, including those associated with balance, hearing, smell, taste and vision. Include how somesthesia, or bodily sensations, are affected.|
|Sensory and Motor Changes in Late Adulthood||Understand the physical changes that occur during late adulthood, including sensory and motor changes, changes in reaction time, organ reserve and physiological reactions.|
1. The Sensory System: Definition, Parts & Functions
This lesson will examine how the sensory systems are integrated and how they function as a whole. Instead of telling you ears hear and eyes see, we will examine how these systems are actually very similar in terms of reception, signals, and translations.
2. Intro to Sensation and Perception
What is the difference between sensation and perception, and how do they work? You'll get to see how the mind handles and differentiates between multiple sensations in this introduction.
3. How Age Affects Our Senses
This lesson is a broad summary of the changes that occur to your senses as you age. We examine the five classic senses, as well as the more obscure, such as balance and the varying types of skin sensations.
4. Sensory and Motor Changes in Late Adulthood
As people age, their senses change and dull. But why does this happen? In this lesson, we'll examine the changes in the brain and nervous system that cause a decline in sensory perception in later life.
