The Aging Muscle, Skeletal, and Integumentary Systems

Watch video lessons and learn how and why our skin, muscles and skeletal systems change as we age. These lessons are just a portion of Education Portal's online psychology courses. 

About this chapter

The Aging Muscle, Skeletal and Integumentary Systems - Chapter Summary and Learning Objectives

If you've ever wondered why people develop gray hair and wrinkles when they get older, this chapter can help you understand the anatomical changes that occur during the aging process. You'll discover how the soft tissues, known as muscles, deteriorate and weaken every year, which can lead to flabbiness and sagginess. The incredible shrinking skeleton will be covered, including why we start to look smaller in late adulthood. You'll also learn how cellular and glandular activities in the skin, the largest organ in our bodies, decrease with age and lead to dryness, thinness and a greater susceptibility to injury.

Additional topics include how these changes affect our ability to move around and how we feel about ourselves. When you've completed this lesson, you should be able to define and discuss the following:

  • The parts of the integumentary system and their functions, including skin, hair and nails
  • Muscle tissue types and functions, including those associated with the cardiac and skeletal systems
  • Bone cells, including osteoblasts and osteoclasts
  • Long bone parts, such as diaphysis, epiphysis and metaphysis
  • Age-related diseases of the bones and joints
  • The sleep patterns of the elderly

VideoObjectives
Integumentary System Describe the function of the integumentary system, including skin and hair.
How Hair, Skin and Voice Change with Age Discuss how our hair, skin and voices change with age.
Types of Muscle Tissue: Skeletal Cardiac and Smooth Compare and contrast skeletal, cardiac and smooth muscle.
Major Skeletal Muscle Functions Explain the major functions served by skeletal muscle.
The Skeletal System: Function and Terms Define the purpose and structures of the axial and appendicular skeletal systems. Identify the following cells and structures: osteoblasts, osteoclasts, diaphysis, epiphysis and metaphysis.
How Body Build Changes with Age Describe what happens to our body build with age.
How Age Affects Mobility Discuss the age-related changes that affect our ability to move around, including balance- and muscle-related effects. Identify and explain bone- and joint-related diseases, such as osteoporosis, osteoarthritis and rheumatoid arthritis.
How Self-Concept is Affected by the Physical Changes of Aging Explain how the appearance of gray hair, fat, wrinkles and other signs of aging can affect self-image.
Physical Appearance and Sleep Patterns in Late Adulthood Understand the changes in appearance and sleep patterns that occur during late adulthood.

This lesson will cover the three main layers of your skin, which includes the epidermis, dermis, and subcutis. In addition, we'll learn about other skin cells and tissue, such as adipose tissue, keratinocytes, melanocytes, and Merkel's cells.

In this lesson, we will explore the obvious changes to our body as we age: hair, skin and voice. We will examine common causes as well as what to expect around certain ages.

Have you ever wondered why muscle has different names such as striated, smooth, voluntary, or involuntary? This lesson describes the different types of muscle tissue based on their histology, mechanism of contraction, and regulation.

Did you know that skeletal muscle does more than just move our body parts? This lesson describes how skeletal muscles are used for movement, posture, swallowing, defecation, urination and homeostasis.

You'll learn about the two major divisions of our skeleton, the axial and appendicular skeleton, in this video lesson. In addition, you will find out how bone is formed, thanks to tiny little cells called osteoblasts and osteoclasts, and what the major parts of a long bone are.

Watch this lesson for a brief discussion of the physical and mechanical changes that occur to the human body and its systems as we age. Some of the body systems covered include skeletal, muscular, organ, and nervous systems.

This lesson examines the physical changes that occur to the mechanical body as we age. Specific regards are given to what decreases mobility, and why.

Here we will explore the how the changes that occur with older age, including skin, muscle and neurological, will change the self-concept and locus of control for individuals.

As people age, they experience many changes in their bodies. In this lesson, we'll examine some of the changes in physical appearance that happen in older adulthood, as well as how people's sleeping habits change in late life.
