Ch 44: Holt McDougal Modern Biology Chapter 45: Skeletal, Muscular, and Integumentary Systems

About This Chapter

The Skeletal, Muscular, and Integumentary Systems chapter of this Holt McDougal Modern Biology textbook companion course helps students learn the essential modern biology lessons of the skeletal, muscular, and integumentary systems. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Skeletal, Muscular, and Integumentary Systems textbook chapter.

How it works:

  • Identify the lessons in the Holt McDougal Modern Biology Skeletal, Muscular, and Integumentary Systems chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the skeletal, muscular, and integumentary system topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Tissues and epithelium of multicellular organisms
  • Organ systems
  • Functions of the skeletal system
  • Anatomy and types of bones
  • Structure and functions of joints
  • Three types of muscle tissue
  • Role of sliding filaments and the sarcomere in muscular contraction
  • Types and functions of skeletal muscle fibers
  • Dermal and epidermal layers
  • Hair and nail structures
  • Glands of the integumentary system

Multicellular Organisms, Tissues and Epithelium

1. Multicellular Organisms, Tissues and Epithelium

In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.

What Is an Organ System? - Definition & Pictures

2. What Is an Organ System? - Definition & Pictures

In this lesson, you will learn what an organ system is, and you will review each organ system in the human body. This will aid in your study of human anatomy and physiology. At the end of the lesson, a quiz will test your knowledge.

The Skeletal System: Function and Terms

3. The Skeletal System: Function and Terms

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.

Anatomy of a Bone: Parts, Marrow & Types

4. Anatomy of a Bone: Parts, Marrow & Types

In this lesson, you'll learn how to classify bones by their shape. Additionally, you'll discover the structural makeup of bone and the different bone markings.

Joints: Structure and Functions

5. Joints: Structure and Functions

Find out what part of your body is affected when you tear your meniscus, how synovial fluid is made, what the synovial membrane helps to comprise, what a joint is, and why a joint capsule is important.

Types of Muscle Tissue: Skeletal, Cardiac & Smooth

6. Types of Muscle Tissue: Skeletal, Cardiac & Smooth

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.

The Sarcomere and Sliding Filaments in Muscular Contraction: Definition and Structures

7. The Sarcomere and Sliding Filaments in Muscular Contraction: Definition and Structures

Did you know that a sarcomere is the fundamental functional unit of striated muscle? This lesson describes the thick and thin filaments of a sarcomere and how they interact with each other to cause sarcomere shortening and muscular contraction.

Skeletal Muscle Fibers: Types and Functions

8. Skeletal Muscle Fibers: Types and Functions

Did you know most human muscles contain a mixture of fast, slow and intermediate fibers? This lesson describes the structure and function of the three muscle fiber types found in humans.

The Integumentary System: The Epidermal Layer

9. The Integumentary System: The Epidermal Layer

Do you know what the largest organ in your body is? How about the layers of your skin? Or where skin cancer comes from? Learn the answers to these questions and more in this lesson on the integumentary system.

The Integumentary System: The Dermal Layer

10. The Integumentary System: The Dermal Layer

Did you know that some people don't feel pain? Or that some always feel as if their skin is on fire? Learn about the causes of these diseases and the anatomy of the skin they affect in this lesson- the dermal layer of the skin.

The Integumentary System Accessory Structures: Hair

11. The Integumentary System Accessory Structures: Hair

Your skin does more than just cover your body; it has a number of structures like hair and sweat glands. Learn more about the hair that protects your body in this lesson.

The Integumentary System Accessory Structures: Nails

12. The Integumentary System Accessory Structures: Nails

Did you know that your skin, hair, and nails are all made out of the same protein? Learn more about the structure and function of your nails in this lesson.

The Integumentary System Accessory Structures: Glands

13. The Integumentary System Accessory Structures: Glands

Ever wonder how pimples appear? Is it simply a blocked pore or maybe a hair follicle? Is bacteria involved? Learn about the glands that cause acne and the glands that help you cool off in this lesson on sebaceous and sweat glands of the integumentary system.
