About This Chapter
Skeletal System - Chapter Summary and Learning Objectives
Your skeletal system is an important part of your body. Without it, you would be in serious trouble. In this chapter, we will explore the skeletal system with a look at what it does. You'll also get to examine the two main sections of the skeletal system. Lessons will look at the skull, face, vertebral column, ribs, arms, hands, shoulders, legs, feet and pelvis. You will also watch lessons that cover joints, including their functions and overall characteristics. Some of the specific things that will be covered include:
- Locations of the bones in the skull
- The axial and appendicular skeletal systems
- The anatomy of the hand
- Functions of bones in the leg
- Common characteristics of the joints
- Types of joints
|The Skeletal System: Function and Terms||Examine why the skeletal system exists and its two main sections - axial and appendicular.|
|Major Bones of the Skull: Names and Location||Explore the major bones of the skull, including frontal, parietal, occipital, temporal, sphenoid and ethmoid.|
|Bones of the Face: Names, Function & Location||Study the bones of the face, such as the maxilla, mandible, zygomatic, lacrimal, nasal, vomer and palatine.|
|Bones of the Vertebral Column and Ribs: Definition and Function||Discover the vertebral column and ribs, including vertebrae, sternum, ribs, manubrium, xiphoid and costal cartilage.|
|Bones of the Arm and Hand: Anatomy and Functions||Take a look at the anatomy of the bones in the arm and hand, including humerus, radius, ulna, carpals, metacarpals and phalanges.|
|Bones of the Shoulder: Anatomy and Function||Analyze the bones of the shoulder, such as the clavicle, scapula, glenoid cavity and acromion.|
|Bones of the Leg and Foot: Names, Anatomy & Functions||Examine the leg and foot, specifically bones like the femur, patella, fibula, tarsals, metatarsals and trochanter.|
|Bones of the Pelvis: Definition and Function||Explore the bones in the pelvis, such as the ilium, ischium, pubis, acetabulum, pelvic, cavity and sacrum.|
|Joints: Structure and Functions||Analyze the joints and related terms, such as bursa, joint capsule, synovial membrane and meniscus.|
|Types of Joint Movement & Tissue Structure and Function||Study the types of joint movements, classified by tissue type and by the amount of permissible movement of the joint.|
1. 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.
2. 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.
3. Bone Growth & Development Factors: Endochondral Ossification
In this lesson, you will learn about the two ways we form bones: intramembranous ossification and endochondral ossification. You'll also discover how our bones grow after we're born.
4. Major Bones of the Skull: Names and Location
Your eyeballs, ear and brain all depend on skull bones to give them a place to live. These bones include the frontal, parietal, occipital, temporal, sphenoid and ethmoid bone. Review these bones and their purposes in this lesson.
5. Bones of the Face: Names, Function & Location
In this lesson, learn which bones help you cry, breathe, eat and see as we review the maxilla, mandible, zygomatic, lacrimal, nasal, vomer and palatine bones of the face. Then, learn which bones are paired.
6. Bones of the Vertebral Column and Ribs: Definition and Function
Learn about the importance of your ribs, vertebrae, and sternum. If it wasn't for them, you wouldn't be alive. You'll also find out what strange sounding words like manubrium and xyphoid mean.
7. Bones of the Arm and Hand: Anatomy and Functions
The humerus isn't all that funny; it plays an important role in your body. Likewise, the radius, ulna, carpals, metacarpals and phalanges are all important components of your arm, wrist and fingers.
8. Bones of the Shoulder: Anatomy and Functions
Did you know that your shoulder joint is made up of many different parts? In this lesson, you'll learn about the clavicle, scapula, glenoid cavity, and acromion, as well as some of their more common names.
9. Bones of the Leg and Foot: Names, Anatomy & Functions
Find out about the major bones which help you walk. We'll go over the femur, patella, fibula, tibia, tarsals, metatarsals, and something called the trochanter.
10. Bones of the Pelvis: Definition and Function
In this lesson, you will learn about your hips and the important structures involved in their formation. The ilium, ischium, pubis, acetabulum, pelvic cavity, and sacrum will all be covered.
11. 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.
12. Types of Joint Movement & Tissue Structure and Function
Find out how your joints are categorized. You'll learn about the synovial, cartilaginous, and fibrous joints as well as diarthrosis, synarthrosis, and amphiarthrosis.
