Copyright © 2009 Pearson Education, Inc., publishing as Pearson Benjamin Cummings Classification of Bones Bones are classified by Shape Internal tissue organization Bone markings (surface features; marks)
Copyright © 2009 Pearson Education, Inc., publishing as Pearson Benjamin Cummings Classification of Bones Bone Shapes Long bones Are long and thin Are found in arms, legs, hands, feet, fingers, and toes Flat bones Are thin with parallel surfaces Are found in the skull, sternum, ribs, and scapulae Sutural bones Are small, irregular bones Are found between the flat bones of the skull
Copyright © 2009 Pearson Education, Inc., publishing as Pearson Benjamin Cummings Classification of Bones Bone Shapes Irregular bones Have complex shapes Examples: spinal vertebrae, pelvic bones Short bones Are small and thick Examples: ankle and wrist bones Sesamoid bones Are small and flat Develop inside tendons near joints of knees, hands, and feet
Copyright © 2009 Pearson Education, Inc., publishing as Pearson Benjamin Cummings Classification of Bones Structure of a Long Bone Diaphysis The shaft A heavy wall of compact bone, or dense bone A central space called medullary (marrow) cavity Epiphysis Wide part at each end Articulation with other bones Mostly spongy (cancellous) bone Covered with compact bone (cortex) Metaphysis Where diaphysis and epiphysis meet
Copyright © 2009 Pearson Education, Inc., publishing as Pearson Benjamin Cummings Classification of Bones Structure of a Flat Bone The parietal bone of the skull Resembles a sandwich of spongy bone Between two layers of compact bone Within the cranium, the layer of spongy bone between the compact bone is called the diploë
Copyright © 2009 Pearson Education, Inc., publishing as Pearson Benjamin Cummings Compact and Spongy Bone The Structure of Compact Bone Dense Rigid Harder than spongy bone Little space
Copyright © 2009 Pearson Education, Inc., publishing as Pearson Benjamin Cummings Compact and Spongy Bone The Structure of Spongy Bone The matrix forms an open network The space filled with red bone marrow: Which has blood vessels Forms red blood cells And supplies nutrients to osteocytes Yellow marrow In some bones, spongy bone holds yellow bone marrow Is yellow because it stores fat

The Skeletal System Supports the body Protects soft organs Allows movement due to attached skeletal muscles Stores minerals and fats Blood cell formation.

Chapter 5 – The Skeletal System Support the body Protect soft organs Allow movement due to attached skeletal muscles Store minerals and fats Blood cell.
Chapter 10: Movement and Forces 10.1 The skeletal system provides movement and protection 10.2 The muscular system makes movement possible 10.3 Muscles.
Lesson 1 How is it possible for you to perform motions such as stretching and rolling your shoulders? The interaction of bones and muscles allows you.

Bones and Skeletal Tissues Structure and Function of Cartilage and Bone.
Describe the structure and function of the skeletal system Describe the different classifications of joints Identify the location of the major muscles.
