CH.5 The Skeletal System Flashcards
Blood cell formation is called
Hematopoiesis
Yellow Marrow is a storage area for
Adipose tissue
List all examples of flat bones
Skull, ribs, sternum (breast bones)
List all examples of long bones
Humerus, all bones of the limbs
List all examples of short bones
Patella, Tallis, carpals(wrist), tarsals (ankle)
List all examples of irregular bones
Axial, vertebrae, tailbone ( )
What parts of the skeletal system make up the axial skeleton
Vertebra, sternum, ribs, skull, thoracic cage
What parts of the skeletal system make up the appendicular skeleton
Femur, scapula, radius, metatarsals, humerus, tibia, bones of the limbs
Two important minerals stored in the bones
Calcium and phosphorus
What is appositional growth
The process of bones increasing in diameter
What is the function of the articular cartilage and where is it found
It provides a smooth, slippery surface that decreases friction at joint surfaces// covers the proximal epiphyses
What type of tissue is found in the embryo and will turn into bone with time
Hyaline cartilage
List the four stages of healing of a bone fracture in order from beginning to end
Hematoma forms
Fibrocartilage callus forms
Bony callus forms
Bone remodeling occurs
When the bone is broken and exposed to the outside you have a ________________ Fracture
Open( compound )fracture
When the bone breaks cleanly but does not penetrate the skin you have a __________________ fracture
Closed (simple)
When the bone is broken into many fragments you may have a ______________ fracture
Comminuted
A fracture that is common in children is called a ____________
Green stick
A fracture that is common in osteoporotic bones is called a
Compression
Where is the squamous suture located
Between that partiel and temporal bones
What are the fontanels and their function
Fibrous connections between the bones of a fetal skull
What is the only bone of the body that does not directly articulate with any other bone
Hyoid bone
What are the functions of bones
Support, movement, protection, storage, and blood cell formation
What part of the bone causes the lengthwise growth of a long bone
Epiphyseal plate
